B&R Industrial Automation X67DM1321 Digital Module

X67DM1321 is an eight‑channel digital mixed I/O module for the B&R X67 system, offering configurable channels that can operate as inputs or outputs via software, with 24 V DC nominal supply and a total I/O power budget of 0.5 A. The module supports sink inputs and source outputs, provides short-circuit protection on outputs, and delivers single‑channel diagnostics for each channel, plus two additional channels with counter functions for simple event counting. Connectivity includes 8x M8 3‑pin I/O connectors and an M8 4‑pin supply, plus an X2X Link interface via M12 B‑coded connectors; the X2X Link consumes about 0.75 W, while the module’s internal I/O consumption is around 2.5 W. Electrical isolation between each channel and the bus is 500 Veff, and the device is IP67 rated with an operating ambient temperature range from 0 to 60°C. The X67DM1321 carries certifications including CE, UKCA, ATEX Zone 2 (II 3G Ex nA IIA T5), TÜV ATEX, UL cULus, KC, and cCSAus, reflecting suitability for hazardous locations and general industrial environments. The B&R ID code for this module is 0x1311, and the product description notes eight digital channels with the ability to configure them as inputs or outputs, along with two additional counter-enabled channels.
