The 1MRK000173-CC is a high-density Binary Input/Output (I/O) module designed for the ABB Relion® 670 and 650 series of protection and control relays (such as the REF670, RED670, and RET670). This module acts as the physical interface between the digital logic of the protection relay and the primary equipment in the substation. It is responsible for capturing status signals (e.g., circuit breaker position, isolator status) and executing control commands (e.g., trip or close signals). Built to meet stringent utility standards, it features high-speed operation and advanced filtering to prevent false signaling in high-EMI environments.

Application Fields
The 1MRK000173-CC is a core component in grid-scale protection architectures:
-
Circuit Breaker Control: Providing the high-speed “Trip” and “Close” contacts for substation breakers.
-
Status Supervision: Monitoring auxiliary contacts of isolators, earth switches, and gas pressure sensors (SF6).
-
Interlocking Logic: Transferring status information between different relays to prevent unsafe switching operations.
-
Alarm Signaling: Driving local annunciators and remote SCADA alarms in transmission-level substations.
Product Instructions
-
Safety: Before handling the module, ensure the IED (Intelligent Electronic Device) is powered down. Terminal blocks may carry hazardous DC station voltages even if the relay is off; verify with a voltmeter.
-
ESD Handling: This module contains sensitive CMOS components. Use a grounded ESD wrist strap and handle the PCB only by the edges or the plastic front-panel handles.
-
Threshold Jumper Setting: Before insertion, verify the physical jumpers on the board (if applicable to your revision) match the station battery voltage (e.g., 110V DC or 220V DC) to ensure correct input detection levels.
-
Installation: Slide the module into the designated slot in the Relion subrack. Ensure the card is perfectly aligned with the backplane connectors. Tighten the front-panel captive screws to ensure a solid electrical ground.
-
Configuration: Use ABB PCM600 software to map the physical I/O channels to the internal logic functions (e.g., mapping Input 1 to “CB Open”). Perform a “Forced I/O” test to verify wiring before going live.
Q&A – Frequently Asked Questions
Q: Can I use the 1MRK000173-CC in any Relion 670 relay? A: Yes, the Relion 670 series is modular. However, you must ensure the relay’s configuration file (MCD) is updated in PCM600 to recognize the new module in that specific slot.
Q: Why are my binary inputs not picking up despite voltage being present? A: This is often caused by a mismatch between the station voltage and the software/hardware threshold settings. If the threshold is set for 220V but your station is 110V, the input will not trigger.
Q: Does this module support high-speed tripping? A: Yes. The output contacts are designed for high-speed operation (typically < 8ms) and are reinforced to break inductive DC loads common in breaker trip coils.
Q: How do I distinguish between this and a purely Binary Input (BIM) module? A: The “CC” revision is a combined I/O module. Check the label: BIM modules only have inputs, while this 1MRK000173-CC features both inputs and outputs on a single card.
