The IS4310-232M4 is a ready-to-operate module integrating the Modbus RTU Slave chip IS4310 with an RS232 transceiver. This solution reduces to the minimum expression the design effort of integrating a Modbus RTU Slave with an RS232 electrical interface.
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.
