The Omron 61F-GP-NT AC240 is a High/Low Level liquid level controller from the 61F series, operating on a 240VAC supply. It uses a relay output with SPDT (2 Form C) contacts rated at 3A @ 250VAC, and its sensitivity is adjustable from 0 to 4kΩ, with a maximum control-to-sensor distance of 600m.
Socketable mounting via an 8-pin octal base simplifies panel wiring and replacement. The plug-in termination style allows quick swap without disturbing field wiring, which is useful for MRO spares in a line-down scenario.
