Each channel accepts 12–24 V field signals, enabling direct connection to common sensors and switches. The module is powered from a 120 VAC supply (up to 500 mA) and uses a 5 VDC supply for its internal logic. Dimensions are 1.5 in W × 6.5 in L × 1.0 in H (3.8 cm × 16.5 cm × 2.5 cm), and it weighs 2 lb 9.6 oz (1.2 kg). The 8000-RDI-332 is listed as discontinued by the manufacturer, but used and refurbished units remain available from distributors. This 32-channel digital input module is commonly used to expand input capacity for legacy control configurations or to retrofit older SY\/MAX I\/O installations to Spectrum Controls systems, enabling straightforward binary input monitoring for a wide range of industrial sensors and switch signals.\u003c\/p\u003e\u003c\/div\u003e","brand":"SPECTRUM","offers":[{"title":"New","offer_id":46259703054570,"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-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/spectrum-controls-8000-rdi-332-digital-input-module","provider":"GTG Hardware","version":"1.0","type":"link"}
