The model 437D module is an in-line timing device that energizes a load circuit for a preset timing period each time that operating voltage is applied. Ease of installation permits the model
437D circuit. When a DC operating voltage is applied the 437D turn ON and the load current is permitted to flow. At the end of the delay period, the model 437D turns OFF and only leakage
current is permitted to flow. To recycle, remove the operating voltage for at least 50 milliseconds then re-apply.
