Purpose designed to convert almost any engine control systems from energise to run into Energise to Stop. It also provides a seperate 1 sec Pulse output for dual coil stop solenoids. The interval timer is triggerred by the loss of the energise to run (Fuel Solenoid) supply and remains energised for a preset time. For 12 or 24V operation, simply replace the automotive relays with those of the correct voltage. Screw Clamp Terminals and resin encapsulation provides high resistance to vibration, humidity and handling.
