The ET Timer electronic time-delay device from Dortronics Systems is powered by a 12- to 24-volt DC supply and provides an adjustable (one-60 second) time delayed DPDT-3 Amp dry contact output. The model can be triggered from either a normally open or a normally closed momentary dry contact or by switching the trigger input to the power source ground. A field-selectable jumper allows the timer to execute a single time cycle upon initial power up. Wiring terminals are provided for connection of all field wiring. The timer, an expanded version of the company’s AT/FT time delay model, can be added as an option to many of the company’s push buttons, key switches and sounders. Dortronics Systems Inc.
