The board’s TMR rating enables fan‑out of contact inputs and relay outputs to three independent PDIO packs, maintaining synchronous timing across R\/S\/T control paths. Firmware flash compatibility resides entirely in the PDIO pack; the TDBT board contains no programmable logic. I\/O density scaling is achieved through fixed hardware design—no jumpers or configurable elements—ensuring predictable mapping across legacy and upgraded Mark VI installations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Where was the IS230TDBTH6A originally manufactured?\u003c\/strong\u003e A: The board was produced at GE’s Salem, Virginia manufacturing facility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the board support simplex operation?\u003c\/strong\u003e A: No. The IS230TDBTH6A is designed for TMR operation and provides triple fan‑out to PDIO packs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are there any configurable jumpers on the board?\u003c\/strong\u003e A: No. The board is fully fixed‑configuration and contains no jumper‑selectable hardware.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the board on a DIN rail or sheet‑metal carrier according to cabinet layout requirements.\u003c\/li\u003e\n\u003cli\u003eMaintain proper isolation between contact input wiring and high‑energy conductors to reduce surge coupling.\u003c\/li\u003e\n\u003cli\u003eEnsure TB1 and TB2 barrier‑type terminal blocks are fully seated before energizing the system.\u003c\/li\u003e\n\u003cli\u003eTerminate shields to the chassis‑mounted shield bar to minimize high‑frequency noise.\u003c\/li\u003e\n\u003cli\u003eVerify full seating of JE1, JW1, and JW2 connectors to maintain TMR synchronization.\u003c\/li\u003e\n\u003cli\u003eFollow GE installation manuals for torque values and grounding practices.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":48157628170430,"sku":"IS230TDBTH6A","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-06-30_10-39-10_f836a30a-3e2d-4f13-9c22-af061129e574.png?v=1782973173","url":"https:\/\/www.autooiltech.com\/products\/general-electric-is230tdbth6a-discrete-input-output-terminal-board","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
