The Omron H5CN-YAN AC100-240 is a panel-mount on-delay timer relay from the H5CN series, socketable onto an 8-pin octal base. It provides a single SPDT (1 Form C) output rated at 3 A at 250 VAC, with a delay range of 0.001 to 9.999 seconds set via up/down digit keys. Supply voltage is 100 to 240 VAC, making it a drop-in replacement for existing octal-base timers in control panels without rewiring the socket.
The 3 A at 250 VAC SPDT contact rating covers pilot duty, relay coils, contactor coils, and signal lamps in typical control circuits. It is not sized for motor loads or heater banks — those belong on a separate contactor. The 0.001 to 9.999 second range with digital setting gives repeatable timing for short-cycle sequences like conveyor interlock delays, pump alternation, or compressor unload timers. The 100-240 VAC supply covers common line voltages globally without a separate control transformer.
Socketable design with an 8-pin octal base — mates to standard Omron PTF08A or equivalent sockets. Termination is plug-in, so replacement takes seconds without rewiring. Timing initiate method is input voltage: apply supply to start the delay, remove it to reset.
