The EX9043 has 8 digital inputs and 4 digital open-collector outputs.
The module is connected via the RS-485 interface and can be easily configured with the integrated development environment (IDE) as an I/O extension. The I/O extension is fully transparent for the application. The inputs and outputs of the Modbus module can be used in the same way as the ones present in the telecontrol unit. No further configuration equipment is required.
