Module Specifications
The F2-04THM, 4-Channel Thermocouple Input Module
provides the following features and benefits:
•
Four thermocouple input channels with 16-bit voltage
resolution or 0.1°F/°C temperature resolution.
•
Automatically converts type E, J, K, R, S, T, B, N, or C
thermocouple signals into direct temperature readings. No
extra scaling or complex conversion is required.
•
Temperature data can be expressed in °F or °C.
• Module can be configured as ±5V, ±156mV, 0–5V,
0–156mV input and will convert volts and millivolt signal
levels into 16-bit digital (0–65535) values.
•
Signal processing features include automatic cold junction
compensation, thermocouple linearization, and digital
filtering.
•
The temperature calculation and linearization are based on
data provided by the National Institute of Standards and
Technology (NIST).
•
Diagnostic features include detection of thermocouple
burnout or disconnection.
The following tables provide the specifications for the F2-04THM Analog Input Module.
Review these specifications to make sure the module meets your application requirements.
One count in the specification table is equal to one least significant bit of the analog data value
(1 in 65535).
