The Omron H3CR-H8L DC48 S is an off-delay timer relay from the H3CR-H series, running on a 48 VDC supply. It switches a DPDT (2 Form C) contact set rated 5 A at 250 VAC, with an adjustable delay from 0.05 seconds up to 12 seconds set by the front hand dial.
The off-delay function means the relay coil must be continuously powered during the timing period; when power is removed, the delay starts, and the output contacts transfer after the set time. This is the standard configuration for sequenced shutdown or staggered stop applications on conveyors or fans. The 48 VDC coil is common in control panels with a DC bus, and the 5 A contact rating at 250 VAC covers most pilot-duty and small motor-starter loads. The socketable octal base (8-pin plug-in) lets you swap the timer in seconds without rewiring — a field-serviceable detail that keeps a line-down repair short.
