The Finder 72.11.8.240.0000 is a conductive liquid level control relay with 1C SPDT output and rated 16 A at 250 V AC, driven by a 230 to 240 VAC input.
It controls the level of a conductive liquid, pumping up or down to fill or drain the tank.
It controls about a single level with one probe, or between a high and a low probe, each against a common electrode; a metal tank can serve as the common.
The setpoint covers 150 kOhm (fixed) between probe and common, so it is the conductivity of the liquid that decides the part.
The probes run on 4 V AC, 0.2 mA, and alternating current is what stops them electroplating away in service.
Its run-on delay is 1 s fixed, so a ripple on the surface does not cycle the pump.
Its contacts are AgNi, switching loads down to 500 mW (10 V/5 mA).
It has DIN Rail mounting and box clamp terminals.
