Channelized signal paths (covering signal numbers 1 through 45) pass directly to the connected TCQA board, preserving rapid signal propagation without intermediate processing delays. This fixed hardware pathway maintains full firmware flash compatibility and sustained backplane bus communication velocity across triple-redundant Mark V turbine controller racks.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Are there hardware jumpers on the DS200TBQAG1A board to configure thermocouple input types?\u003c\/p\u003e\n\u003cp\u003eA: No, the DS200TBQAG1A features a jumper-less design; all signal routing and configuration are handled via the connected TCQA board and system software.\u003c\/p\u003e\n\u003cp\u003eQ: How are the 20-pin ribbon cable connectors assigned on the DS200TBQAG1A board?\u003c\/p\u003e\n\u003cp\u003eA: Connectors JAR, JAS, and JAT interface directly with the TCQA board, each routing distinct subsets of thermocouple signal channels 1 through 45.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize all power sources to the Mark V rack and isolate field thermocouple circuits before opening the enclosure.\u003c\/li\u003e\n\u003cli\u003eLabel each connected field wire with its designated terminal number on TB1 or TB2 prior to removal.\u003c\/li\u003e\n\u003cli\u003eLoosen screw terminals only enough to release field leads without fully backing out the terminal screws.\u003c\/li\u003e\n\u003cli\u003eGrasp ribbon cable connectors exclusively by their plastic headers when unplugging from JAR, JAS, and JAT; pulling directly on ribbon cables can sever individual conductors.\u003c\/li\u003e\n\u003cli\u003eSupport the board securely with one hand while loosening the five rack-mounting screws, as the assembly carries added weight from the dual 90-pin terminal blocks.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":43913520513114,"sku":"DS200TBQAG1A","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/DS200TBQAG1ABB_0fe5c072-afe5-4360-a7e6-886a048194e2.png?v=1787714733","url":"https:\/\/www.spareoil.com\/products\/ds200tbqag1a-ge-mark-v-rst-terminal-board","provider":"SpareOil Automation","version":"1.0","type":"link"}
