B&R Industrial Automation X20DO8322 Digital Output Module

The X20DO8322 is an eight‑channel digital output module for B&R’s X20 fieldbus I/O system, delivering eight 24 V DC current‑sourcing outputs with 1‑wire connections. Each output is rated for 0.5 A, giving a total nominal output current of 4 A, with a nominal switching voltage of 24 V DC and a regulation tolerance of -15% to +20%. The module provides protective and diagnostic features including thermal shutdown on overcurrent or short circuit, an internal freewheeling diode for inductive loads, RDS(on) about 210 mΩ, leakage current of 5 μA when off, and a peak short‑circuit current of less than 12 A; switching delays are under 300 μs for both directions, and overload shutdown switch‑on occurs in about 10 ms; output monitoring has a 10 ms delay. Power and consumption specs include bus power around 0.26 W and internal I/O power around 0.8 W, with the device designed for reliable, distributed control of relays, valves, and other 24 V loads in industrial automation, wired to the X20 bus and certified per applicable safety standards such as CE and UKCA.
