Technical Specifications of GE IS200VTCCH1C IS200VTCCH1CBB

Component Count and Board Construction

This GE IS200VTCCH1C board contains over 200 discrete components on its surface. You will find multiple high-precision operational amplifiers for signal conditioning. Furthermore, the board includes a dedicated cold junction compensation sensor. The assembly also features optical isolation for each input channel.

Interfaces, Energy Storage, and Signal Processing

The IS200VTCCH1CBB revision provides a front-face terminal block for thermocouple wiring. Moreover, the board uses capacitors for input filter networks. These capacitors store minimal energy but reject 60 Hz noise effectively. Each channel includes a 24-bit analog-to-digital converter for high resolution.

Functional Logic and Application Context

This Mark VI board samples all eight thermocouple inputs at 10 Hz continuously. It then converts microvolt signals into linearized temperature readings. The GE IS200VTCCH1C performs automatic cold junction compensation for each channel. Additionally, it detects open thermocouple conditions and reports sensor failures. Consequently, the board ensures reliable temperature monitoring in harsh environments.

Channel Configuration and Burnout Detection

You can configure each channel for a specific thermocouple type independently. The board provides built-in burnout detection for broken sensor wires. Furthermore, the IS200VTCCH1CBB applies software linearization tables for accuracy. This linearization covers the full temperature range of each sensor type. The board also includes averaging filters for noise reduction on critical channels.

Installation and Environmental Limits

You must power down the VME rack before inserting this thermocouple board. The operating temperature range spans 0°C to 60°C . Furthermore, the board provides 1500 V isolation between inputs and logic. Always verify the IS200VTCCH1CBB channel configuration before connecting sensors.
