It provides automatic synchronization, load sharing, and high-speed power-system monitoring, and it measures 5 A full-scale current with a 100\/120 VAC sensing range. The unit supports three synchronization methods: PID control using the PLC-5 PID instruction, discrete I\/O signaling via LSM error outputs, and the clipped-gain method using BTR data tables, with update rates including bus-error parameter updates at about 100 ms and load-share\/monitor activity at about 200 ms when synchronization is inactive or about 1 s when active. It operates from 0 to 60 C and offers a dielectric withstand of 2500 V RMS, with backplane current draw of roughly 1.1 A at 5 V DC (2.2 A inrush). The 1402-LS51 is intended for retrofitting PLC-5 systems and is compatible with Allen-Bradley 1771 backplanes. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46279489487082,"sku":null,"price":950.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-077.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1402-ls51-line-synchronization-module","provider":"GTG Hardware","version":"1.0","type":"link"}
