Product description

The G303 operating device combines the features you would expect from a high-end device with a very attractive price. The G303 can communicate with a wide variety of devices that have a high-speed RS232/485 interface or an Ethernet 10 BaseT / 100 Base-TX network connection. Thanks to the internal high-speed protocol converter, different control systems can exchange data via the operating device without a gateway. The additional USB interface allows projects to be downloaded quickly and stored data to be read out quickly. The integrated Compact Flash socket allows the installation of a Compact Flash card to record measured data or trends, as well as to store extensive projects. In addition, all common bus systems, such as Profibus, CANopen, DeviceNet, Modbus, BACnet, are supported.
The web server function can be activated simply by clicking in the checkbox in the project planning software. Once activated, you can access all data from the operating device via the Internet/intranet. The LCD display is fully graphics-capable and can also be read in sunlight. The user can access a wide variety of configured functions via the 32 membrane keys. In addition to the 3 freely programmable function keys that allow direct access to screen contents, the 3 LED status indicators can also be freely programmed to display statuses.
