It handles a DC current range of 10–50 A through a 1.50-inch diameter aperture, allowing a single conductor to pass through the sensing element for detection. The unit features a barrier interface for wiring and can be ordered with an optional 1.50-inch diameter split nickel-plated copper bus bar to route the conductor through the detector. Powered by +25 to +45 VDC, it provides a relay-style SPST output with automatic reset for signaling when the sensed current crosses the setpoint. The housing is a plastic case suitable for industrial environments, and a dual bus-bar option is available for larger current paths. Common applications include DC power-distribution monitoring and rail-transit ground-fault detection, where rapid current sensing and a discrete alarm signal are important. \u003c\/p\u003e\u003c\/div\u003e","brand":"AAC","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51656682799406,"sku":null,"price":1160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_cf0515a7-745b-464a-9041-d5a21acc96f4.jpg?v=1769462688","url":"https:\/\/plgautomation.com\/products\/aac-s623-50-dc-current-detector-module","provider":"PLG Automation ","version":"1.0","type":"link"}
