Catalog Description CM-SRS.M1S Current monitoring relay 2c/o, B-C=3mA-1A RMS, 24-240VAC/DC
The CM-SRS.M1S is a multifunctional current monitoring relay from the CM single-phase
monitors range. This monitoring relay operates with a rated control supply voltage of 24 -
240 V AC / DC and has a 2 c/o (SPDT) output with contacts rated at 250 V / 4 A. It provides
a RMS measuring principle for DC and AC currents with 3 measuring ranges: 3-30 mA, 10-
100 mA and 0.1-1 A. The CM-SRS.M1S offers selection of over- or undercurrent monitoring,
Long Description open- or closed-circuit operating principle, with or without latching function. The hysteresis is
adjustable within a range of 3 to 30 % of the threshold value. The tripping delay and the start
-up delay are adjustable over a range of instantaneous to 30 s (0, 0.1-30 s). A sealable
transparent cover for protection against unauthorized changes is available as accessory.
The device offers screw connection technology with double-chamber cage connection
terminals.
