It captures discrete signals from field devices such as pressure switches, limit switches, and push buttons, converting physical contact states into digital signals for the system processor. This module ensures reliable signal acquisition and system integrity in demanding industrial environments. We supply this unit as 100% brand new, original hardware manufactured in France.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eARM15A (SARM15A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Type\u003c\/td\u003e\n\u003ctd\u003eMechanical relay contact input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e7.6 cm × 17.8 cm (3.0\" × 7.0\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e 0.3 kg \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Indication\u003c\/td\u003e\n\u003ctd\u003eLED indicators per input channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eStandard I\/O module nest compatible\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003e100% Brand New Original\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eSuperior Noise Immunity\u003c\/strong\u003e\u003cbr\u003eMechanical relay-based input design provides strong galvanic isolation, effectively protecting the control system from electromagnetic interference (EMI) and electrical noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUltra-Lightweight Design\u003c\/strong\u003e\u003cbr\u003eWith a weight of only 0.1 kg, the module reduces mechanical load on the I\/O backplane and simplifies handling during installation or replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDirect Field Interfacing\u003c\/strong\u003e\u003cbr\u003eSupports direct connection of dry contact inputs, eliminating the need for additional signal conditioning or interposing relays, thereby reducing wiring complexity.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptimized Space Utilization\u003c\/strong\u003e\u003cbr\u003eThe compact 7.6 cm width enables high-density I\/O configurations, allowing more channels to be installed within limited cabinet space.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between ARM15A and SARM15A?\u003c\/strong\u003e\u003cbr\u003eThe “S” prefix typically indicates a revision or internal classification.
