MikroElektronika has introduced the MIKROE-5597 RS485 Isolator 3 Click, a compact add-on board designed to provide enhanced electrical isolation and signal conditioning for RS485 communication systems. This board incorporates the ADM2763E, a 5.7 kVRMS signal-isolated RS485 transceiver manufactured by Analog Devices.
The ADM2763E transceiver is engineered to excel in low-speed communication over extended cable lengths, boasting a maximum data rate of 500 kbps. Its robust design includes protection against electrostatic discharge (ESD) events, withstanding ≥±12 kV contact and ≥±15 kV air IEC 61000-4-2 discharge levels on the RS485 A, B, Y, and Z pins. Conveniently accessible via screw terminal blocks, these pins ensure secure connections.
A notable feature of the RS485 Isolator 3 Click is its receiver cable invert pin, enabling swift correction of reversed cable connections on the A and B receiver bus pins while maintaining complete receiver fail-safe performance. Additionally, the board incorporates built-in fail-safe mechanisms for bus idle conditions, enhancing overall system reliability.
This add-on board is well-suited for a wide range of industrial and automation applications that demand insulation against working voltages of 1060 VRMS and 1500 VDC throughout the device's operational lifespan. Furthermore, it is supported by a mikroSDK-compliant library, offering developers a suite of functions to streamline software development.
In conclusion, MikroElektronika’s MIKROE-5597 RS485 Isolator 3 Click is a thoroughly tested and reliable solution, ready for integration into systems equipped with the mikroBUS™ socket. Its robust design, comprehensive protection features, and fail-safe functionality make it an excellent choice for enhancing signal isolation and conditioning in RS485 communication systems.
