It operates from 120 VAC (50\/60 Hz), draws 6.8 VA, and provides a 5 A, 120 VAC relay output to trigger alarms or shut down equipment when a monitored parameter exceeds the preset limit. Designed for use with the LFE Analog Optical Meter Relay Series (Factory Style #3), this unit forms the control core in process monitoring, alarm indication, and automation applications. Typical installations include manufacturing facilities, power generation, water and wastewater treatment plants, HVAC systems, and other industrial automation setups requiring automatic high-limit switching. Maintenance technicians, instrumentation engineers, and system integrators rely on it for equipment repair, process control retrofits, and replacing failed relay modules to restore reliable high-limit monitoring. The product is discontinued by the manufacturer, with common replacements including LFE 8889-2003, 8889-3003, and 8889-0001.\u003c\/p\u003e\u003c\/div\u003e","brand":null,"offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46252653150442,"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-006.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-8889-0003-meter-relay-control-unit","provider":"GTG Hardware","version":"1.0","type":"link"}
