REB 670*1.0 Variants
12I + 3*IO Cards
3Ph, 4 bays, 2 zone Used for small, fixed zones like T protection, meshed corner, ring bus etc. Not Applicable 3Ph, 8 bays, 2 zone
12I/24I + 11*IO Cards
Not Applicable
A20
Used for small substations with up to 8 CT inputs. Complete zone selection & CBF protection! A31
1Ph, 12 bays, 2 zone (three IEDs required)
ABB Power Technologies AB, 2005
Used for substation with up to 12 CT inputs. No zone selection possible due to limited No. of IO cards. No extension possibilities! Good for stations with fixed zones (i.e. 1? breaker). B20 Not Applicable
Used for substation with up to 12 CT inputs. Possible to use zone selection & CBF. Possible to extend to 24 CT inputs
B21
Used for substation with up to 24 CT inputs. Possible to use zone selection & CBF, but possible application problems due to binary IO limitations.
1Ph, 24 bays, 2 zone (three IEDs required)
