It relies on the EMIO (Exciter Main I\/O) board to collect contact state data and relay control logic. The processed I\/O states are transmitted as logic-level gate pulse signals across the internal backplane to the ESEL board. This deterministic communication loop ensures that the trip contact outputs are processed within the defined scan time of the excitation control system. Firmare compatibility is managed at the system level via the EMIO interface, ensuring that the terminal board inputs remain mapped to the correct logical addresses in the ESEL control processor.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the IS200ECTBG2A be used in redundant system configurations?\u003c\/p\u003e\n\u003cp\u003eA: No. The G2 version of this board is specifically engineered for Simplex Mode. Redundant system architectures require the G1 board variant to support necessary dual-mode logic and signal voting.\u003c\/p\u003e\n\u003cp\u003eQ: How is the contact wetting voltage managed?\u003c\/p\u003e\n\u003cp\u003eA: The board receives an isolated +70 VDC supply directly from the associated EPSM module. This voltage is applied to the auxiliary contact inputs for monitoring purposes. Ensure no external voltage sources are applied to these input terminals to prevent damage to the isolation circuitry.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: The board must be mounted in a standard EX2100 cabinet slot. Ensure all captive fasteners are tightened to maintain electrical continuity between the board chassis and the cabinet ground plane.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: Auxiliary inputs (such as 52G and 86G) must be wired using shielded, twisted-pair cabling. Terminate cable shields at the designated cabinet grounding bar to mitigate electromagnetic interference that could cause erroneous contact state changes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Isolation\u003c\/strong\u003e: Prior to installation or cable termination, verify that the +70 VDC supply from the EPSM module is disconnected. Use a digital multimeter to confirm zero potential at the terminals before proceeding with wiring.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLogic Verification\u003c\/strong\u003e: After installation, verify the mapping of the 6 auxiliary inputs and 6 total relay outputs within the EX2100 system configuration software to ensure the logic-level gate pulses are correctly interpreted by the ESEL board.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":52949070250293,"sku":"IS200ECTBG2A","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/IS200ECTBG2A.png?v=1780300296","url":"https:\/\/www.5gplc.com\/products\/ge-is200ectbg2a-exciter-contact-terminal-board","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
