OUTLINE

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 b 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).

You can select from 16 types of cards according to the

kind of field signal.
