{"product_id":"abb-3hne-05281-1-barrier","title":"ABB 3HNE 05281-1 Barrier","description":"\u003cdiv\u003e\u003cp\u003eABB 3HNE05281-1 ZB-03 Zener Barrier is an intrinsically safe barrier module used with ABB S4PPlus control systems to safely isolate end‑of‑arm tooling and sensors from hazardous-area circuits. It supports a maximum system voltage of 250 V (Um) and provides an output current of 105\/121 mA (Io) with a dissipation of 0.4\/0.7 W (Po). The barrier accepts an input supply of +12 V to −18 V (Un) and is rated for ambient temperatures up to 60 C (Tamb). Protection is specified as Ex Ib for IIb\/Iic gas groups and, when configured for Division 1 service, serves Cl.I, II, III environments. The device is identified by ABB part number 3HNE05281-1 and is commonly referenced as ZB-03, with a barrier resistance around 209\/294 Ω (Rt) and related documentation such as drawing 3HNE06150-1. Weight is typically around 0.5 kg. It is used in robot end-of-arm tooling safety circuits to ensure intrinsically safe operation in hazardous areas.\u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46257363845354,"sku":null,"price":61.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-085.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/abb-3hne-05281-1-barrier","provider":"GTG Hardware","version":"1.0","type":"link"}
