Analog-input-module, RTD, 16 Bit
1 / 2x R
Analog input modules for the modular fieldbus IO system TB20.
Note: Individual modules cannot be combined with IO systems from other manufacturers.
The scope of delivery already includes the appropriate front connector for the cabling and a base module. The module has 1 to 2 analog inputs for RTD resistance measurements, depending on whether the wiring is 2 / 3 / 4 wire.
