Product Description:

The X67BC4321.L12-10 is an input-output module from B & R Automation that belongs to the X67 Analog Input Output Modules series. Housed in an IP-rated enclosure, it is installed directly on the machine to shorten sensor and actuator wiring while communicating with the higher-level controller over a CANopen fieldbus backbone. Within an industrial cell, the device gathers process signals and switches peripheral loads, allowing distributed control without a centralized panel. This arrangement keeps field connections close to sensors, valves, and other devices mounted on the machine frame.

The module provides 16 digital channels that can be freely configured as inputs or outputs at the machine edge. All circuitry is supplied by a nominal 24 VDC bus, and galvanic separation up to 500 Veff maintains signal integrity between the internal logic, the field wiring, and the CANopen network. A molded housing qualified to IP67 blocks dust ingress and high-pressure water, so the unit can be mounted outside a cabinet. Bus data move at up to 1 Mbit/s, matching the maximum transfer rate permitted by CANopen for deterministic control traffic. Each output line sources up to 0.5 A, and the dedicated sensor and actuator supplies are rated at the same current.

The physical package measures 155 mm in height, 53 mm in width, and 42 mm in depth, with a mass of 300 g that does not over-stress light machine framing. A pluggable M12 backbone permits a segment length of 1000 m without repeaters, enabling large conveyor or assembly lines to share one CANopen domain. When connected to a B & R controller, the X2X link synchronizes local I/O every 500 µs and delivers up to 15 W of auxiliary power for status LEDs and internal logic. The aggregate load across all outputs is restricted to 8 A, providing headroom for solenoid valves, contactors, or small DC motors that reside on the same drop.
