It operates on a 120VAC supply and switches a SPDT relay (2 Form C) rated at 3A at 250VAC. The sensitivity range of 0 to 4kOhm covers most conductive liquids — water, weak acids, coolants — where the resistance between probes drops below the set threshold. The 0 to 4kOhm sensitivity range is the core selection parameter. Set it to the actual resistance of your liquid at operating temperature — clean water is roughly 10-50 kOhm per cm, so this controller works with a probe spacing that keeps the loop resistance under 4 kOhm. The 600m maximum distance between controller and sensor means the electrode head can be placed far from the panel, useful for deep tanks or remote sumps. The SPDT relay output (2 Form C) at 3A/250VAC drives a small pump contactor or alarm directly. If your load exceeds 3A, interpose a power relay. The socketable octal base (8-pin plug-in) makes replacement a 30-second swap — no rewiring, which matters when a sump pump controller fails at 2 AM. The 61F-GP-NT AC120 mounts via its octal socket to a DIN rail or panel. The 8-pin plug-in termination matches standard relay sockets (e.g. Omron PYF-08A or equivalent).","metaTitle":"Omron 61F-GP-NT AC120 Level Controller, 120VAC, 0-4kOhm","metaDescription":"Omron 61F-GP-NT AC120 High/Low Level controller, 120VAC supply, 0-4kOhm sensitivity, SPDT relay output, 600m max sensor distance.
