The transceiver employs giant magnetoresistance technology to provide galvanic isolation that keeps the communication bus free from common-mode noise generated in electrically noisy factory and building automation environments.
The ISL32704E is suited to equipment-to-bus interface in IIoT networks that connect programmable logic controllers to instruments, robots, motor drives, data acquisition and digital I/O modules.
The device’s GMR isolation is claimed to have low radiated emission and low EMI susceptibility, and does not require elaborate encoding schemes.
According to the company, the ISL32704E offers 80% less power consumption than competing devices because it doesn’t use power hungry transfer coils or transformers. It also provides 600V RMS of working voltage.
On the non-isolated control-side, the transceiver supports direct connection to a 3V MCU while the isolated bus-side connects to a higher voltage 5V supply for communication of strong bus signals across 100m and longer distances.
The ISL32704E is fully compliant with the EN 50081 and EN 50082-2 electromagnetic compatibility standards and the umbrella line-voltage standard for information technology equipment EN 61000.
