Applications - Industrial automation equipment - Grid infrastructure - Solar inverter - Motor drivers - HVAC 3. General Description The CA-IS2082B device is a galvanically-isolated RS-485 transceiver that has superior isolation rating and RS-485 performance to meet the critical needs of the industrial applications. This device has the logic input and output buffers separated by a silicon oxide (Si O2) insulation barrier that provides galvanic isolation, Features up to 3000VRMS (60s) of galvanic isolation and ±100k V/μs typical CMTI. Isolation improves munication by breaking ground loops and reduces noise where there are large differences in ground potential between different...
