Binary Inputs
Overview of Functions
7SR5 devices include a number of binary input functions:
•
Binary inputs (number dependent on hardware configuration)
•
28 Virtual inputs/outputs
•
Function key binary inputs
•
20 General alarms
Binary inputs operate when the applied voltage exceeds the selected
Operate Voltage
setting. This setting
applies to all binary inputs.
Binary inputs can be configured for inverted operation i.e. the input is energized when no supply is applied.
Virtual inputs/outputs are internal logic states.
Function keys (
I
and
O
pushbuttons) are located on the device fascia.
Functionality of each binary input is configured in the
Configuration > Binary Inputs
menu.
Structure of the Function
The operating parameters for each voltage operated binary input are defined in the
Binary Inputs >
Binary Input Config
menu.
The operating voltage for all binary inputs is selected.
Each binary input can be individually configured to inverted operation and have operating pick up and drop off
delays.
The function of each binary input or virtual input/output (when operated) is set in the
Binary Inputs >
Input Matrix
menu. The input matrix defines the internal logic signals that are created by energization of
selected binary inputs.
The operating parameters for each function key are defined in the
Binary Inputs > Function Key
Config
menu.
The
General Alarms
menu allows the user to define the information displayed when a binary input is set as
a
General Alarm
.
Binary inputs correspond to the logical node
CTRL BIGGIO
in IEC 61850.
Virtual inputs/outputs correspond to the logical node
CTRL VGGIO
in IEC 61850.
