Time Delay Relays Multifunction TRU SERIES Knob Adjustable Universal Time Delay Relay Description The TRU Series is a multifunction, knob adjustable, Universal Time Delay Relay. It includes six of the most popular timing functions selected by a slide switch. The time delay is knob 8-PIN adjustable and the time delay range is switch selectable. The repeat accuracy is + 0.1%. Both function and time range can be selected on the top face of the unit. In addition to multifunctioning and multiple time ranges, the TRU Series features universal input voltage 19 to 264VAC and 19 to 30VDC and full 10A output relay. The TRU Series can directly replace up to 1000 competitive time delay relay models. 11-PIN Operation A six position slide switch selects delay-on-make, interval, single shot, recycling (ON time first, equal recycle delays), Wiring Diagram delay-on-break, and retriggerable single shot. 8-pin DPDT base wiring is limited to delay-on-make, interval, and recycling 8-PIN DPDT functions. All six functions are available in the 8-pin SPDT and Delay-on-Make 11-pin DPDT versions.
