Binary Outputs
Overview
The 7SR45 Argus Relay provides 2 or 4 binary outputs which can be configured to send commands to the
switchgear units and annunciations for remote signaling of the important events and status.
The binary output can be assigned to any available functions under OUTPUT CONFIG > OUTPUT MATRIX
menu.
Binary Output Configuration
In the default operating mode, binary outputs are self reset and remain energized until the triggering condi-
tion exists. If required, the binary outputs can be programmed to operate as hand reset.
NOTE

The binary output 1 and binary output 2 only can be configured as hand reset. The binary output 3 and
binary output 4 are always of self reset type. The minimum operating time is 20 ms.
For 7SR450[1/3]-xGA10-1AA0
In the default operating mode, binary outputs are self reset. If required, the outputs can be programmed to
operate as hand reset. However, the hand reset functionality is applicable for protection trip signals, IRF
signal, and BI signals only.
All the supervisory signals such as low battery, general pick up, and protection healthy are always of self reset
type.
By default, the binary output 1 is mapped to IRF function and programmed as hand reset. In the self reset
condition, the binary output resets if the input current drops below the sensitivity levels.
NOTE

In the absence of auxiliary voltage, the binary output 3 and binary output 4 will not be functional and
remain in the non-operated condition.
