Product Description:

The X67DI1372 is an eight-channel digital input module produced by B & R Automation as part of the X67 Analog Input Output Modules series. Designed for on-machine mounting, it converts discrete field contact states into serial data for the controller, letting distributed architectures replace centralized terminal strips. Its role is to report switch, sensor, and interlock conditions to the control system with very little delay so machine responses stay coordinated at the point of use. Using 24 V logic common to sensors and actuators, the unit streamlines wiring in transfer lines, assembly stations, and robotic cells.

Field terminations are handled by M12 threaded connectors fitted with B-coded inserts, so power pins remain segregated from signal conductors and accidental cross-mating is prevented. The device accepts 8 input channels that share a common reference, yet they remain electronically isolated to help keep a fault on one sensor from affecting the others. Each input is processed through a 1 ms digital filter that suppresses chatter and noise before the state is latched. The circuitry follows source wiring conventions, meaning the sensor supplies current to the module input. Stable operation is supported when the supply is 24 VDC, which matches the nominal voltage used by most industrial proximity switches and optically isolated contacts.

Communication with upstream automation nodes is achieved through the X2X Link serial backplane. This channel enters the housing through a dedicated one input port and passes downstream through a one output port, allowing daisy-chain expansion without external hubs. Because the network continues through the module, additional stations can be placed close to field devices instead of routing every signal back to a central enclosure. The link refreshes data deterministically so combined modules can meet the cycle times required by coordinated machine functions. Diagnostic LEDs beside each channel provide immediate visual status, and the encapsulated electronics tolerate the vibration and moisture commonly present on plant-floor equipment.
