CI626A 3BSE005023R1 | ABB | Control Board

The ABB CI626A 3BSE005023R1, also cataloged as the CI626A Control Board, operates as a dedicated hardware component for localized processing and multi-protocol data translation within System 800xA networks.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling

The control board features an integrated architecture to maintain backplane bus communication velocity across expanded sub-rack setups. The dual Ethernet and RS485 interfaces enable seamless linking with deterministic communication frames, permitting multi-point hardware configurations. Integrated logic blocks balance internal register mapping tasks during dense I/O density scaling routines, keeping processing cycle times stable and verifying firmware flash compatibility parameters against the master controller nodes.

Frequently Asked Questions

Q: What are the integrated diagnostic responses during an active communication link fault?

A: The module executes real-time self-diagnostic loops monitoring component integrity, signal validity, and network continuity. If a bus interruption occurs, the onboard processor flags the error register, logs technical fault variables, and outputs a hardware alert via the backplane to the host system.

Q: How does the hardware handle electrical noise within high-interference locations?

A: The board includes onboard filtering circuitry and low-pass electrical barriers across all physical inputs and communication lines. These components suppress high-frequency electromagnetic interference (EMI) and cross-talk, keeping signal data correct without requiring external inline filtering hardware.

Field Installation Guidelines

• Chassis Insertion: Disconnect all primary power from the rack before inserting the board. Align the module housing with the pre-allocated guide rails and press it evenly into the rear backplane slot until the latch mechanisms lock.
• Network Wiring Paths: Connect communication lines using shielded twisted-pair (STP) cables for RS485 ports and minimum Cat5e shielded cables for Ethernet connections. Route these low-voltage lines away from high-current AC motor supply wires.
• Grounding Requirements: Ensure the module faceplate is screwed securely to the metal rack frame. The chassis rail must maintain low-impedance grounding paths back to the central functional earth terminal to ensure correct surge protection operation.
