Designed for safety-critical machine automation, it provides 16 current-sinking safety input channels capable of evaluating single- or dual-channel safety devices. The unit communicates using the CIP Safety protocol over EtherNet\/IP, seamlessly interfacing with GuardLogix, GuardPLC, or SmartGuard controllers to meet SIL 3 and Category 4 \/ PLe requirements.\u003c\/p\u003e\n\u003ch3\u003eSafety Input Configuration and Diagnostic Pulse Testing\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1791ES-IB16\u003c\/strong\u003e can be configured for 16 single-channel safety inputs or 8 dual-channel safety inputs depending on system safety architecture. It incorporates built-in test pulse outputs that continuously monitor field wiring for short circuits, cross-faults, and ground faults without interrupting operational signals. Point-level channel diagnostics provide immediate feedback regarding open loops, line faults, or channel discrepancies.\u003c\/p\u003e\n\u003ch3\u003eNetwork Integration and Cabinet Installation\u003c\/h3\u003e\n\u003cp\u003eIntegrating CIP Safety over standard EtherNet\/IP enables safety signals and standard control data to traverse the same network cable. Network configuration and safety signature management are managed through Studio 5000 Logix Designer via assigned Safety Network Numbers (SNN). The module features an integrated DIN rail mount, removable terminal blocks for simple field replacement, and front-panel status LEDs indicating module health, communication status, and individual input channel states.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1791ES-IB16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eCompactBlock Guard I\/O Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eCIP Safety Guard I\/O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety Level\u003c\/td\u003e\n\u003ctd\u003eSIL 3 (IEC 61508), PLe (ISO 13849-1), Cat 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n\u003ctd\u003e16 single-channel or 8 dual-channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Type\u003c\/td\u003e\n\u003ctd\u003e24 VDC current sinking\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Pulse Outputs\u003c\/td\u003e\n\u003ctd\u003e8 or 16 standard pulse outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Operating Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (11 to 28.8 VDC range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocol\u003c\/td\u003e\n\u003ctd\u003eEtherNet\/IP (CIP Safety)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003e35 mm DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.90 lbs (0.41 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1791ES-IB16 inputs be configured for both single-channel and dual-channel safety devices?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module supports configuration as either 16 independent single-channel safety inputs or 8 dual-channel safety input pairs via programming software.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the pulse test outputs on the 1791ES-IB16?\u003c\/p\u003e\n\u003cp\u003eA: Pulse test outputs supply power to field contact devices (such as E-stops or interlocks) while injecting microscopic low pulses to detect wire-to-wire shorts and short-circuits to 24 VDC power.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":67049783656563,"sku":"1791ES-IB16","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1791ES-IB8XOBV4_Cocoai.jpg?v=1793259187","url":"https:\/\/www.dcssupplier.com\/products\/allen-bradley-1791es-ib16-i-o-module","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
