Physical & Electrical Parameters

System Backplane & Bus Isolation

The circuit card integrates a multi-layer board topology to sustain high backplane bus communication velocity across adjacent protection processing units. Solid-state isolation barriers decouple internal logic from field transients, ensuring firmware flash compatibility and deterministic logic routing across I/O expansion racks.

Standard Equipment Delivery

• 1 x ABB 1MRK000167-GCr00 circuit card
• 1 x Technical terminal mapping and installation document

Hardware Assembly & Wiring Protocols

• Rack Insertion

  Align the 6-layer board edges carefully with card guide rails and seat the rear connector firmly into the backplane bus socket.

• Cable Routing

  Separate 24 VDC digital I/O lines from high-voltage AC control circuits in panel channels to prevent EMI coupling.

• Earthing Connections

  Maintain rigid metal-to-metal grounding contact between the card front panel plate and the subrack chassis frame.

Technical FAQ
