Core Information of X20AO2622
X20AO2622 is a 2-channel analog output module from B&R’s X20 product series, designed for
industrial automation systems. It supports both voltage (±10 V) and current (0–20 mA / 4–20 mA)
output signals, featuring 13-bit converter resolution, short-circuit protection, and compliance with
multiple industrial certifications, making it suitable for process control, actuator driving, and other
precision analog signal output scenarios.
●Model Number: X20AO2622
●Product Series: B&R X20 I/O System
●Core Function: Provides 2 independent analog output channels, configurable for voltage or current
signals via terminal selection, enabling precise control of industrial actuators and instruments.
