Industrial Radio Frequency Communication IoT Gateway
ModProBus RTU-P series modems are designed for industrial automation and smart agriculture applications. With RS232 and RS485 ports, they provide secure and fast wireless radio frequency communication between many industrial machines, HMI panels, and PLCs. Thanks to the I/O connection point, you can perform digital I/O operations directly on the modem without the need for an additional device using the Modbus RTU protocol.
