Signal Conditioner Cards, which interface to the process, are installed in Signal Conditioner Nests.
The signal conditioner cards can convert the I/O signals, isolate the I/O signals, and provide an isolated power supply from a built-in distributor.
For example, the measuring ranges of temperature and mV input signal conditioner cards can be changed by a portable BRAIN terminal. Some cards have communication functions and supply power to BRAIN Series transmitters (BRAIN UNI∆, BRAIN ADMAG and BRAIN YEWFLO).
