Siemens 7SR51 - 3.4 Binary Inputs

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.
