SSAC-SYMCOM TDR4A23 Time Delay Relay
Brand: Littelfuse
Part Number: TDR4A23
Littelfuse Time Delay Relay, Series: TDR, 120 VAC, 1/3 hp, 8 Pins, DPDT, 50 ms, LED, -4 to 140 deg F, Plug-In/Socket Mount, 3.2 in L x 2.39 in W x 1.78 in H
Additional Description: LTFS-TDR4A23 SOLID STATE ON/OFF TIMER
Catalog Description: The TDR Series of time-delay relays are comprised of digital circuitry and an isolated, 10A relay output. The ON and OFF delays are selected by means of two, ten position binary switches, which allow the setting of the desired delay to be precise every time. Operation (Recycling - ON Time First): Upon application of input voltage, the green LED glows, the output relay is energized, the red LED glows, and the T1 ON time begins. At the end of the ON time, the output de-energizes, the red LED turns OFF and the T2, OFF time begins. At the end of the OFF time, the output relay energizes and the cycle repeats as long as input voltage is applied. Reset: Removing input voltage resets the output and time delays, and returns the sequence to the first delay. Operation (Recycling - OFF Time First): Upon application of input voltage, the green LED glows, the T1 OFF time begins, the load is OFF. At the end of the OFF time, the T2 ON time begins, the load energizes, and the red LED glows. At the end
