This product is used to extend I/O capabilities of the CT1820 and MSB764T, but can also be used as a Modbus slave for any RS-485 Modbus capable application. 

No programming required!  Just connect a Modbus master via RS-485, set the Modbus slave address of each module, and it just works.

A wide variety of modules are available so you can configure your system specifically to your application's needs.
