CM-SRS Current Monitoring, Single Phase AC/DC Depending on the configuration, the current monitoring relays CM-SRS.1 and CM-SRS.2 can be used for over- or undercurrent monitoring in single-phase AC and/or DC systems. The current to be monitored (measured value) is applied to terminals B1/B2/B3-C. The devices work according the open-circuit principle. If the measured value exceeds resp. drops below the adjusted threshold value, the output relay(s) energize(s): on the CM-SRS.1 immediately, on the CM-SRS.2 after the set tripping delay TV. Monitoring of DC- and AC-currents: CM-SRS.x1: 3mA - 1A and CM-SRS.x2: 0.3-15A RMS measuring principle One device includes 3 measuring ranges Over- or undercurrent monitoring configurable Hysteresis adjustable from 3-30% Tripping delay TV adjustable 0.1-30s CM-SRS.1: 1 c/o contact CM-SRS.2: 2 c/o contacts 22.5mm width 3 LED's for status indication

DIB01CD4810A, Carlo Gavazzi

The Carlo Gavazzi DIB01 is a precise TRMS AC/DC over or under current monitoring relays. Direct measuring or through current transformer. Owing to the built-in latch function, the ON-position of the relay output can be maintained. Inhibit function can be used to avoid relay operation when not desired. The LED's indicate the state of the alarm and the output relay. Through the built-in shunt it is possible to monitor loads up to 10 A AC/DC. Selection of measuring range by DIP-switches Measuring ranges from 0.1 mA to 10 A AC/DC Adjustable current on relative scale Adjustable hysteresis on relative scale Adjustable delay function (0.1 to 30 s)
