Wireless Modbus I/O pair

Conlab has available the RT12-4411 iWireless I/O pair with built-in Modbus protocol and ethernet port.

The device is an accurate wireless system designed to convert wired sensors into a wireless connection between 4-20 mA, 0-5 VDC or 0-10 VDC analog inputs and 0-5 VDC analog outputs wired to PLC, data logger or SCADA system.

The device is equipped with four channels of bidirectional, full duplex 12 bits analog inputs and outputs and one optically isolated digital input and open collector digital output. The hardware for both master and slave is identical.

The four input signals from the master and slave are transmitted to each other and are converted for their respective outputs. Power requirement is 12-24 VDC with battery charger built in. In addition, each module can be reconfigured as a standalone standard wireless Modbus remote I/O device accessible through its built-in radio by any Modbus-based system and a licence-free radio.

The unit generates alarms when communications are lost or when input voltage is too high. The built-in long-range radio is based on spread spectrum frequency hopping technology communicating over 915 and 928 MHz or 2.4 GHz. Optional programming software is available enabling data to be displayed in graphic and numeric format including engineering units.
