TC-32 and TC-32-EXP USB/Ethernet-Based High-Precision Thermocouple Measurement Devices Features • USB and Ethernet interface • 32 differential thermocouple (TC) inputs with 24-bit resolution − Expandable to 64 TC inputs with TC-32-EXP expansion module − TC channel-to-host isolation A TC-32 connected to a TC-32-EXP device provides up to 64 TC inputs, 16 digital inputs, and 64 digital outputs which can be configured as alarms. All DIO channels are isolated. Overview The TC-32 and TC-32-EXP offer exceptional performance and accuracy for thermocouple (TC) measurement applications at a low cost per channel. Offering both Ethernet and USB ports, the TC-32 provides 32 channels of 24-bit resolution for medium channel installations. The TC-32-EXP adds 32 high-precision channels to support larger installations. − Easy-to-connect mini-jack connectors − 3 S/s per channel maximum sample rate − Cold-junction compensation (CJC) sensor per channel − Open thermocouple detection • 8 digital inputs and 32 digital outputs/alarms Accuracy is designed into the product with sigma-delta 24-bit ADCs, differential inputs, TC-to-host isolation and cold-junction compensation (CJC) for each channel to reduce the effects of thermal gradients. − Expandable to 16 digital inputs/64 digital outputs with TC-32-EXP expansion device With digital alarming notifications when a temperature exceeds programmed limits, the TC-32 and TC-32-EXP offer the perfect solution for temperature monitoring applications including server rooms, refrigerated storage, and long-run test cells − Isolated from TC inputs and host Channel Expansion with the TC-32-EXP Connect a TC-32-EXP expansion device to double the number of TC inputs (64), digital inputs (16), and digital outputs/ alarms (64). The TC-32-EXP connects to the host TC-32 through a 40-pin expansion connector. The host TC-32 provides all power to the TC-32-EXP The TC-32-EXP supports all of the TC input and digital I/O features of the host TC-32, including built-in cold-junction compensation and open thermocouple detection. USB or Ethernet Interface TC Input • 19” rack mountable Connect up to 32 differential TC input channels using the four groups of eight mini-jack connectors on the front panel of each device. • Requires external power (power adapter included with TC-32) Both the TC-32 and TC-32-EXP support a maximum sample rate of 3 S/s per channel, and TC types J, K, R, S, T, N, E, and B. TC types are software-selectable per channel. • Windows 11/10/8/7/ Vista® 32/64-bit • Linux® • Android™ Cold-Junction Compensation (CJC) Each TC input on TC-32 devices has a high-resolution CJC sensor that provides a local cold-junction temperature reference point. This feature ensures the highest level of temperature measurement accuracy. The TC-32 can communicate with a host device through either USB or 10/100 Ethernet. By offering both USB and Ethernet ports, the TC-32 is the perfect solution for local or remote monitoring. Measurement Computing − 50-pin header connector (cable sold separately) (508) 946-5100 Supported Operating Systems Data Linearization After the device performs CJC correction, an onboard microcontroller automatically linearizes the TC data using National Institute of Standards and Technology (NIST) linearization coefficients for the selected TC type. The data is then output as a 32-bit floating point value in the configured format (voltage or temperature). 1 info@mccdaq.com mccdaq.com TC-32 and TC-32-EXP Features Open-Thermocouple Detection (OTD) TC-32 devices are equipped with OTD for all TC input channels. When enabled, OTD allows users to monitor their TCs and determine if they are broken or disconnected. Connecting TCs to CommonMode Voltage Sources Thermocouple inputs are isolated and thermocouple common-mode voltage may deviate up to 48 VDC or 3.5 VAC (at 60 Hz) from chassis ground without any negative impact to measurement accuracy. Common-mode voltages between channels, however, should not vary more than ±1.4 VDC (refer to Common mode voltage range specifications on page 4 for more information). Digital I/O and Alarms The TC-32 provides up to 8 digital inputs and 32 digital outputs that are electrically isolated from the host device and from the TC-32 analog circuits. This configuration allows users to optionally configure a digital output as an alarm for each TC channel. When configured as an alarm, the digital output line is driven to the appropriate state determined by the alarm options and input temperature. Users can also use the alarm outputs to control a device or application that indicates: The TC-32 can connect to an Ethernet or USB port. Both the TC-32 and TC-32-EXP include 50-pin connectors that provide access to all DIO channels. Adding the TC-32-EXP expansion device doubles the channel count of the system. Alarm Input Modes lowing alarm error modes: Users can set independent temperature thresholds T1 and T2 for each alarm and enable one of the the following alarm input modes: • Alarm disabled; digital output line can be used for normal operation • Trigger alarm when input temperature ≥ T1; reset alarm when input temperature < T2 Alarm enabled; active low output (output line goes low when alarm condition is met) • Trigger alarm when input temperature ≤ T1; reset alarm when input temperature > T2 Alarm enabled; active high output (output line goes high when alarm condition is met) • Alarm output may be latched and will not clear unless explicitly cleared by the user • • • Trigger alarm when input temperature is < T1 or > T2 Alarm Error Modes • when a software-selectable temperature threshold has been exceeded Users can set the conditions that trigger each alarm by selecting the following alarm error modes: • when an open TC has been detected • • when the common mode voltage is out of range Trigger alarm based on temperature reading only • Trigger alarm based on temperature reading, open thermocouple detected, or common-mode voltage error All alarm mode settings can be configured with InstaCal. • Trigger alarm based on open thermocouple detected or commonmode voltage out-of-range error only Alarm Output Modes Users can set the behavior of each digital/ alarm output by selecting one of the fol- Measurement Computing (508) 946-5100 2 Power The TC-32 requires external power. A 5 V, 10 W power adapter (PS-5V2AEPS) is included with the TC-32. The TC-32 provides power to the TC-32-EXP when they are connected. Calibration Both the TC-32 and TC-32-EXP are factory-calibrated using a NIST-traceable calibration process. Specifications are guaranteed for one year. For calibration beyond one year, return the device to the factory for recalibration. The TC-32 and TC-32-EXP devices also support field calibration so that users can calibrate a device locally. info@mccdaq.com mccdaq.com TC-32 and TC-32-EXP Software Software Support The TC-32 and TC-32-EXP are supported by the software in the table below.
