1. Introduction
PART 3 TC218
1. Introduction
The TC218 is a thermocouple input module for the T2 series programmable controllers.
The TC218 is used to measure the temperature using thermocouples. Thermocouples type K,
J, or E can be used.
The TC218 can be used for
The TC218 is used to measure the temperature using thermocouples. Thermocouples type K,

The TC218 can be used for
±
100mV input also.
When the TC218 is used for the thermocouple input, it has 7 channels of thermocouple input.
The remaining 1 channel is used to measure the ambient temperature for cold junction
compensation. For this purpose, a thermistor is attached with the TC218.
On the other hand, when the TC218 is used for
The remaining 1 channel is used to measure the ambient temperature for cold junction
compensation. For this purpose, a thermistor is attached with the TC218.
On the other hand, when the TC218 is used for
±
100mV input, it has 8 channels of input.
1.1 TC218 Functions
