May inputs on a MiCOM Px20 relay be assigned to outputs?
Issue
Users need to know whether digital inputs on a MiCOM Px20 relay can be directly linked or assigned to output contacts for control or tripping purposes.
Product
MiCOM Px20
Environment
Protection relay configuration and automation control settings within MiCOM Px20 relays.
Cause
Uncertainty in configuring the relay logic to allow digital inputs to drive output contacts or initiate tripping functions.
Resolution
Yes, the inputs can be assigned to outputs. Inputs may be directly linked to a trip contact or assigned through intermediary logic such as a 52A/52B breaker status contact and programmed accordingly.
To configure this:
- Navigate to the Automation Control section in the relay settings.
- Locate the Inputs configuration submenu.
- Assign the desired input signals to the corresponding outputs or logic functions as required.
