USER GUIDE
SCC-TC Series Thermocouple
Input Modules
The SCC-TC Series thermocouple input modules, SCC-TC01 and
SCC-TC02, accept input signals from B-, E-, J-, K-, N-, R-, S-, and T-type
thermocouples. Each module contains thermistor circuitry powered by
2.5 V, to compensate for cold-junction effects and can detect open
thermocouple circuits. Each module has one thermocouple input channel,
which consists of a gain of 100 differential amplifier and a dual-pole 2 Hz
filter.
Note Alternatively, you can use the SCC-TC02 as a 2 Hz lowpass bandwidth ±100 mV
input module.
