PROFIBUS 6kV VDE-Reinforced Isolated RS-485 Transceiver Evaluation Board


The ISL32740EVAL1Z board enables the evaluation of the ISL32740EIBZ isolated, half-duplex RS-485 transceiver in a typical bus node application, used in isolated industrial networks.

The ISL32741E is a galvanically isolated, high-speed differential bus transceiver, and provides 40Mbps bidirectional data communication for Industrial IoT networks. The device uses Giant Magnetoresistance (GMR) as its isolation technology.

The ISL32741E offers 1,000VRMS working voltage and 6kV of reinforced isolation, more than 2x higher than competitive solutions. The higher working voltage and reinforced isolation is required for today’s most rigorous medical and high-speed motor control applications. The ISL32741E is PROFIBUS compliant, including the rigorous PROFIBUS differential output voltage specifications.
