Binary Inputs
Overview
The binary inputs (BI) are optocouplers operated from a suitably rated AC/DC power supply.
There are 2 ordering options available based on the operating threshold of binary inputs.
•
Binary input with an operating threshold of 88 V. Works on both AC and DC voltage supply
•
Binary input with an operating threshold of 19 V. Works on purely DC voltage supply
The status of BI can be viewed via LCD or Reydisp Evolution software or SCADA.
The 7SR46 Argus Relays are available with 2 binary inputs. You can assign any binary input to any of the avail-
able functions such as inhibits, binary outputs, reset flags, and general alarms under INPUT CONFIG > INPUT
MATRIX. The binary input can also be mapped to operate the pulse output in the presence of auxiliary power
supply/CT input.
Pickup (PU) and Dropoff (DO) time delays are associated with each binary input. When no pickup delay is
applied, then input will pick up due to induced AC voltage on the wiring connections (for example, cross site
wiring).
Each input can be configured independently. Each input can be logically inverted to facilitate integration of
the relay within the user scheme. When inverted, the relay indicates that the BI is triggered when no binary
input voltage is applied. Inversion occurs before the PU and DO time delay.
Binary inputs can be configured for instantaneous operation from DC 19 V power supply, by setting the pickup
timer to 0 ms and the dropout timer to 25 ms.
Each binary input can be assigned to any binary output and this allows the relay to provide panel indications
and alarms.
