Physical Layout and Component Arrangement
The GE IS200VTCCH1B IS200VTCCH1BBB thermocouple input board uses a rigid epoxy substrate. Six isolation amplifiers occupy the upper section of this board. One high-resolution ADC chip sits below these amplifiers. Four storage capacitors provide power filtering for stable operation. Two backplane connectors anchor this board securely into the Mark VI rack. A front terminal block accepts thermocouple wiring directly.
Functional Features and Integration
This thermocouple board applies cold junction compensation using an internal temperature sensor. It rejects common-mode noise through its isolated amplifier design. The GE IS200VTCCH1B IS200VTCCH1BBB also includes open-thermocouple detection on every channel. Consequently, it alerts the control system immediately when a sensor fails.
Installation and Safe Handling
Always use proper thermocouple extension wire for field connections. Hold the GE IS200VTCCH1B IS200VTCCH1BBB firmly by its non-conductive edges. Push the board straight down until both backplane connectors lock into place. Then connect each thermocouple pair to the correct terminal positions. After installation, verify each channel reading through the Mark VI software interface.
