The Omron 61F-G3NR AC110/220 is a conductive level controller from the 61F series, designed for High/Low Level detection in tanks and reservoirs. It operates on a dual-rated 110/220VAC supply, making it usable across both 110 V and 220 V line voltages without a separate transformer tap. Three relay outputs (SPDT, 2 Form C) rated 3A @ 200VAC drive alarms or pump contactors directly. The sensitivity adjustment from 0 to 1.1 kOhm lets you tune the probe circuit for water, wastewater, or conductive process fluids — higher resistance settings handle distilled or low-conductivity liquids. Control-to-sensor distance reaches 800 m, so the controller can sit in a panel remote from the tank. Screw terminals and DIN-rail mounting simplify panel integration — no special bracket or enclosure cutout needed.
