Product Description:
The X67BC81RT.L12 module is produced by B&R Automation and belongs to the X67 Analog Input Output Modules series. It is a compact, field-mounted unit that collects mixed-signal data, drives actuators directly on the machine, and transfers information to higher-level controllers through real-time POWERLINK networking. By combining analog bipolar voltage channels with low-voltage digital points in a sealed housing, the device simplifies installation in distributed control architectures used in packaging lines, assembly cells, and process skids.
The module provides two sinking or sourcing 24 V inputs and two bidirectional points at the same voltage, for a total of four high-level digital channels. The entire 24 V section may draw up to 0.4 A, which should be considered when sizing the sensor supply and its protective fuses. A separate set of three 5 V digital I/O points supports TTL-level devices without requiring the high-level channels. On the analog side, the module provides two differential inputs, with each sample converted in 5 µs and digitized at a 13-bit resolution across a full-scale range of ±10 V. A continuous throughput of 200 kHz allows the inputs to monitor rapidly changing signals from compatible transducers, including vibration probes and other high-speed sensors.
Output capability is provided by one analog output that updates in 2.5 µs and delivers a new voltage value during each cycle. The output uses the same bipolar range and conversion resolution as the analog input section, allowing consistent scaling of acquired and generated signals. Field wiring for power and signal connections terminates on keyed M12 connectors, which provide secure connections in machine-mounted installations. Communication is routed through two POWERLINK ports, allowing the block to pass real-time network traffic between connected devices. Power available to the internal electronics is limited by a 15 W X2X Link budget, so the combined load must remain within that limit when multiple modules are connected in a daisy chain.
