FP-TB-10 Operating Instructions
Analog Thermocouple Input Modules
(FP-TC-J, FP-TC-K, and FP-TC-T)
The FP-TC-J, FP-TC-K, and FP-TC-T are dual-channel input
modules for J-, K-, and T-type thermocouples, respectively. These
modules provide 12-bit-resolution measurements, and each
channel can be programmed for either the °C or the °F scale. These
modules do not use the screw terminals of the FP-TB-10. Wire
your thermocouple signals to the thermocouple connectors on the
top of the module.
Note
If your application requires channel-to-channel
isolation, use only one channel of each module.

RTD Input Modules (FP-RTD-PT100,
FP-RTD-PT100-3, and FP-RTD-PT100-4)
The FP-RTD-PT100, FP-RTD-PT100-3, and FP-RTD-PT100-4
are dual-channel input modules for two-, three-, and four-wire
100
Ω
platinum RTDs respectively. They provide 12-bit-resolution
measurements. Each module is designed with the linearization
curves of a DIN 43760 standard RTD (
α
=
0.00385). Each channel
can be programmed for either the °C or the °F scale.
Note
If your application requires channel-to-channel
isolation, use only one channel of each module.
The FP-RTD-PT100 connects to two FP-TB-10 screw terminals
per channel. The “b” terminal is common for both channels. The
FP-RTD-PT100-3 has two sets of screw terminals on top and does
