The Omron 61F-GP-ND AC200 is a conductive level controller for High/Low Level detection, running on a 200VAC supply. It uses a relay output (SPDT, 2 Form C) rated 3A at 250VAC, with adjustable sensitivity from 0 to 1.3kOhm — that range covers most water-based and light chemical conductive fluids. The 1km maximum distance between the controller and the remote sensor electrode gives you real placement flexibility across a tank farm or a multi-story process line.
Socketable — mates to an 11-pin octal base (standard industry pattern). Termination is plug-in, so a failed unit swaps in seconds without touching the panel wiring.
