B&R Industrial Automation X20DM9324 IO Module

The B&R X20DM9324 is a digital I/O module in the X20 system that provides 8 digital inputs and 4 digital outputs, both 24 VDC, designed for 1-wire connections with X20 terminal blocks, and it carries module revision E0. It operates from a 24 VDC supply with an input tolerance of -15%/+20% and interfaces to the X20 backplane bus to support rapid, compact discrete I/O switching in automation panels. Typical power dissipation includes a 0.21 W bus draw, 0.5 W for internal I/O, and 1.17 W for external I/O, with up to about 0.21 W additional when actuators introduce load; diagnostic visibility is provided via a run/error LED indicator and software-mapped status. The module carries CE, KC, UL/cULus E115267, ATEX Zone 2 II 3G Ex nA nC IIA T5 Gc IP20, cCSAus, and EAC approvals, and is rated IP20 for indoor industrial environments. Its B&R I/O data code is 0x20B9, and it exposes eight input channels and four output channels for digital-signal interfacing, making it suitable for sensing applications (proximity switches, limit switches) and discrete actuator control within an X20-based control cabinet. Designed for use with the X20 terminal block ecosystem, the DM9324 integrates into machine and panel controls that require robust 24 VDC I/O with reliable diagnostic feedback.
