Process value alarm Process value 4-point alarm (LL, L, H, HH), alarm hysteresis, and ON-delay timer (0 to 60 s) are available. Rate-of-change calculation Calculates the amount of change per comparison time interval (1 to 16 s).

Adjustment period control When zero/span adjustment is executed, the date is internally recorded at the Unit. When the preset zero/ span adjustment period and number of days notice have elapsed (allocated in Expansion Setting Area), this function turns ON a warning flag to give notice that it is time for readjustment. Peak and bottom detection This function detects the maximum (peak) and minimum (bottom) analog input values, from when the Hold Start Bit (output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF, and stores them in the Expansion Control/Monitor Area. Top and valley detection This function detects the top and valley values for analog inputs, from when the Hold Start Bit (output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF, and stores them in the Expansion Control/Monitor Area.

The input range can be set anywhere within the measurable input ranges shown in the following table. Accuracy and resolution, however, are not determined from the set input range, but rather from the measurable input range shown in the following table. Therefore, accuracy and resolution do not change even when a narrow input range is set.

For example, short terminals A4 and B5 for No. 2 thermocouple input. • Cold junction sensors are mounted between A1 and A2, and A6 and A7 before shipment. If one of the cold junction sensors is disconnected, cold junction compensation will stop and correct measurement of temperatures cannot be made. Always make sure the cold junction sensors are connected when using the Units. • Cold junction sensors are calibrated separately for each Unit and connected circuit, so correct temperatures will not be measured if a cold junction sensor from another Unit is used or if the two cold junction sensors in a Unit are swapped. Use the cold junction sensors as they are provided, without making any changes. • Always ground the GR terminal on the Power Supply Unit of the Controller. • If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground terminal. 10 CJ1W-PDC/PH41U/AD04U CJ1W-PTS51 Isolated-type Thermocouple Input Unit Overview The CJ1W-PTS51 Isolated-type Thermocouple Input Unit provides four direct thermocouple inputs, and sends the data to the CPU Unit each cycle.

If one of the cold junction sensors is disconnected, cold junction compensation will stop and correct measurement of temperatures cannot be made. Always make sure the cold junction sensors are connected when using the Units. • Cold junction sensors are calibrated separately for each Unit and connected circuit, so correct temperatures will not be measured if a cold junction sensor from another Unit is used or if the two cold junction sensors in a Unit are swapped. Use the cold junction sensors as they are provided, without making any changes. • Do not connect anything to NC terminals. Do not use NC terminals as relay terminals. • Always ground the GR terminal on the Power Supply Unit of the Controller. • If the input device uses a voltage generator, temperature compensator, or similar device, then ground the input device if it has a ground terminal. 15 CJ1W-PDC/PH41U/AD04U CJ1W-PTS52 Isolated-type Resistance Thermometer Input Unit (Pt100, JPt100) Overview The CJ1W-PTS52 Isolated-type Resistance Thermometer Input Unit provides four direct platinum resistance thermometer inputs, and sends the data to the CPU Unit each cycle.

Therefore, accuracy and resolution do not change even if a narrow input range is set. 22 CJ1W-PDC/PH41U/AD04U Terminal Block Diagram I1+ A2 Isolation circuit 250 Ω 1 MΩ B3 COM1 A/D converter 5 VDC Photocoupler Connector B2 Amplifier circuit V1+ 1 MΩ I2+ A4 Isolation circuit 250 Ω 1 MΩ B5 COM2 Amplifier circuit V2+ B4 A/D converter Input selector Digital circuits Photocoupler 1 MΩ A9 24-VDC circuit Power supply circuit B9 Terminal Connection Diagram Voltage Inputs + Voltage output device Voltage output device NC B1 (10) V1 B2 (11) − COM1 B3 (12) + V2 B4 (13) − COM2 B5 (14) NC B6 (15) NC B7 (16) NC B8 (17) 0V B9 (18) A1 (1) NC A2 (2) I1 A3 (3) NC A4 (4) I2 A5 (5) NC A6 (6) NC A7 (7) NC A8 (8) NC A9 (9) 24V A1 (1) NC Current inputs Current output device Current output device + − + − NC B1 (10) V1 B2 (11) COM1 B3 (12) V2 B4 (13) COM2 B5 (14) NC B6 (15) NC B7 (16) NC B8 (17) 0V B9 (18) A2 (2) I1 A3 (3) NC A4 (4) I2 A5 (5) NC A6 (6) NC A7 (7) NC A8 (8) NC A9 (9) 24V Note: 1.

The Unit may fail if a voltage input is wired incorrectly. Do not connect anything to terminals that are not being used. Do not connect anything to NC terminals. Do not use NC terminals as relay terminals. Wire the same lengths to A, B, and b so that the impedance will be the same. In particular, do not short circuit between B and b at the terminal block. 5. Always ground the GR terminal on the Power Supply Unit of the Controller. 6. If the input device uses a voltage generator, temperature compensator, or similar device, ground the input device if it has a ground terminal. 7. The cold junction compensators are individually calibrated for each Unit and each input circuit. If the terminal block from a different Unit is used, temperature measurements will not be accurate. Always use the terminal block that is delivered with the Unit. 27 CJ1W-PDC/PH41U/AD04U CJ1W-PH41U Isolated-type Universal Input Unit Overview The CJ1W-PH41U Isolated-type Universal Input Unit supports four input channels, each of which can be set to a resistance thermometer, thermocouple, DC signal, or potentiometer input.

When a disconnection occurs in the 4 to 20 mA/1 to 5 V range, the −15% process value is stored. When a disconnection occurs in any other range, a process value the same as for a 0 V input is stored. 0 to 20 mA inputs: An error is detected and the Input Error Flag turns ON when 115% of the measurable input range is exceeded. When a disconnection occurs, a process value the same as for a 0 mA input is stored. −1.25 to 1.25 V, −5 to 5 V, −10 to 10 V, ±10 V user-set range inputs: An error is detected and the Input Error Flag turns ON when 107.5% or −7.5% of the measurable input range is exceeded. When a disconnection occurs, a process value the same as for a 0 V input is stored. Process value alarm Four process value alarms (HH, H, LL, L), hysteresis, and ON/OFF-delay timer (0 to 60 s) can be set. Rate-of-change calculation Calculates the amount of change per process value comparison time interval (Either 1 to 16 s or the conversion period can be set.) Rate-of-change alarm Two rate-of-change alarms (H, L), hysteresis, and ON/OFF-delay timer (0 to 60 s) can be set (shared with process value alarm). Process value averaging (input filter) Calculates the moving average for the specified number of past process values (1 to 128), and stores that value in the CIO Area as the process value. When the process value scaling maximum value is A and the minimum value is B: Output = Square root extraction Function (A − B) × (input − B) + B Dropout: Output approx. 7% maximum linear (output = input) characteristics Note: 1. The square root function is enabled for DC inputs only. It is not performed for temperature inputs. 2. The square root function is enabled only when the maximum scaling value is greater than the minimum value. It is not performed when the minimum value is greater. 3. When performing square root calculation, set the maximum and minimum scaling values to the scaling values following square root extraction of the flowrate or other input value. Adjustment period control When zero/span adjustment is executed, the date is internally recorded at the Unit. When the preset zero/span adjustment period and the notice of days remaining set in the Expansion Setting Area have elapsed, this function turns ON a warning flag to give notice that it is time for readjustment. Peak and bottom detection Detects the maximum (peak) and minimum (bottom) process values, from when the Hold Start Bit (output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF. These values are stored as the peak and bottom values in the Expansion Control/Monitor Area. Top and valley detection This function detects the top and valley values for process values, from when the Hold Start Bit (output) allocated to the Expansion Control/Monitor Area turns ON until it turns OFF. These values are stored as the top and valley values in the Expansion Control/Monitor Area. Integral value calculation This function calculates the process value's time integral. The integral value is calculated and the result is output to the Expansion Control/Monitor Area when the Integral Value Calculation Start Bit in the Expansion Control/Monitor Area is turned ON. Cold junction compensation method Specifies whether cold junction compensation is to be executed internally or externally. Note: This function is supported only for thermocouple inputs.

When wiring voltage inputs, be careful not to connect the wrong terminals. Incorrect wiring may damage the Unit. 2. Do not remove the cold junction sensors that are connected to the CJ+ and CJ− terminals. If they are removed, compensation will not be executed and temperatures will not be correctly measured. 3. Use the cold junction sensors that are included with the product. Cold junction sensors are calibrated for particular Units and connection circuits. If a sensor from another Unit is used, temperatures cannot be correctly measured. 4. Use shielded cable when the resolution selection is set to 2 (1/16,000). 5. Use the same wiring length for connecting to A, B, a, and b, so that the impedance will be the same. In particular (for resistance thermometers), do not connect the A-a and B-b terminals. 6. Do not connect anything to unused terminals. 7. Be sure to ground the GR terminal at the Power Supply Unit for the Controller. 8. Be sure to ground all input devices (such as voltage generators, temperature calibrators, and resistors) that have ground terminals. 9. Do not mount an Isolated-type Universal Input Unit on the same CPU Rack or the same Expansion Rack as a CJ1W-OC@@@ Contact Output Unit. The Universal Input Unit measures process values at high resolution, and the noise that is generated from relay output switching can adversely affect these operations. 10.If the CPU Rack and an Expansion Rack are lined up horizontally on the control panel and a Relay Output Unit is mounted in the same Rack as the CJ1W-PH41U, keep the Racks separated by at least 70 mm. 11.If for some reason it is not possible to avoid mounting them on the same Rack, then mount them as far apart as possible and take measures such as installing a surge suppressor in the relay output circuit wiring. 36 CJ1W-PDC/PH41U/AD04U Nomenclature and Functions (Side View) Model Number RUN ERC ERH Unit number switch Terminal Block PTS51 B1 A1 MACH No. ×101 0 ×10 Unit mounting hook Fastening screws (M3 screws) Lock lever Front Panel LED Indicators CJ1W-PTS5@ ALM 1 - 2 - 3 - 4 RUN ERC ERH LED RUN (green) Meaning Operating ERC (red) Error detected by Unit ERH (red) Error in the CPU Unit ALM1 to ALM4 (yellow) External alarm outputs Indicator Operating status Lit Operating normally.
