Control and measuring units are designed to be used as cubicle-oriented remote control interface units in switchgear. The units allow control signals for the circuit breakers, binary signals from the switchgear and analog signals from transducers and measuring trans-formers to be transmitted to the substation level system and further to the remote control system.
The binary signal inputs are used for reading status information from circuit breakers and disconnectors as well as start and alarm signals from the protection relays of the switchgear cubicle. Two of the binary signal inputs can be configured as pulse counter inputs, which can be used for reading energy meters with pulse outputs.
