Industrial Application Scenarios
The ABB 1MRK000173-BCR00 I/O daughter card is deployed inside low-voltage control bays, marshalling kiosks, and high-voltage substation switchgear cabinets.
Primary field uses include:
Substation Grid Monitoring: Interfacing with breaker auxiliary position switches to transmit open/close confirmation signals back to the main SCADA control room.
Process Interlocking Schemes: Collecting binary alarm strings from oil level, temperature, and pressure trip gauges on heavy transformer units, ensuring immediate protective action during critical faults.
Industrial Plant Automation: Serving as a high-reliability signaling block inside heavy industrial facilities (such as steel mills or paper plants) where standard commercial I/O blocks fail due to severe electromagnetic interference (EMI).
