Industrial 405A500F2X Programmable Time Delay Relay

The ATC 405A500F2X is an industrial programmable time-delay relay from ATC’s 405 timer series, designed for on-delay and interval timing with a single DPDT output relay. It operates from a 120–250 VAC supply and can switch loads rated up to 10 A resistive at 30 VDC or 250 VAC, with motor load ratings of 1/8 HP at 120 VAC and 1/4 HP at 240 VAC (240 VA at 240 VAC). Timing ranges are selectable as 5 or 50 units across seconds, minutes, or hours depending on the variant, enabling both short and longer delays within automation sequences. This makes the device suitable for start/stop sequencing of conveyors, pumps, and other electromechanical equipment, as well as interlock or timing control in control panels. With a DPDT contact arrangement, the 405A500F2X can independently control two circuits from a single timer channel, enabling coordinated timing actions such as staggered device enablement or defined interlocks between processes. Rugged and compact, the timer is intended for industrial control applications where precise timing and reliable relay operation are required.
