X20SI8110

The X20SI8110 module from B & R Automation belongs to the X20 Fieldbus Input Output Modules series, offering a compact yet powerful interface solution for industrial automation. This module features 8 Digital Sink Inputs operating at a nominal voltage of 24 VDC with a voltage range of 24 VDC -15% / +20%, ensuring compatibility with a wide array of control systems. With a slim width of 12.5 mm and overall Dimensions (hxdxw) of 99 x 73 x 12.5 mm, it minimizes panel space usage while delivering robust performance. Part number X20SI8110 carries the quality stamp of B & R Automation and integrates seamlessly into modular X20 architectures, fulfilling critical signal acquisition roles in machine automation. The module’s Insulation voltage between channel and bus of 500 V guarantees safe electrical separation in harsh industrial environments.

Designed for precision and reliability, the X20SI8110 leverages an Input circuit type of Sink with an Input resistance of minimum 7.33 kΩ to ensure accurate signal detection. Integrated reverse polarity protection shields the electronics from wiring errors, while the leakage current when switched off of just 0.1 mA minimizes power loss and prevents false triggering. Each of the eight channels includes dedicated LED status indicators for I/O function, operating state, and module status, enabling immediate visual feedback during commissioning and maintenance. Rapid fault isolation is supported by an Error detection time of 100 ms, allowing control systems to respond swiftly to abnormal conditions. These technical capabilities combine to deliver dependable performance under variable load and environmental stresses.

In daily operation, the X20SI8110 enhances system uptime through comprehensive diagnostics and user-friendly feedback. Its multiple Status indicators display real-time I/O channel states and module health, reducing troubleshooting time and resource requirements. The module supports both Horizontal and Vertical mounting orientations, giving engineers flexibility when designing machine layouts or retrofitting existing panels. The slim footprint and front-panel LED interface streamline wiring and configuration tasks, while the low leakage current and high insulation voltage provide electrical safety and signal integrity. With reliable module run/error signaling through both hardware and software channels, engineers can implement predictive maintenance strategies to avoid unplanned downtime.

Integration of the X20SI8110 into distributed I/O networks is straightforward, thanks to its native compatibility with the X20 bus system and compact form factor. The module’s robust design and industry-standard connectivity allow it to serve in applications ranging from packaging machines to process control systems. By consolidating eight digital sink inputs into a single 12.5 mm-wide housing, this unit optimizes panel density and simplifies wiring harnesses. The X20SI8110’s seamless fit within B & R Automation’s modular X20 ecosystem makes it an ideal choice for scalable machine automation and factory integration projects.
