Why Choose the ABB AC522 Analog Input/Output Module?
The ABB AC522, order code 1SAP250500R0001, is an S500 analogue input/output module with 8 configurable analogue channels. Four channels can be configured as analogue inputs for voltage, current, RTD or digital signals, or as analogue voltage/current outputs, while the remaining four channels can be configured as analogue inputs or voltage outputs.
The AC522 supports a flexible combination of process measurement and control signals, including voltage, current and RTD inputs alongside voltage and current analogue outputs. This makes the module suitable for mixed automation applications where both field measurement and analogue actuator control are required.
With 13-bit analogue input and output resolution, module-level galvanic isolation and individual yellow channel-status LEDs, the AC522 provides compact signal conditioning and monitoring within compatible ABB AC500 S500 architectures. It uses a 1-wire module interface and is installed with a compatible TU515 screw-terminal or TU516 spring-terminal unit.
Key Advantages
- 8 configurable analogue I/Os: Provides flexible signal acquisition and analogue control in one compact S500 module.
- Mixed input/output functionality: Four channels support AI U/I/RTD/DI or AO U/I, while four additional channels support AI U/I/RTD or AO U.
- Wide signal compatibility: Supports common industrial voltage, current and RTD signal types.
- 13-bit resolution: Provides detailed analogue conversion for compatible AC500 control applications.

Flexible Analogue Measurement and Control for ABB S500
The ABB AC522 is designed for applications requiring configurable analogue measurement and output control within an AC500 automation system. Its first four channels can be individually assigned to analogue input, digital input or analogue output functions, while the remaining four channels can operate as analogue inputs or voltage outputs. This arrangement allows the module to accommodate mixed field requirements without dedicating separate modules to every signal type.
Analogue inputs support voltage, current and RTD signal types, while compatible analogue outputs provide voltage or current control depending on the selected channel. The module's 13-bit resolution, galvanic isolation and local LED indication support practical commissioning, monitoring and control of industrial process signals. The AC522 is installed using an appropriate ABB S500 terminal unit and can form part of central or decentralised AC500 I/O architectures.
