A Pre-assembled adjustable Pulse Timer with dual changeover relay output. Ideal for intermittent operation of equipment.The relay has dual 5 Amp changeover contacts. Working voltage is 9v to 18v DCPulse time is adjustable from 1 seconds to 8 seconds, Pause time is adjustable from 2 seconds to 60 seconds.
This is a Pulse timer, also known as a bistable timer. When the timer is triggered by applying power to +- 12v terminals the timer will switch ON & OFF (pulse). The ON time is set by VR2, the OFF time is set by VR1. This pulsing will continue until power is removed from +- 12v terminals.Basic operation:
The timer is started by applying power to the +- terminals as shown in the drawing below. The pulsing ON/OFF will continue until the power is removed. Adjustment of the pulse is as follows. To increase the OFF time turn the Variable Resistor VR1 to the right (clockwise), to increase the ON time turn the variable resistor VR2 to the left (anticlockwise). The output relay will be energised during the ON period (pulse). The relay has two sets of changeover contacts, this means that in the OFF (pause) state there is a circuit between the COM and NC terminals, and in the ON (pulse) state there is a circuit between the COM and NO terminals. The Green LED behind the Variables will indicate when the timer is in the PULSE state and will be Off during the PAUSE state, use this indication to set the timerPossible applications include Blinking lights, single frame photo shooting, lighthouse beacon, rail crossing lights or sounder, pedestrian crossing lights or sounder
