B&R Industrial Automation X20DO6322 PLC Output Module

The X20DO6322 is a six‑output digital output module for B&R’s X20 I/O system that provides six 24 VDC current‑sourcing outputs, each able to switch up to 0.5 A with a combined nominal current rating of 3 A. It supports both 1‑ and 2‑wire connections and includes per‑channel diagnostics for monitoring output function and faults with a typical 10 ms delay. Electrical specs include a switching voltage of 24 VDC with a tolerance of -15%/+20%, an on‑resistance of 210 mΩ, a maximum peak short‑circuit current below 12 A, and an insulation voltage between channel and bus of 500 V_eff. The design includes an internal freewheeling diode for inductive loads, a leakage current of about 5 µA when the output is off, and protective features such as thermal shutdown in the event of overcurrent or short circuits. Power characteristics show bus power around 0.18 W and internal I/O consumption around 0.71 W, with an additional actuator‑related dissipation of about 0.31 W. For safety and compatibility, X20DO6322 carries certifications including CE, KC, and UL/cULus, along with hazardous‑location approvals (ATEX Zone 2 II 3G Ex nA nC IIA T5 Gc) and IP20 protection with an appropriate operating temperature range per X20 specifications. This module is designed for seamless integration into B&R X20 installations, enabling reliable, mapped 24 VDC output control across industrial automation tasks that require compact, standards‑driven I/O expansion.
