Product Description:

The X67DO1332 digital output module is produced by B&R Automation as part of the X67 I/O Modules series. This compact unit extends a machine’s remote I/O station with eight high-side switching channels and is intended to actuate solenoids, contactors, or indicator lamps directly from field wiring. By converting the controller’s logic signals into power-rated outputs at the installation point, it reduces cabinet wiring and helps maintain deterministic response in distributed automation architectures.

Its outputs are designed for a nominal field supply of 24 VDC, and the module provides 8 sourcing channels that each deliver up to 2 A of continuous load current through a current-sourcing FET stage. A switch-on delay of <250 µs ensures fast reaction to control commands, while off-state leakage remains limited to 5 µA so sensitive loads stay de-energized. Under load, the residual voltage stays below <0.5 V at 2 A, which helps minimize power dissipation across the device. The channel electronics tolerate resistive switching up to 100 Hz, and the combined load draw across the connector is limited to 8 A to protect upstream wiring. Internal I/O electronics consume 2 W, and the X2X link that carries both power and communication adds another 0.75 W, leaving most of the supply available for connected actuators.

Actuator power that can be sourced through the module is capped at 12 W, which helps keep thermal loading manageable inside sealed installations. When de-energizing inductive devices, the integrated clamp limits the back-EMF to 50 VDC, protecting upstream cables and supplies. If a short circuit occurs, the output stage withstands a surge of <21 A before electronic shutdown. Switch-off latency remains below 270 µs, matching the fast turn-on characteristic for symmetrical timing. The overmolded housing carries an IP67 rating, permitting direct mounting on moving axes or in washdown zones without auxiliary enclosures.
