This RCR module is to be built into a single phase electricity meter ZE110. with a standard optical interface. It comprises a printed circuit board with output relays and is covered together with the meter. K2 and K3 relay contacts (with switching current of up to 8 A) are led to terminals that are accessible only after removing the terminal box cover. K1 and K4 relays used for switching the meter rates are optron based.
Both the contact programming connector and selftest button are accessible only after removing the meter cover. The module is completely (except for the power supply) galvanically separated from the meter.
