Time Delay Relays Dedicated - Interval TDI / TDIH / TDIL SERIES Description The TDI Series is an interval timer that combines accurate digital circuitry with isolated, 10A rated, DPDT relay contacts in an 8-pin plug-in package. The TDI Series features DIP switch selectable time delays ranging from 0.1 to 10,230 seconds in three ranges. The TDI Series is the product of choice for custom control panel and OEM designers. Operation (Interval) Upon application of input voltage, the time delay begins. The output relay is energized during the time delay. At the end of the time delay, the output de-energizes and remains de-energized until input voltage is removed. 8-PIN Reset: Removing input voltage resets the time delay and the output. Features & Benefits Wiring Diagram FEATURES BENEFITS Repeat Accuracy + / - 0.1%, Digital circuitry Setting accuracy + / - 2% Isolated, 10A, DPDT Allows control of loads for AC or DC voltages output contacts Relay contacts are DIP switch adjustment Provides first time setting accuracy isolated.
