The Omron 61F-GP-N AC240 is a High/Low Level controller from the 61F series, designed for conductive liquid level detection and control in tanks, reservoirs, and process vessels. It operates on a 240VAC supply and uses a relay output with SPDT (2 Form C) contacts rated at 3A @ 250VAC, making it suitable for driving pumps, valves, or alarms directly. The sensitivity range of 0 to 4 kOhm allows the unit to detect liquids with varying conductivity—from relatively pure water to more conductive process fluids—by sensing the resistance between probe electrodes. The control-to-sensor distance of up to 1 km means the controller can be sited remotely from the tank, useful for centralizing control panels in large plants.
Mounting and Termination
Socketable mounting via an 11-pin octal plug (termination style Plug In, 11 Pin (Octal)) means the controller can be swapped without rewiring—critical for MRO spares on a production line. The socket (ordered separately) mounts to a panel or DIN rail; the controller simply plugs in. This form factor is standard across the 61F family, so a replacement unit fits the existing socket and wiring.
Sourcing and Availability
As an active Omron 61F series product, the 61F-GP-N AC240 is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time, with no minimum order restrictions typical for this class of socketable level relay. For volume commitments or blanket orders, the global supply-demand balance for the 61F platform remains stable given its mature installed base in water/wastewater and process industries.
