In most Yokogawa DCS configurations, you can replace the backup battery while the controller is receiving primary power.

The black plug is a specific connector key for certain Yokogawa series controllers. Always verify that your current battery uses the same black connector and voltage (2.4V) before installation to ensure 100% hardware compatibility.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43194958086234,"sku":"S9129FA","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/205_da46e256-ec84-4b8e-8671-3137d2f44b1e.jpg?v=1775722142","url":"https:\/\/www.spareoil.com\/products\/s9129fa-yokogawa-plc-battery-for-centum-vp-cs-3000","provider":"SpareOil Automation","version":"1.0","type":"link"}
