The Omron H5CN-XBN DC12-48 is an on-delay timer relay from the H5CN series, switching a SPDT (1 Form C) contact rated at 3A @ 250VAC. It accepts a 12-48VDC supply and covers a delay range from 0.001 to 99.99 seconds, set via up/down digit keys. This is a socketable, mechanical relay with an octal (8-pin) plug-in termination — mounts into a standard 8-pin octal relay socket, which is a common panel layout. The timing initiate method is input voltage: applying the DC supply starts the delay cycle.
The 3A contact rating at 250VAC covers typical control-circuit loads — pilot lights, contactor coils, small solenoid valves. The 0.001-99.99s range with digital keypad adjustment gives precise repeatability for timing sequences like conveyor staging or pump alternation.
