The current monitoring relays CM-SRS.2 are designed for use in single-phase AC and/or DC systems for over- or undercurrent monitoring. The devices are available with different supply voltage ranges, provide an adjustable tripping delay and work according to the open-circuit principle. Operating mode The CM-SRS.2 with 2 c/o (SPDT) contacts are available in 2 versions with 3 measuring ranges: 3-30 mA, 10-100 mA, monitored wire to the corresponding terminal B1/B2/B3-C. The units are adjusted with front-face operating controls. The selection of over- b or undercurrent monitoring a is made with a DIP switch. Potentiometers, with direct reading scale, allow the adjustment of the threshold value I, the hysteresis % and the tripping delay T V. The hysteresis % is adjustable within a range of 3 to 30 % of the threshold value and the tripping delay T V over a range of instantaneous to a 30 s delay. Timing is displayed by a flashing green LED labelled U/T.

Data sheet | Current monitoring relays CM-SRS.2 - 5 Function diagrams Overcurrent monitoring b The current to be monitored (measured value) is applied to terminals B1/B2/B3-C. The control supply voltage applied to terminals A1-A2 is displayed by the glowing green LED. If the measured value exceeds the adjusted threshold value, the tripping delay T V starts and the red LED (overcurrent) glows. Timing of T V is displayed by the flashing W green LED. When T V is complete and the measured value still exceeds the threshold value minus the adjusted hysteresis, the output relays energize and the yellow LED (relay energized) glows. If the measured value decreases below the threshold value minus the adjusted hysteresis, the output relays de-energize and the red and yellow LEDs turn off.

When T V is complete and the measured value is still below the threshold value plus the adjusted hysteresis, the output relays energize and the yellow LED (relay energized) glows.
