B&R Industrial Automation X20AO4622 Analog Output Module

The B&R X20AO4622 is a four-channel analog output module for the X20 I/O family, delivering high-resolution control signals from the X20 fieldbus to external actuators with a 13-bit DAC per channel. Each channel can be configured as a voltage output up to ±10 V or as a current output in the 0–20 mA or 4–20 mA range, enabling both voltage-driven actuators and current-loop devices from a single module. It is designed for use with X20 terminal blocks (12-pin) and integrates with B&R's Powerlink/X2X-style fieldbus connections, offering independent channel operation and output protection such as short-circuit protection. Typical uses include precise valve control, analog setpoints for automation processes, and calibration tasks in CNC and manufacturing environments where four discrete, programmable analog outputs streamline wiring and cabinet footprint. With four outputs and protective features that help ensure reliable operation in harsh industrial environments, the X20AO4622 maintains stable analog signaling in demanding automation tasks.
