ATC Diversified Electronics TDF-120-AKA-010 Time Delay Relay

ATC Diversified Electronics TDF-120-AKA-010 Time Delay Relay is an off-delay timer with a DPDT (2 Form C) contact arrangement that completes its timing cycle after a user-set 0.1 to 10 second interval. It operates from a 120 V AC or DC supply and can switch up to 10 A at 250 VAC or 24 VDC, making it suitable for sequencing motors, solenoids, and other loads in control panels. The unit uses an 8-pin octal plug-in socket and features a knob-adjustable front dial to set the delay precisely within the standard range. Timing begins when input voltage is applied; after the selected delay, the relay energizes, and a reset is achieved by removing power. The TDF-120-AKA-010 is part of ATC Diversified Electronics’ time-delay lineup and is commonly used for simple delayed-on or sequencing functions in industrial equipment, offering a compact, plug-in solution with robust switching capability for 120 VAC/DC applications.
