This module features 20 safe type A digital inputs and 4 pulse outputs, operating at a nominal 24 VDC. It is a critical component for safety-instrumented systems (SIS) in sectors such as automotive manufacturing, high-speed packaging, and robotic assembly lines, where immediate response to emergency stops, light curtains, or safety gates is mandatory.

The 20 safe digital inputs are classified as Type A, providing a robust interface for safety sensors. The inclusion of 4 pulse outputs allows for cross-fault detection and monitoring of the input wiring, ensuring that short circuits or cable breaks are identified in real-time. Power management is handled efficiently via the X20 bus with a low 0.4 W bus consumption, while the internal I\/O circuitry draws 1.6 W. The module supports \"Blackout Mode\" for the entire module scope, ensuring predictable behavior during signal interruptions. As a non-standalone module, it requires a safety controller (SafeLOGIC) to manage the safety protocol and logic execution across the network.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eX20SI9100\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBrand\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eB\u0026amp;R (Bernecker + Rainer)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModule Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSafe Digital Input Module\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eSafe Inputs\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e20 (Type A)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePulse Outputs\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e4\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eNominal Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e24 VDC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eVoltage Range\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e20.4 to 28.8 VDC\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMax.
