ABB電流監控繼電器，具有雙雙刀觸頸，24 V至240 V交流/直流，1相1SVR730760R0400 CM-SFS.21S。 1SVR730760R0400 CM-SFS.21S

Feature

• 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
