transparent current output isolators
The ACT20X-SAI-HAO current output isolator is HART
®
-transparent. The input is connected to the safe area
controller or PLC, and the output is connected to an analog actuator in a hazardous area, e.g. Zone 0. It is
available in a single-channel or double-channel version.
EX area Zone 0, 1, 2, 20, 21, 22 Safe area Zone 2 / FM Class 1, Division 2
