It operates from 100 to 240 VAC and accepts a universal input range including thermocouples (types B, E, J, K, N, R, S, T), Pt100 RTD (3‑wire), and signals such as 0–20 mA\/4–20 mA or 0–60 mV, 0–5 V, or 0–10 V, with square‑root extraction and keyboard‑programmable 9‑segment linearization. Two alarm outputs are independently configurable, and optional features include RS‑485 serial communication and various retransmission or auxiliary power options (5, 10, 12 or 24 Vdc). The front panel is IP54 rated, and the enclosure uses a PC\/ABS black housing with a two‑color display showing four numeric digits, two alphanumeric characters, and six status LEDs to convey measurement and alarm information at a glance. \u003c\/p\u003e\u003c\/div\u003e","brand":"Barber","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676663808302,"sku":null,"price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9a3e888c-595a-4076-87ee-0efd145ef639.jpg?v=1769552098","url":"https:\/\/plgautomation.com\/products\/barber-colman-7hl391110000-indicator-and-alarm-unit","provider":"PLG Automation ","version":"1.0","type":"link"}
