The ABB CD522 Function Module is a multi‑function encoder and digital I/O interface module designed for use with the ABB AC500 PLC and S500 I/O system. It combines high‑speed encoder/counter functions, PWM/pulse outputs, and flexible digital input/output capabilities in a single module, allowing it to handle motion feedback, fast counting, and general digital I/O in industrial control and applications. The CD522  module supports incremented counting up to high frequencies and integrates easily with AC500 controllers via the system I/O bus.

Frequently asked questions：

Q1: How many encoder channels does the CD522 support?

A: It supports 2 encoder inputs for motion feedback and counting.

Q2: How many digital input / output channels are available?

A: The module provides 2 fixed digital inputs and 8 configurable digital input/output channels (24 V DC).

Q3: What kind of outputs can the CD522 provide?

A: It includes 2 PWM/pulse outputs plus the configurable DI/DO channels.

Q4: What PLC system is the CD522 compatible with?

A: It integrates with the ABB AC500 and S500 I/O system via the I/O bus.
