| Datasheet | Download Datasheet |
The Schneider Electric RM22LA32MR is a conductive liquid level control relay with 2C DPDT output and rated 8 A at 250 V AC; 2000 VA, driven by a 24 to 240 V AC/DC, 50/60 Hz input.
It controls the level of a conductive liquid, detection by resistive probes.
The setpoint covers 0.25 to 5 kΩ LS (Low Sensitivity), 5 to 100 kΩ St (Standard Sensitivity), 50 to 1000 kΩ HS (High Sensitivity) (adjustable 5 to 100%) between probe and common, so it is the conductivity of the liquid that decides the part.
The probes run on 12 V AC max, 1 mA max, and alternating current is what stops them electroplating away in service.
It has DIN Rail mounting and screw terminals.
