Relays electromagnetic a direct current of the REV 800 series are used in schemes of automatic control as electromagnetic timers (REV 811 - REV 818, REV 880), control of current (REV 830), control of tension (REV 821, REV 825) and intermediate (REV 822, REV 826) including electric equipments of cars of the subway (REV 811T - REV 814T).

Contacts of the relay allow on the place of operation by simple reassembly of the same details it is not recommended to change execution of contacts within total 2 (1 "3" and 1 "Р") or 4 (2 "3" and 2 "Р") (application 4 "Р" contacts by plant since at the same time reliable functioning of the relay is not ensured).

Relays can be adjusted on retraction current within 30÷80 from rated current of the coil (tropical execution within 45÷80 of %).
