Binary Inputs; Signalling Outputs - ABB REG316 4 Series Operating Instructions Manual

REG 316*4 1MRB520049-Uen / Rev. F
3.2.2.

Binary inputs

(see Section 5.5.4.4.)
REG 316*4 recognises one of the following values:
logical "0" (fixed value) = FALSE
·
logical "1" (fixed value) = TRUE
·
binary input values (316DB6.)
·
binary control and protection values as defined by the
·
function number and the corresponding output signal
· binary value from the station control level.
· binary values from the distributed input units (500RIO11)
· binary values with interlocking data
All the above can also be set as binary inputs of control protec-
tion functions.
All the binary addresses set may be used either directly or in-
verted.
3.2.3.

Signalling outputs

(see Section 5.5.4.2.)
All the control and protection output signals provide the following
facilities:
· external signalling via LED's
· external signalling via relays
· event recording
· control of tripping relays
· external signalling via the communications interface
· external signalling via distributed output units (500RIO11)
· output of interlocking data
The following applies to external signals via a signalling relay or
a LED:
A signalling relay or LED can only be activated by one signal.
·
Every signalling relay and LED can be individually set to a
·
latching mode.
A signal can activate a maximum of two signalling outputs:
2 signalling relays
·
1 signalling relay and a LED
·
1 signalling relay and 1 tripping relay.
·
An output each can also be configured for the communication
interface, the distributed output units, interlocking data and event
recording.
Important signals are duplicated, e.g. 'GeneralTrip' and 'General
TripAux'.
