Dual-line 24 VDC supply supports independent powering of 16-point groups, reducing risk of cross-channel interference. Dry contact detection thresholds (≤150 Ω ON, ≥200 kΩ OFF) ensure deterministic input state recognition.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the SARM15A-000 detect low-level leakage currents? A: Yes, OFF-state detection requires ≥200 kΩ resistance, preventing false triggering from leakage paths.\u003c\/p\u003e\n\u003cp\u003eQ: How is redundancy achieved in field power supply? A: Dual-line 24 VDC supply allows independent powering of two 16-point groups, supporting redundancy and load distribution.\u003c\/p\u003e\n\u003cp\u003eQ: What is the recommended installation form factor? A: The module is designed for 19-inch rack mounting, occupying 3U height with M4 screw terminals for field wiring.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the module securely in a 19-inch rack using designated hardware.\u003c\/li\u003e\n\u003cli\u003eEnsure M4 screw terminals are tightened to specified torque to prevent conductor loosening.\u003c\/li\u003e\n\u003cli\u003eSegregate dry contact wiring from analog loops and high-voltage lines to reduce interference.\u003c\/li\u003e\n\u003cli\u003eMaintain clearance for airflow and inspection during maintenance.\u003c\/li\u003e\n\u003cli\u003eVerify insulation resistance before energizing to ensure ≥10 MΩ compliance.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":44105211347018,"sku":"SARM15A-000","price":220.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8569\/3770\/files\/ARM55D.png?v=1744094986","url":"https:\/\/www.topbrandsplc.com\/products\/yokogawa-sarm15a-000-relay-contact-input-module","provider":"Topbrands PLC Limited","version":"1.0","type":"link"}
