It represents the baseline hardware specification for the Mark V DTBC series.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this board support both 125 VDC and 24 VDC inputs?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: While the Mark V system often uses 125 VDC for contact wetting, the DS200DTBCG1AAA is primarily designed for the standard voltage rails established in the Mark V power distribution. Check your specific unit wiring diagram (W\/D) for exact voltage compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I swap this board while the turbine is running?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: We strongly advise against \"hot-swapping\" terminal boards. Disconnecting field wiring or ribbon cables while the system is energized can cause unpredictable turbine trips or damage to the I\/O processors. Only perform hardware replacements during a scheduled outage or in a \"Ready to Start\" state with control power isolated.\u003c\/p\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":53455767371960,"sku":"DS200DTBCG1AAA","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6132\/3704\/files\/DS200DTBCG1AAA_2_1.jpg?v=1778568285","url":"https:\/\/www.globalpetroparts.com\/products\/mark-v-digital-terminal-board-ge-ds200dtbcg1aaa","provider":"Global Petro Parts Automation","version":"1.0","type":"link"}
