The Omron 61F-GP-N8 220VAC is a High/Low level controller from the 61F series, designed to monitor and control liquid levels in tanks, reservoirs, or process vessels. It operates on a 220VAC supply and provides relay output via a SPDT (2 Form C) contact rated at 3A @ 250VAC. Sensitivity is adjustable from 0 to 4kOhm, and the control-to-sensor distance can reach up to 1km, making it suitable for remote tank farms or large storage facilities.
The 0 ~ 4kOhm sensitivity range covers most conductive liquids (water, mild chemicals, wastewater) when used with Omron 61F-series electrodes. The 1km maximum distance between controller and sensor allows the unit to be mounted in a central panel while electrodes sit at a remote tank — useful for large sites where running 220VAC to the tank is impractical. The SPDT relay switches a 3A resistive load at 250VAC, which is enough to drive a small pump contactor or alarm directly.
Integration Notes
Mounts via an 8-pin octal socket (sold separately). The plug-in termination makes swap-out fast — pull the old unit, plug in the replacement, no rewiring.
