Product Description

B&R Automation’s X20BB81 is a bus module designed to enhance system connectivity with one expansion slot for additional modules. It effectively facilitates the expansion of the I/O functionality in various applications by accommodating additional input or output modules. This unit features a pitch of 62.5 mm, which allows for standardization in the mounting and connection of multiple modules in a system. This helps to streamline integration and make installation simple. The module allows users to mount it based on their settings, allowing vertical or horizontal orientation for installation. Its versatility provides adaptability to various system configurations and application needs.

The X20BB81 has a nominal voltage of 24 VDC for its I/O power supply. It is designed to handle a permissible contact load of up to 10 A, allowing users to connect various components. The module has a 0.50 W typical power consumption from the bus, keeping energy demands on the overall system low. The module can withstand contact with larger objects above 12 mm, but its IP 20 ingress protection level does not safeguard against dust or moisture. Users should take extra precautions in such conditions to ensure the longevity and reliability of the module.

This module operates optimally in standard industrial conditions and can withstand operating temperatures of -25 to 60°C. However, vertical installations can only accommodate temperatures up to 50°C so users should consider their ambient conditions when selecting an appropriate installation method. The safety and quality of the unit is certified by CE, UKCA, ATEX, UL, and other relevant industry bodies. This indicates that the module performs in line with stringent standards for performance and safety in industrial automation applications.
