Time Delay Relays SINGLE SHOT * TDS / TDSH / TDSL Series Relay Output, Single Shot Time Delay Relay Description The TDS series combines accurate digital circuitry with isolated, 8 A rated, DPDT or SPDT relay contacts in an 8-pin or 11-pin plug-in package. The TDS series features DIP switch selectable time delays ranging from 0.1s to 10,230 s in three ranges. The TDS series is the product of choice for custom control panel and OEM designers. Operation (Single Shot) Input voltage must be applied to the input before and during timing. Upon momentary or maintained closure of the initiate switch (leading edge triggered), the output relay energizes for a measured interval of time. At the end of the delay, the output de-energizes. Opening or reclosing the initiate switch during timing has no affect on the time delay. The output will energize if the initiate switch is closed when input voltage is Wiring Diagram applied. Reset: Reset occurs when the time delay is complete and the initiate switch is opened. Loss of input voltage resets the time delay and output. 8-PIN OCTAL SPDT Features & Benefits FEATURES BENEFITS 3 time ranges available Makes it versatile for use in many L1 N/L2 (0.1 s to 2.8 h) applications S1 = Initiate Switch Repeat Accuracy + / - 0.1 % Microcontroller based Relay contacts are isolated.
