Module Calibration
The F2-04THM module requires no calibration. The module automatically calibrates every
five seconds, which removes offset and gain errors. For each thermocouple type, the temperature
calculation and linearization performed by the microprocessor is accurate to within 0.01°C.
Thermocouple Input Configuration Requirements
The F2-04THM module requires 32 discrete input points from the CPU. The module can be
installed in any slot of a DL205 system. The limitations on the number of analog modules are:
• For local and local expansion systems, the available power budget and number of discrete I/O
points.
• For remote I/O systems, the available power budget and number of remote I/O points.
Check the user manual for the particular model of CPU and I/O base being used for more
information regarding power budget and number of local, local expansion or remote I/O
points.
