Why Choose the ABB CI522-MODTCP Modbus TCP Communication Interface Module?
The ABB CI522-MODTCP, part number 1SAP222200R0001, is a Modbus TCP communication interface module designed for decentralised I/O applications in ABB AC500 and S500 automation systems. It combines 8 digital inputs, 8 digital outputs and 8 configurable digital inputs/outputs in one compact module, providing a flexible interface for industrial automation networks.
The CI522-MODTCP operates as a Modbus TCP server and provides 24 V DC digital inputs together with transistor outputs rated up to 0.5 A. The eight configurable channels can be software-configured as digital inputs or outputs, allowing the available I/O to be adapted to the requirements of the connected machine or process.
The module provides two Ethernet connections through its compatible terminal unit, supporting flexible Modbus TCP network layouts and daisy chaining. It also supports expansion with up to 10 S500 I/O modules, while module-wise galvanic isolation separates the I/O section from the Ethernet network for reliable industrial communication.

Reliable Modbus TCP Communication for Industrial Automation
The ABB CI522-MODTCP provides a compact decentralised I/O solution for Modbus TCP industrial networks. Its combination of fixed and configurable digital channels allows a controller to monitor sensors and switches while controlling actuators, valves, contactors and other digital field devices from a distributed I/O location.
The eight configurable digital channels provide additional flexibility because each channel can be assigned as an input or output through software configuration. Combined with expansion capability for up to 10 S500 I/O modules and two Ethernet connections, the CI522-MODTCP is suitable for distributed machine and process automation architectures.
