The Omron 61F-G2P-AC200 is a High/Low Level liquid level controller from the 61F series, operating on a 200VAC supply. It uses two relay outputs — one SPST-NO (1 Form A) and one SPDT (1 Form C) — to signal high and low alarm conditions, with an adjustable sensitivity range of 0 to 4 kOhm for detecting conductive liquids.
The 5A contact rating at 200VAC directly switches a small pump contactor or alarm beacon. The 1 km maximum distance between controller and sensor allows remote tank monitoring. Socketable mounting with a 15-pin octal plug enables quick replacement without rewiring.
No official successor has been issued, and the 61F series remains the current-generation platform for Omron conductive level control.
