9 TEMPERATURE SENSOR DAUGHTER BOARD
This chapter describes the single and dual temperature sensor boards.
9.1 Overview of the temperature sensor board
The iTC can accept the following sensor types:
• Negative temperature coefficient (NTC) resistance
• Positive temperature coefficient (PTC) resistance
• Thermocouple
• Silicon diode
Each input can be read at a maximum rate of 10 Hz. The iTC can detect short-circuit inputs,
open-circuit inputs, and inputs that are shorted to ground.
The MercuryiTC contains a temperature sensor that is used to compensate for fluctuations in
ambient temperature.
9.2 Installing a temperature sensor board
9.2.1 Fitting the board
If a temperature board is not used to control a heater, it can be fitted in any expansion slot. It is
preferable to locate temperature boards in slots that are physically separated from any heater
boards present.
If a temperature sensor board is to be used to control a heater, it must be fitted in the correct
slot, as shown in the following table.
Heater board output Temperature sensor board
Slot 1 is connected to Slot 6
Slot 2 is connected to Slot 7
Slot 3 is connected to Slot 8
The procedure for fitting a daughter board has already been described in section 5.2.
