In supplier listings it appears as CS-538-000B with Rev. 2 and is cross-referenced under alternate assembly numbers such as 7002056, sometimes shown as 7002056-1, with several sources labeling the board LS-REV.2 to indicate the same revision. This PCB functions as the CPU within legacy Bell \u0026amp; Howell PLC systems and is commonly offered for repair, replacement, or refurbishment of older automation equipment. The CS-538-000B designation identifies a specific CPU board within the CS-538 family, and the Rev. 2 labeling helps match it to compatible catalogs and backplane configurations used in Bell \u0026amp; Howell control architectures. Third‑party vendors and marketplaces frequently list this part as a used or remanufactured Bell \u0026amp; Howell PLC component, reflecting its role in sustaining legacy installations that rely on CS-538-based hardware.\u003c\/p\u003e\u003c\/div\u003e","brand":"Bell","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676872605998,"sku":null,"price":377.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_96693faf-aca4-4e0a-9064-e71576549801.jpg?v=1769554601","url":"https:\/\/plgautomation.com\/products\/bell-and-howell-cs-538-000b-cpu-board-for-programmable-logic-controller","provider":"PLG Automation ","version":"1.0","type":"link"}
