Voltage monitoring relay REV-821 U3 48V DC IP00 ElektrotekhnikET513128

REV series relays are used in automatic control circuits as electromagnetic time relays (REV 811, 812, 813, 814, 815, 816, 817, 818), current monitoring (REV 830), voltage monitoring (REV 821, 825) and intermediate relays (REV 822, 826). - the relay contacts allow changing the contact configuration on-site within a total of 2 (1 "3" and 1 "R") or 4 (2 "3" and 2 "R"); - relays can be adjusted for pull-in current within 30-80% of the rated coil current.
