9.3.4 Status/Temp Board

The Status/Temp Board is a multifunction board that:
1. Converts the resistance readings of the thermistors to voltages
2. Provides status output circuitry
3. Provides circuitry for contact closure inputs
4. Provides circuitry for display brown-out/reset at low line voltage
5. Provides sockets for voltage-to-current modules
9.3.4.1 Temperature Amplifier Section
The Status/Temp board is a multifunction board consisting of 4 thermistor amplifiers that
monitor:
1. IZS temperature
2. Reaction Cell temperature
3. Box temperature
4. Spare
The voltages of the thermistor and thermocouple amplifier outputs are brought out to test points
on the edge of the board. The voltages can also be read using the DIAGNOSTIC - SIGNAL I/O
feature (see Table 9-4 for details).
Thermistor Temperature Amplifier Adjustments
The Status/Temp board has 3 thermistor temperature amplifiers:
1. Reaction Cell Temperature
2. IZS permeation tube heater
3. Box temperature readout
