The board is treated with a conformal coating to protect the surface-mount components from humidity, dust, and corrosive airborne contaminants typical of industrial turbine environments. As a terminal board, it does not actively manage backplane bus communication velocity; rather, it ensures signal integrity for the connected I\/O processor. Firmware flash compatibility is governed by the host I\/O pack, which performs the cold junction compensation (CJC) calculations based on the signals routed through this terminal board. Deterministic I\/O density scaling is achieved by utilizing multiple TBTC boards to increase the total number of monitored thermocouple points within a single control cabinet.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is this terminal board active or passive?\u003c\/p\u003e\n\u003cp\u003eA: The IS200TBTCH1B is a passive terminal board. It provides mechanical connectivity for field wiring and routes signals to the I\/O processor; it contains no active logic or processing components.\u003c\/p\u003e\n\u003cp\u003eQ: Can this board be used with RTD sensors?\u003c\/p\u003e\n\u003cp\u003eA: No. The terminal board is specifically designed for thermocouple inputs. RTD sensors require different input scaling and signal processing logic, which would result in inaccurate data if connected to a TBTC board.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Secure the PCB in the designated Mark VI cabinet location.
