Product Description:
The 8AC131.60-1 module from B&R Automation belongs to the 8AC Powerlink Modules series and serves as an analog and counter interface for industrial controllers. It captures low-level process signals, digitizes them, and publishes the data over the real-time POWERLINK bus so a PLC can monitor or adjust machine behavior without added processing delay. With its compact form factor, the device is typically mounted close to sensors or encoders, reducing wiring length and improving immunity to electrical noise.
Each of the two analog channels features a 12-bit successive-approximation ADC that completes a conversion in less than 50 µs, allowing the controller to track rapidly changing inputs without aliasing. At 25 °C, the module sustains a measurement accuracy of ±0.05%, while nonlinearity remains within ±1 LSB for consistent scaling across the entire range. A first-order filter with a cutoff of 10 kHz attenuates high-frequency interference before sampling, and signal validity is checked against a low threshold below 5 V and a high threshold above 15 V. Temperature effects are minimized by a gain drift no greater than ±0.006 %/°C and an offset drift limited to ±0.0005 %/°C. Two differential inputs are provided, so the module presents 2 independent measurement paths, each with an input impedance above 10 MΩ. A 16-bit counter resource is also available to accumulate edge events when a dedicated encoder line is connected.
The digital section draws its logic from a 24 VDC supply and never exceeds a thermal budget of 1 W, making heat dissipation straightforward inside densely packed cabinets. Field devices can drive the counter input at rates up to 100 kHz, and accumulated values are stored in a 16-bit register before being forwarded over the network. The output stage can source up to 45 mA for transistorized status LEDs or test points, and the low power draw helps the module operate in tightly packed control enclosures.
