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.

We find communication protocols beautiful.
Implementing them as stacks inside chips connects us to the mindset of the engineers who designed them. You can feel the passion they put into solving communication challenges — whether it's for industrial systems, lighting, or sound.
But when you're building your own project, diving into protocol implementation can eat up a lot of engineering time (or your client's budget!).
So why not save that time and focus on what truly makes your product unique — instead of reinventing the wheel?
