Analog-input-module, TC, Iso., 16 Bit
4x
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 4 analog inputs for connecting thermocouples.
