The TTD product is a solid-state fault annunciator and shut-down control system designed to protect engines, pumps, compressors and associated equipment.
The TTD model accepts 48 sensor inputs from normally open and/or normally closed sensors. Each of the 48 inputs can be configured for shutdown or alarm only. Any input can be locked out by one of the two start-run timers or configured as Class C, ESD or ignore. The annunciator provides for both closing of a fuel valve and grounding of an ignition after a time delay.
