425A-300-Q-20-X-D

425A Series DIGITAL SETTING: The 425 is set digitally by rotating each setting knob until the desired Time Preset is displayed by the number wheels on the front of the timer. The digital setting allows exact, accurate and repeatable timing cycles. HIGH ACCURACY: The 425 utilizes a crystal controlled oscillator which provides 0.1% timing accuracy across all rated voltages and temperatures. CYCLE PROGRESS INDICATION: The 425 offers the industry’s brightest green LED display in a 1/16 DIN package. Depending on the Model, the three-digit LED display will time UP to or DOWN from the Time Preset. E48329 1/16 DIN HOUSING: The 48mm2 (1/16 DIN) housing is compact, allowing the 425 to be panel mounted or plug-in using an 8-pin octal socket. The decimal point and SEC/MIN/HRS switches are located on the side of the unit. When panel mounted, these range switches are not accessible to the operator. This Tamper-proof feature prevents unauthorized or hazardous changes to the timing range. 1/16 DIN LED Digital Display Timer • Easy-To-Read High Intensity Green LED Display • Timing From .01 SEC to 999 Hrs in One Unit MEMORY OPTION: The 425 can be ordered as standard with an EEPROM memory. This allows the 425 to retain the elapse time or time remaining during momentary or sustained power interruptions. • Switch Selectable Timing Ranges Are Tamper Proof When Panel Mounted INSTANTANEOUS AND DELAYED RELAY VERSIONS: A version of the 425 is available with one set of SPDT instantaneous contacts and one set of SPDT delayed contacts. • Time Preset Can Be Adjusted While Timing DELAYED RELAY VERSION: A version of the 425 is available with DPDT delayed contacts. MODEL 425A300G10XX (SPDT INSTANTANEOUS & SPDT DELAYED RELAYS): Timing starts when power is applied to terminals 2 and 7. The instantaneous relay energizes, the LED digital display begins to increment from 0 and the timing LED blinks slowly. When the preset value is reached, the LED blinks rapidly and the Delayed SPDT relay is energized. The timer remains in this timed-out condition until reset by removing power. MODEL 425A300G20XX (DPDT DELAYED RELAY): Timing starts when power is applied to terminals 2 and 7. The LED display begins to increment from 0 and the timing LED blinks slowly. When the preset value is reached, the LED stops, the timing LED blinks rapidly and the Delayed DPDT relay energizes. The timer remains in this timed-out condition until reset by removing power. MODEL 425A300G10MX & MODEL 425A300G20MX (MEMORY OPTION): Operation is same as above, however, units will not reset when power is removed during the timing cycle. Timers with this option can only be reset after time-out, or by adjusting the setting knobs to 000 during the timing cycle. CAUTION: Be advised that the relay(s) will transfer when setting knobs are adjusted to 000 when power is applied. • Timing LED Indicates Output Relay Status • EEPROM memory Option Standard Feature • Passes NEMA Showering Arc Noise Test • Panel Mounting or 8-pin Octal Plug-in mounting • Timing Up to or Down From the Set Point MODEL NUMBER MODEL NUMBER 425A 300 G RANGE 0 to 9.99 or 99.9 or 999 SEC,MIN,HR 300 VOLTAGE & FREQUENCY 120-240 VAC 50/60 Hz G OUTPUT ARRANGEMENT Instantaneous Relay (SPDT), Delay Relay (SPDT) Delay Relay (DPDT) 10 20 MEMORY Standard-No Memory With Memory (EEPROM X M FEATURES Standard (Time Up) X Standard (Time Down) D Special K ACCESSORIES 8-PIN 8-Pin surface/DIN rail socket Hold down clips for above socket Panel mounting bracket Plug-in socket kit (8-pin) 8-Pin socket w/rear facing terminals Automatic Timing & Controls 1/16 DIN TIMERS Through its internal micro controller, the 425 keeps track of the time setting by monitoring each of the three Time Preset switches. Whenever a change is made in the time preset, even during a cycle, the 425 instantly re-computes and adjusts the current timing cycle. 800.727.5646 000-825-85-00 407-025-13-00 405-320-02-00 319-261-45-00 000-825-90-00 automatictiming.com 37 8-6 8-5 425A Series Delayed 425A300Q20XX 425A300G10XX BEFORE START TIMING TIMED OUT O O X O = LOAD OFF X = LOAD ON RELAY Instantaneous Delayed 1/16 DIN TIMERS SPECIFICATIONS TYPICAL CIRCUITS RELAY Instantaneous Delayed CONTACTS 1-3 1-4 8-6 8-5 CONTACTS 1-3 1-4 8-6 8-5 Before Start Before Start During Timing During Timing End of Cycle End of Cycle 425A300G20XX O O X O = LOAD OFF X = LOAD ON Delayed CONTACTS 1-3 1-4 8-6 8-5 DIMENSIONS 38 RANGES Switch Selectable, 0 to 9.99,99.9 or 999 Sec/Min/Hrs LOAD RELAY TYPE LIFE CONTACT RATING ON-Delay Time Up ON-Delay Time Up ON-Delay Time Down ON-Delay Time Down G10 Models: SPDT, G20 Models: DPDT 10 Million operations (no load) 5 AMPS Resistive, 1/10 HP @ 120 VAC TEMPERATURE RATING 0° to 140°F (-18° to 60°C) NOISE IMMUNITY Showering ARC per NEMA ICS 2-230, the 425A will withstand a voltage surge of 4500 volts for 50 microseconds without damage MOUNTING 8-Pin Octal plug-in base, Panel Mounting Bracket POWER REQUIREMENTS 120 VAC, 50/60 Hz;(10%,-20%); 5 WATT maximum RESET TIME BEFORE START TIMING TIMED OUT Instantaneous 425A300G10XX 425A300G20XX 425A300G10XD 425A300G20XD REPEAT ACCURACY ± .1% over rated voltages 425A300Q20XX RELAY MODELS Before Start During Timing End of Cycle (INCHES/MILLIMETERS) Automatic Timing & Controls 100 mSEC minimum DISPLAY Cycle Progress Timing LED 3 Digit Green LED Display, seven segment numeric Red LED blinks slowly (once per second) during timing; blinks rapidly after time out.
