The ABB 3BHE022293R0101 (PC D232A / PEC80-CIO Communications & I/O Module) is a module in ABB’s DCS / PEC control system family that combines communication interfaces and input/output (I/O) expansion functions. It is typically installed in control racks and bridges the control system to field devices by providing digital / analog I/O and communication ports.

Unified communication + I/O module
Reduces the need for separate interface and I/O boards, simplifying system design and wiring.
High flexibility & configurability
Mixed types of channels allow adaptation to various system requirements (analog, digital, temperature).
Redundant design for reliability
Supports communication and power redundancy, improving fault tolerance.
Industrial-grade resilience
Wide temperature range, isolation, and environmental tolerance make it suitable for harsh control environments.
Protocol compatibility
Supports multiple communication protocols, easing integration with diverse devices.
Modular and maintainable
Insertable/replaceable module design enables easier maintenance, upgrades, and fault replacement.
DCS / PEC systems as communication and I/O expansion modules
Power plant excitation or control systems (some sources list it as “Excitation Control Module”)
Process automation / control systems in chemical, petrochemical, power, metallurgy, water treatment
SCADA / remote monitoring systems connecting to sensors / actuators
Control cabinets or rack-mounted systems for I/O convergence and communication hubs
Check exact submodel / revision
Different firmware versions or hardware variants may have different I/O channel counts or port features. Verify module labeling or documentation.
Use redundant power feeds in critical systems
Connect dual 24 V inputs to ensure uninterrupted operation under single power source failure.
Proper cabling & line routing
Use shielded twisted-pair communication cables, avoid routing alongside high-power lines, adhere to recommended cable impedance and length limits.
Grounding & isolation
Ensure proper grounding of signal and power grounds; avoid ground loops.
Thermal and ventilation considerations
Under full load, the module may generate heat; ensure cabinet airflow, avoid stacking modules too tightly.
Periodic inspection & diagnostics
Regularly monitor I/O statuses, voltage levels, communication health, and check connectors / terminals for integrity.
Spare module planning
Maintain a spare unit to allow quick replacement in case of failure, reducing system downtime.
