Each channel can be software-configured as a digital input or counter and channels 1 and 2 support high-speed counting with front-panel switches that select different RC values for the low-pass filter. The DI-8 includes input protection with a 0.5 A resettable fuse, transient voltage suppression (TVS), and reverse-polarity protection to guard against wiring errors and transients. It communicates over the Continuum I\/O network (RS-485 variant), with input conditioning referenced to a 5 V logic domain for reliable operation in commercial installations. Typical applications include equipment-status monitoring and alarm-point monitoring, and the module is designed to integrate with other Continuum I\/O modules to provide a scalable, cost-effective digital input solution for building automation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Andover","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660009767214,"sku":null,"price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_57a065dd-7d38-42c3-ab23-cd877164a2b7.jpg?v=1769531715","url":"https:\/\/plgautomation.com\/products\/andover-controls-corporation-di-8-digital-input-module","provider":"PLG Automation ","version":"1.0","type":"link"}
