Industrial Applications

Primary Purpose


Electrically Isolate the Controller Area Network Communication
Links in Industrial Automation Control and Instrumentation


Protect equipment from damaging surges/spikes


Eliminate down time when using non
-
isolated ports


Safety certification required (i.e., UL, CSA, VDE, etc.)



Key Difference between ADM3052 & ADM3053


How the power supply is configured


ADM3052


4 wire bus configuration with 24V power over the bus


ADM3053


2 wire bus configuration with power from logic side of device.



Customer Benefits
