Product Details
CM-SFS Current Monitoring Relay, 1-phase AC/DC
The current window monitoring relays CM-SFS.2 can be used for the simultaneous monitoring of over- and under-currents in single-phase AC and/or DC systems. The two c/o contacts can be configured to operate together (DPCO) or independently (2x SPCO) for over- and/or under-current conditions..
The current to be monitored (measured value) is applied to terminals B1/B2/B3-C. Open- or closed-circuit principle as well as an adjustable ON A or OFF tripping delay are configurable.
Monitoring of DC- and AC-currents: CM-SFS.21: 3mA - 1 A and CM-SFS.22: 0.3-15A
RMS measuring principle
One device includes 3 measuring ranges
Over- and/or undercurrent monitoring
ON-or OFF-delay configurable
Open- or closed circuit principle configurable
Latching function configurable
Thresholds for Imin and Imax adjustable
Fixed hysteresis of 5%
Start-up delay TS adjustable 0; 0.1-30s
Tripping delay TV adjustable 0; 0.1-30s
1x2 c/o contacts (common signal) or 2x1 c/o contact (separate signals for Imin and Imax)
22.5mm width
3 LED's for status indication
