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. The three-digit LED display will time Up from the Time Preset.
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.
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.
Instantaneous and Delayed Relay Versions
425 comes with one set of SPDT instantaneous contacts and one set of SPDT delayed contacts.
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
Caution
Be advised that the relay(s) will transfer when setting knobs are adjusted to 000 when power is applied.
