RS485 Modbus RTU Slave Module with RJ45
The IS4310-485M2 is a ready-to-operate module integrating the Modbus RTU Slave stack chip IS4310 with an RS485 Transceiver.
This solution reduces to the minimum expression the design effort of integrating a Modbus RTU Slave with RS485 electrical interface.
The module is daisy-chained: it integrates two RJ45 connectors with the standard Modbus pinout.
Also, it has the power pin routed. With this feature, you can design a self-powered Modbus Slave.
The module can be directly soldered to your PCB with its castellated holes, or you can solder a pin header and use it as a module.
