Liquid Level Control with High/Low Detection
The Omron 61F-GP-N2 240 is a liquid level controller that uses the conductivity of the liquid to detect high and low levels via probe electrodes, with a sensitivity range of 0 to 4 kOhm. This means it can be adjusted to trigger at the specific resistance of the process liquid—clean water triggers at a lower resistance than, say, a chemical solution. The 240VAC supply powers the control circuit directly, so no separate control transformer is needed in the panel for this function. Termination is via a standard 8-pin octal plug, which mates with a socket base—common in panel layouts for quick replacement without rewiring the enclosure.
Socketable Mounting and Panel Integration
Socketable mounting means the controller plugs into a pre-wired socket, typically a DIN-rail or panel-mount octal base. This is the standard form factor for level relays in industrial water treatment, boiler feed, and tank overflow prevention panels. When the controller needs service, pull the unit and plug a spare in—no terminal screwdriver needed. The 8-pin octal pinout is industry-standard, so the socket footprint matches existing panel cutouts or DIN-rail terminal blocks with octal sockets.
It remains a current catalog item in the Omron 61F series, not an end-of-life or NRND part. No last-time-buy or obsolescence concerns apply to this order code.
