Analog-input-module, RTD, 16 Bit
8x 2 wire
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 8 analog inputs for RTD resistance measurements with 2 wire.
