B&R Industrial Automation DM435 Input Output Module

The B&R 7DM435.7 is a digital mixed I/O module in the 2003 I/O family that provides eight 24 VDC inputs and eight transistor outputs, delivering a 1 ms response time for fast digital control tasks. It supports both sink and source wiring on its inputs and offers eight 24 VDC transistor outputs rated for 0.5 A each. The module requires a supply voltage above 18 V and draws up to 0.5 W of power; LED indicators show supply status and output activity. Input voltage ranges from 18 VDC to 30 VDC (nominal 24 VDC) with switching thresholds of <5 V for LOW and >15 V for HIGH. The DM435 is C-UL-US listed, carries the B&R ID Code $E3, and is identified as a B&R 2003 I/O Module; terminal blocks are not included in the delivery and must be ordered separately (e.g., 7TB-series blocks). Designed for mounting on B&R’s 2003 I/O bus, it can be paired with CP/EX adapters (such as CP430/EX270 or CP470/CP770 and other CP/EX variants) to connect to fieldbus networks, making it suitable for compact control tasks that require both digital inputs and outputs in a single, space-efficient slot.
