ABB CI590-CS31-HA 1SAP221100R0001 Communication Module

The ABB CI590-CS31-HA 1SAP221100R0001, also cataloged as the CI590-CS31-HA Communication Module, operates as a dedicated hardware component for CS31 slave communication and I/O signal processing within AC500 / S500 distributed automation networks.

Hardware Specifications

ABB Advant Bus & Deterministic Network Integration

• Backplane Bus Communication Velocity: Operates with deterministic CS31 bus cycles, supporting real-time data transfers across the S500 expansion bus without network latency.
• Profinet / EtherNet/IP & CS31 Compatibility: Configured as a media-redundant CS31 fieldbus slave, maintaining active signal synchronization across distributed PLC network topologies.
• I/O Density Scaling: Integrates 16 local configurable digital channels while allowing expansion up to 7 additional S500 I/O modules for scaled local control layouts.

Frequently Asked Questions

Q: Can the CI590-CS31-HA module be expanded with additional local I/O modules? A: Yes, the unit supports local expansion of up to 7 additional S500 I/O modules via its side-mount backplane bus interface.

Q: What power supply range is required for proper operation of the module? A: The module requires an input nominal supply voltage of 24 VDC within an allowable operating range of 20.4 to 28.8 V DC.

Q: What does media redundancy mean for the CS31 slave connection? A: Media redundancy enables the CI590-CS31-HA to maintain continuous communication across dual CS31 fieldbus lines if a physical cable break or line fault occurs on one channel.

Field Installation Guidelines

• DIN-Rail Mounting: Snap the module securely onto a standard 35 mm DIN rail inside an IP54 or higher industrial enclosure to ensure compliance with IP20 protection standards.
• Power & Field Wiring: Wire the 24 VDC power supply lines using copper conductors with appropriate wire ferrules. Ensure nominal input polarity is verified before energizing.
• Grounding & Shielding: Connect the CS31 bus cable shield to functional earth via low-impedance grounding clamps directly at the enclosure entry point.
• Bus Termination: Verify that correct bus line termination resistors are activated or connected at both physical ends of the CS31 fieldbus network segment.
