TIME DELAY RELAY
74V w/ LED & 2x SPDT CONTACT
Part # 020-0097-00
The timer relay is a factory programmed device operated by a nominal 74 VDC control signal, it requires no secondary control power source. It contains two sets of form C contacts. An led indicator shows if the input voltage is present or the unit is in timing mode. The timing accuracy is controlled by a crystal controlled oscillator and software controlled counters for precise repeatable accuracy with virtually no drift.
VARIANT MODEL NUMBER
- 020-0111-00 : 120V/60Hz, DELAY 3sec ON, 6sec OFF w/ LED & 2x SPDT CONTACT
- 020-0131-00 : 24-74VDC, 1min T ON /w LED & 2x SPDT CONTACT

The nominally 74 Vdc wires are connected to the input terminals. When the power is applied the relay will take approximately 1 second to start up. The LED will indicate the status of the supply/control voltage. If the control voltage is present the relay will operate in accordance with the operation table supplied with your order. The LED will indicate as illustrated on your operation table. The illustration on the cabinet shows the contacts in the de-energized position.
