B&R Automation 7DI135.70 Digital Input Module

The 7DI135.70 Digital Input Module from B&R Automation is a compact, screw-in I/O option that provides four 24 VDC digital inputs in a sink configuration for fast, deterministic reading of binary signals in industrial automation systems. This 2003-era DI135 module is designed to support high-speed data inputs from sensors and encoders and is commonly used within B&R control configurations that require precise timing of input events, including encoder-related signaling and digital trigger conditions. Key performance figures include encoder operation up to 50 kHz and event-counter operation up to 100 kHz, along with a 24 VDC comparator output; the unit wires to a controller via a screw-in interface and is typically paired with the TB712 terminal block, ordered separately. The DI135.70 is a dedicated digital input module in B&R’s DI135 family and is intended for use in systems that need multiple fast, reliable 24 VDC inputs; its compact form factor and screw-in mounting simplify field installation while maintaining compatibility with B&R control systems.
