The Omron 61F-GP-N8L-2KM AC240 is a high/low level controller from the 61F series, designed for liquid level detection in tanks, reservoirs, or process vessels. It operates on a 240VAC supply and provides a SPDT (2 Form C) relay output rated at 3A @ 250VAC, suitable for driving pumps, valves, or alarms based on sensed level. The sensitivity range of 0 ~ 1.3kOhm covers most conductive liquids — water, mild chemicals, or wastewater — and the maximum control-to-sensor distance of 2km means the controller can be located in a central panel while the electrode probes sit at a remote tank, per the datasheet.
Mounting and Termination
Socketable with an 8-pin octal base — the controller plugs into a standard relay socket (sold separately), making field replacement fast without rewiring. The termination style is plug-in, so the wiring stays on the socket when the unit is pulled for service.
