Product Overview
The B&R X67DM1321.L12 is a high-density digital mixed I/O module for
the IP67-rated B&R X67 distributed I/O system. It provides 16 digital channels that can
be individually configured by software as inputs or outputs.
Eight A-coded M12 I/O connections accommodate the 16 channels, allowing the module to
replace passive distribution arrangements while adding configurable I/O, diagnostics and
counter functions. The inputs use sink circuitry and the outputs use source circuitry.

assembly equipment, conveyor systems, material handling and modular production machinery.
Its M12 layout is suitable for concentrated groups of field sensors and actuators.
Maintenance and Replacement Notes
The suffix .L12 is part of the complete product model and must be retained.
This version has 16 channels and M12 I/O connections; it is not physically identical to the
standard eight-channel X67DM1321 with M8 connections.
Confirm the channel allocation, output loads, counter functions, M12 pin assignments,
X2X Link topology and Automation Studio hardware configuration before replacement.
