In harsh industrial environments it supports redundant configurations for safety-critical applications and is used to monitor ON\/OFF signals from switches, relays, and sensors across oil \u0026amp; gas, LNG plants, chemical processing, and power generation facilities. Key specifications include module-level isolation (2 kV AC withstand), input current ~6 mA per channel with ON resistance ≤1 kΩ and OFF resistance ≥100 kΩ, contact rating 24 VDC (+20% \/ -10%), ≥10 mA, and an external 24 VDC power supply with ~200 mA capacity. The module accepts no-voltage (dry contact) signals and tolerates a maximum input voltage of 30 VDC, with a response time ≤40 ms. It weighs about 0.4–0.6 kg and operates from −20 to 70 °C. Common replacements include Yokogawa SDV144-S53 (newer revision), SDV144-S33 \/ S13 variants, and the Yokogawa SDV541 digital output counterpart.\u003c\/p\u003e\u003c\/div\u003e","brand":"Yokogawa","offers":[{"title":"New","offer_id":46241941881066,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-001.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/yokogawa-electric-corporation-sdv144-s63-digital-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
