Product Description:

The 8AC140.60-2 belongs to the 8AC Powerlink Modules series manufactured by B & R Automation. This module is installed in distributed control cabinets to act as a communication and signal-conditioning node for industrial automation equipment. It bridges high-speed POWERLINK networking with local analog and digital inputs so that motion controllers or PLCs can sample field signals and drive actuators without requiring separate hardware tiers.

The local signal path uses an analog bandwidth of 10 kHz, and the internal filter passes fast transducer changes while suppressing higher-frequency noise. Sensors connect through an input stage whose impedance is 20 MΩ, and the high resistance minimizes loading errors on passive sources. Each converted value is delivered with 12-bit resolution, providing 4096 discrete steps across the ±10 V rated analog input range. A 32-kB SRAM cache buffers real-time variables, while 16 MB of DRAM stores protocol stacks and user code that run on a 100 MHz processor clock. System overhead is kept low, and the total power drawn from the backplane does not exceed 4.5 W, allowing dense panel mounting without oversized power supplies.

For fieldbus expansion, the CAN interface maintains reliable traffic over 1000 m of trunk line at rates up to 500 kbit/s, supporting remote drives or sensor clusters on large machines. PROFIBUS connectivity reaches 12 Mbit/s when higher deterministic throughput is required, and a diagnostic RS-232 port communicates at up to 115.2 kBaud for service access. Three digital I/O points share a combined output limit of 500 mA at the rated 24 VDC input level, and an event counter with 32-bit depth timestamps edge changes for sequence monitoring. Control logic persists in nonvolatile program memory, while buffered real-time variables remain available between bus cycles for synchronized motion and safety routines across the plant network.
