Product Description
The B&R 7DO135.70 is a compact high-reliability FET digital output module developed for B&R X20 distributed automation control systems. Serving as the core switch signal output and field actuator driving unit in industrial PLC control platforms, it undertakes digital switch signal conversion, on-site equipment on/off logic control, auxiliary linkage driving and real-time signal transmission tasks. It converts internal system logic commands into stable DC switch output signals, accurately driving industrial relays, solenoid valves, indicator lights and low-power auxiliary equipment, providing reliable discrete control support for mechanical manufacturing, process automation and intelligent production systems.

Adopting industrial-grade FET switching circuit architecture and high-stability logic processing algorithm, this module is equipped with 4 independent digital output channels, supporting 12–24 VDC industrial voltage range and 0.1 A single-channel rated load current, adapting to most low-power field switch control scenarios. It features fast response switching performance and excellent long-term operational stability, ensuring precise and consistent execution of frequent logic linkage actions. This module requires a separate TB712 terminal block for standardized field wiring, achieving neat wiring layout and stable signal access. Fully compatible with B&R dedicated bus architecture, it supports low-latency real-time command synchronization and remote parameter configuration. Built-in overcurrent protection, short-circuit suppression and circuit anti-interference mechanisms effectively avoid equipment damage and signal jitter caused by on-site load abnormalities. With compact screw-in modular structure, industrial EMC compatibility and wide-temperature anti-aging design, it supports 24/7 uninterrupted stable logic control for mission-critical industrial automation systems.
