Product Description:

The 7XV108.50-51 is a remote valve terminal module produced by B&R Automation within the 7XV Remote Valve Terminals series. It serves as a field-mounted output block that drives pneumatic solenoids from a 24 V DC control system and exchanges status data with higher-level controllers over the X2X real-time network. By locating electrical switching circuitry near actuators, the unit reduces wiring runs, simplifies cabinet layouts, and supports decentralized machine architectures common in modern industrial automation.

The device provides 8 sourcing digital outputs for valve coils, each referenced to a common 0 V. A system supply of 24 VDC energizes the electronics, and every channel can deliver up to 0.1 A while staying within thermal limits. Output transistors can toggle loads at a maximum of 100 Hz, making the block suitable for fast-acting pneumatic functions such as blow-off or pick-and-place grippers. Typical turn-on propagation is only 100 µs, so command latency remains minimal when the module is installed at the end of an X2X segment. The output stage follows a sourcing topology, meaning positive voltage is switched to the load, which matches the wiring conventions of most 24 V solenoids and relays on automated machinery.

A die-cast housing with an IP67 rating protects the electronics against dust and washdown fluids. Overall dimensions are 62 x 70 x 30 mm, and the assembly weighs only 125 g, which helps minimize stress on mounting brackets. The fieldbus is brought in through a shielded M12 connector, while an M8 plug supplies auxiliary power and a 25-pin DSUB mates with the pneumatic manifold. Internal logic consumption remains at 1.5 W and the X2X backplane draws 0.75 W, keeping the total load on the 24 V supply below the 0.8 A unit rating even during simultaneous switching events.
