Product Description:
The X67BC7321-1 is an I/O expansion node produced by B&R Automation and belongs to the X67 Analog Input Output Modules series. Intended for distributed machine and plant control, the unit links field sensors and actuators to a central controller over a single cable. This reduces panel wiring and permits modular expansion directly on the machine frame. Its decentralized design lets signal collection occur closer to connected devices, which can shorten cable runs and reduce the amount of terminal hardware needed in the control cabinet.
The module communicates over a 1 CAN I/O bus interface, and the extended CAN profile allows additional diagnostic telegrams beyond standard cyclic data. Parameterization is handled through an automatic configuration routine, eliminating manual address switches. All electrical terminations use the compact M8 connector, which simplifies daisy-chain cabling in tight spaces. The module provides 8 digital I/O points, and each channel can be programmed individually as an input or a low-side switch output. It also includes 2 on-board event counters that capture rising or falling edges for speed or quantity monitoring, and each counter supports a maximum rate of 50 kHz for direct measurement of high-frequency pulse trains. An adjustable input filter suppresses contact bounce, and function model 254 identifies the feature set within the X2X network stack.
The electronics draw 10.30 W from the segment supply, which contributes to overall heat dissipation. Field devices powered through the block must stay within a permissible I/O current of 4 A to avoid trace overload. Each switched output channel is limited to 0.5 A, allowing accurate sizing of fusing and wire gauges. Logic circuits operate from a nominal bus voltage of 24 VDC, aligning with standard machine power rails. That arrangement supports common 24 V control architectures and keeps the module compatible with typical industrial power distribution. The X2X link itself contributes 3 W to the overall power budget, and a maximum segment length of 100 m supports installation across large machines without repeaters.
