Why Choose the ABB AX522 Analog I/O Module?

The ABB AX522, order code 1SAP250000R0001, is an S500 analogue input/output module providing 8 analogue inputs and 8 analogue outputs for compatible ABB AC500 automation systems. The module supports voltage, current and RTD signal types on its analogue inputs, while all eight analogue outputs provide voltage output capability and the first four can additionally be configured for current output.

Each analogue input can be individually configured for common industrial signals including 0–10 V, ±10 V, 0–20 mA, 4–20 mA, Pt100, Pt1000 and Ni1000. The inputs can also be used for 24 V DC digital input signals in suitable configurations, providing additional flexibility for mixed process and machine-control applications.

The AX522 uses 13-bit analogue conversion resolution according to current ABB product data and operates from a 24 V DC process supply. Its compact S500 format, module-wise galvanic isolation and compatibility with TU515 screw-terminal and TU516 spring-terminal units make it suitable for central and distributed AC500 I/O architectures.

Key Advantages

• 16-channel analogue I/O: Combines 8 analogue inputs and 8 analogue outputs in one compact S500 module.
• Flexible input configuration: Supports voltage, current and RTD measurement signals across the eight analogue inputs.
