The ATC Diversified TSD-120-ARC-4H is a solid-state delay-on-break (off-delay) timer module for 120 V AC. Its delay is adjustable from 2.4 minutes to 4 hours with an external resistor across its RT terminals.
Supply voltage is applied continuously. Closing the control switch energizes the output relay; opening it starts the delay, and at the end of the delay the relay de-energizes. Re-closing the switch during the delay resets it.
Output: 1A SPST-NO. It has no LED indicator. Repeat accuracy: 1% maximum, no first cycle effect. Setting accuracy: Maximum setting ±10%, minimum setting +0%/-20%. Supply tolerance: ±10% of nominal; 50/60 Hz.
It is surface mounted and has 0.250 in (6.3 mm) male quick-connect terminals. It operates from 0 to +55 °C and stores from -45 to +85 °C. Approvals: UL Recognized, cUL Recognized (E55826).
