transparent current supply isolators
The ACT20X-HAI-SAO current supply isolator is a HART
®
-protocol transparent signal isolator for analogue
input signals from Ex zone 0. It provides an analogue signal for the safe zone on the output side. 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
