Description
The SPA BUS interface is always available. The LON and MVB
protocols are transferred by PC cards.
The supply to the memory in the 216VC62a is maintained in the
event of an interruption by a gold condenser so that the event list
and disturbance recorder data remain intact. The disturbance
recorder data can be read via either the interface on the front of
the 216VC62a or the object bus. The data can be evaluated
using the “EVECOM” evaluation program. The internal clock of
the RE. 216 can be synchronised via the object bus interface of
SMS/SCS systems or by a radio clock.
I/P signals (channels) from the B448C bus:
digitised measured variables: primary system currents and
voltages
logic signals: external I/P signals
24 V auxiliary supply and data exchange with the B448C bus.
O/P signals (channels) to the B448C bus:
signal O/P’s from the protection and logic functions selected
tripping O/P’s from the protection and logic functions selected
data exchange with the B448C bus.
The designation of the I/O channels is identical to that of the I/O
unit (see Table 2.1).
