To maintain signal integrity, the board provides optical isolation at the TCDA interface, ensuring that field-side transients do not propagate to the control logic. The CPU on the associated TCDA board performs status monitoring with a 1 ms resolution time stamp for state changes. While the board itself is a passive termination component lacking firmware flash compatibility, its operation is dictated by physical jumper configurations that set interrogation voltage and isolate field grounds. I\/O density scaling is achieved through eight-contact input groupings, allowing for precise mapping of contact sense inversion within the TCDA I\/O configuration.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the interrogation voltage be changed from 125 VDC to 24 VDC in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. The excitation voltage option is factory-set. Field adjustments to jumpers on the DTBA\/DTBB boards are intended solely for isolating field grounds by cutting off interrogation voltage and must only be performed when the turbine is offline.\u003c\/p\u003e\n\u003cp\u003eQ: How is a failure in the contact input circuit detected?\u003c\/p\u003e\n\u003cp\u003eA: The Mark V LM controller performs continuous diagnostic checks on the input circuitry. If a circuit failure is detected, the system triggers an internal alert to the operator interface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eEnsure the Mark V LM system is fully de-energized and verified via lockout\/tagout (LOTO) procedures before accessing the terminal board or modifying jumper configurations.\u003c\/li\u003e\n\u003cli\u003eVerify that input configuration (125 VDC vs 24 VDC) matches the field device specifications to prevent damage to the optical isolators on the TCDA board.\u003c\/li\u003e\n\u003cli\u003eHandle the module by the edges and use ESD-protected tools to prevent damage to the sensitive input groupings.\u003c\/li\u003e\n\u003cli\u003eWhen isolating field grounds via jumpers, ensure the turbine is completely stationary; any adjustments to these jumpers during active operation may result in loss of input monitoring and subsequent system trips.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":53039080702261,"sku":"DS200DTBAG1A","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/DS200DTBAG1AAA_7f8ffe4c-b1c7-470f-9e85-cebf7263764f.jpg?v=1782459272","url":"https:\/\/www.5gplc.com\/products\/ge-ds200dtbag1a-digital-contact-terminal-board","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
