Product Description:

The B&R Automation range of I/O modules include the versatile X20DC1176 designed for connecting ABR incremental encoders. This module features an ABR incremental encoder interface that operates with symmetrical 5 V encoder inputs, enabling reliable signal processing for various applications. It features two digital inputs designed for 24 VDC nominal voltage. The inputs utilize sink configuration, connecting the load to the negative terminal. The module uses 3-wire connections for its digital inputs, allowing for straightforward wiring with power, ground, and signal lines. Each input boasts a resistance of 7.03 kΩ, which helps to ensure stable signal detection.

This module offers users options to customize features based on their particular application requirements. It supports both 16-bit and 32-bit counter sizes, allowing for customizable resolution. With a maximum input frequency of 600 kHz, the module can effectively handle high-speed signals in fast-moving processes. The module is also compatible with B&R's SafeLOGIC controller, enabling integration into safety-critical automation applications. The encoder offers a 4x evaluation rate, enabling detailed and accurate monitoring of movement.

The X20DC1176 operates reliably even in tough environments owing to its short-circuit and overload protection. It also provides a 500 Veff insulation voltage between the encoder and bus, enhancing the safety and integrity of data transmission. Installation of the module is straightforward with options for vertical or horizontal installation to suit different needs. The module is suited for -25 to 60°C operating temperatures and elevations of up to 2000 meters above sea level. The module has an IP20 degree of protection according to EN 60529 standards, which provides basic protection against contact and foreign objects. This B&R module is available from Wake Industrial with a one year warranty.
