Technical Specifications of GE IS200WETCH1A IS200WETCH1APR2

Component Count and Board Construction

The GE IS200WETCH1A board contains over 200 discrete components. 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. Each channel uses a 24-bit ADC for high resolution.

Interfaces, Energy Storage, and Signal Processing

The IS200WETCH1APR2 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 dedicated analog-to-digital converter. The cold junction sensor maintains accurate reference temperature.

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 IS200WETCH1A 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 IS200WETCH1APR2 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 WETC 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 IS200WETCH1APR2 channel configuration before connecting sensors. Use proper thermocouple extension wire for accurate readings.
