{"product_id":"banner-engineering-opba2qd-power-block","title":"Banner Engineering OPBA2QD Power Block","description":"\u003cdiv\u003e\u003cp\u003eThe Banner Engineering OMNI-BEAM OPBA2QD Power Block is a modular AC-powered block designed to accompany OMNI-BEAM sensors, supplying 105-130 V AC and providing two independent outputs: channel A (load) and channel B (alarm) through solid-state switching. The QD variant integrates a standard 5-conductor quick-disconnect cable fitting for fast field wiring, simplifying connections without a separate harness. The block uses SCR-based solid-state output circuitry to drive AC loads and offers an on-state voltage drop under 2.5 V AC at full load with off-state leakage current typically under 100 µA, supporting reliable performance in AC-load applications. In Banner’s documentation, OPBA2QD is listed as obsolete, with guidance to select a suitable replacement for new designs, though it remains compatible with existing OMNI-BEAM configurations. In typical use, the A output carries the sensor head’s load signal while the B output provides an alarm signal, both powered by the same 105-130 V AC supply managed by the power block. The OPBA2QD is part of Banner’s OMNI-BEAM power-block family, offering straightforward wiring and distinct signaling paths for load and alarm in AC-powered sensing applications such as automated manufacturing lines and process monitoring. \u003c\/p\u003e\u003c\/div\u003e","brand":"Banner","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676553543982,"sku":null,"price":815.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2ae03f98-3757-41a9-ad43-b9b4c91816b3.jpg?v=1769551497","url":"https:\/\/plgautomation.com\/products\/banner-engineering-opba2qd-power-block","provider":"PLG Automation ","version":"1.0","type":"link"}
