The 61F-GPN-BC supports automatic drainage when terminals 7 and 8 are open and automatic water supply when the terminals are shorted. Its SPST-NO relay output provides direct switching capability for compatible pumps, valves, contactors, and control circuits.

Power and detection circuits are isolated, allowing multiple controllers to operate within the same tank for multi-point level sensing. The included PFC-N8 hold-down clip helps secure the controller when installed with the compatible socket, supporting straightforward installation and maintenance.

Applications

The Omron 61F-GPN-BC is suitable for liquid level control in solar power generation systems, semiconductor wafer cleaning installations, remote locations without an AC power supply, and waste-heat recovery boilers in cogeneration systems. It can also support DC-powered control panels requiring automatic water supply or drainage control.

Typical uses include industrial automation systems, industrial control panels, machine control equipment, manufacturing equipment, OEM machinery, pump control systems, and maintenance projects involving compatible replacement parts. Correct socket, electrode, wiring, load, and operating conditions should be verified when integrating this controller with other automation components and electrical equipment.
