It uses a fiber-optic communications port to connect remote I\/O to Mirrored Bits-capable devices, enabling teleprotection and secure local\/remote signaling without modifying the control panel face. The unit ships as SEL-2506-250603114X and supports a flexible power setup, including a 125 V DC I\/O supply and an external power option for 48\/125 VAC or DC, accommodating a range of substation power architectures. For field connectivity, standard fiber transceivers in the SEL fiber family are compatible, supporting multimode and single-mode links as needed by the installation. This makes the 2506 ideal for adding local trip\/close-coil monitoring, expanding relay I\/O, and enabling high-speed, secure I\/O expansion in protection schemes across remote locations. \u003c\/p\u003e\u003c\/div\u003e","brand":"SEL","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46283481481450,"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-020.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schweitzer-engineering-laboratories-250603114x-remote-io-module","provider":"GTG Hardware","version":"1.0","type":"link"}
