Description
Product details:
The digitised measured variables derived from the primary system quantities are continuously compared by the processing unit 216VC62a with the pick-up settings of the protection functions. If a protection function picks up, the corresponding signal or tripping command is transmitted via the B448C bus to the 216AB61 O/P unit resp. to the 216DB61 I/O unit. The allocation of the signals and tripping commands at the O/P’s of the protection functions to the various channels of the 216AB61 output unit or of the 216DB61 I/P signal and tripping unit is also determined by the software installed in the 216VC62a processor unit.
216VC62A
The output signals from the 216AB61 unit (signalling channels) and 216DB61 unit (trip channels) control the auxiliary relays K1…K16 of the 216GA61 O/P relay unit or 216GA62 tripping relay unit. The auxiliary relays’ contacts are potentially-free and wired to terminals for connection to external signalling and tripping circuits.
