Product Description:

B&R Automation’s X67DI1371.L12 BR belongs to the X67 Analog Input Output Modules series and functions as a remote digital input block for machine-level I/O collection. Mounted directly on tooling or conveyor frames, the module gathers on/off signals from sensors and pushbuttons and forwards them to the higher-level controller through the series bus coupler. Its compact, sealed housing allows installation outside the control cabinet so proximity wiring stays short and field devices can be powered locally. This layout helps reduce long sensor runs and keeps I/O closer to the devices being monitored.

The unit offers M12 connectors arranged for quick-disconnect sensor cabling, and it provides 16 digital input channels that share a common 24 V sensor supply. Each input uses a sink circuit topology, meaning the sensor switches the line to ground and the module detects the voltage drop. Signal debouncing is handled in hardware by a 1 ms input filter, which helps prevent chatter from mechanical contacts before data reaches the PLC. Field wiring and logic levels remain electrically separate from the internal electronics through galvanically isolated I/O groups, helping protect the controller from ground loops. The inputs accept a nominal level of 24 VDC, which matches standard machine power rails and avoids external converters.

The module has an IP67 protection rating, which blocks dust ingress and withstands temporary water immersion. Despite its compact footprint, it meets the series’ high-density classification by packing a full set of channels into a single device. The plastic enclosure is fully sealed, so no additional gasketing is required when it is bolted to metal structures or cable trays. Individual channel status is reported through onboard LEDs, allowing quick visual checks of sensor operation and wiring continuity without external test equipment.
