DESCRIPTION:
ISO 4-20mA Current Loop Isolation Interface IC provides signal receive and transmittal on a
Single chip. The ceramic hermetic hybrid package contains an electromagnetic coupled converter
And current modulate. The very low input equivalent impendence allows the input voltage can be
Up to an ultra-wide range (7.5V~32V), so that it is able to meet the requirements for no distortion
In long-distance signal transmission under the circumstance of no outside connecting power. The
Internal ceramic PCB, printed impendence and new isolation technologies allow the IC for the
3KVAC insulated voltage and meets the industrial level for the extremely poor temperature,
Humidity and shaking conditions.
