Product Description:

The 7XV108.50-62 is an electronic valve output module produced by B&R Automation for use within the 7XV Remote Valve Terminals series. The unit interfaces with decentralized pneumatic or hydraulic manifolds and supplies controlled power to individual solenoid coils, allowing machine controllers to actuate process valves without local relay wiring. By placing the driver close to field devices, the module simplifies installation and reduces response times in industrial automation lines.

The housing measures 67 × 66 × 30 mm, so the module fits into compact tool heads and conveyor frames while leaving room for cabling and air lines. Its enclosure is sealed to IP67, permitting direct mounting in washdown or dust-laden areas without a cabinet. Each output channel can source up to 0.1 A and switch loads at frequencies up to 100 Hz; this combination supports on-off and simple proportional valve coils. The typical turn-on latency is 100 µs, which maintains timing accuracy during fast indexing cycles. Internally, the circuitry uses a high-side sourcing configuration, so load commons remain at field ground and open-load diagnostics are straightforward. Short-circuit, overload, and overtemperature protection is integrated into every channel to prevent wiring faults from propagating upstream.

The control electronics draw a maximum of 1.5 W from the local I/O rail when no valves are energized, while the output stages are limited to a combined 0.8 A to keep temperature rise predictable. The board provides 8 valve outputs, with pin 13 and pins 22 through 25 reserved as dedicated grounds to provide clean return paths for coil currents. Power enters through an M8 connector, network communication uses an M12 bus port, and up to 0.75 W can be drawn from the X2X link for internal logic. Despite its protective metal shell and conformal-coated electronics, the assembly weighs only 131 g, reducing the additional load placed on moving axes and compact machine assemblies.
