Page 4: Main Features
31 devices and a length equal to the main bus. The RHP303 regenerates the electric signal in one channel and transfers it to all the others (chicken foot topology). -
Page 5: Areas Of Application
1200m per segment. Figure 2 – General application Profibus DP networks can be expanded in tree or star topology, without limits for RHP303 in cascade. See the next figure. -

Page 8: Installation
The RHP303 can be installed anywhere in a non-hazardous area and on the specified temperature range of 0 to 60ºC. The RHP303 must be installed on DIN rail, with the connector cable on the bottom part. In this position the cables go down and it is also easier to read the status LEDs. -
Page 9: Power Supply
PROFIBUS Engineer certificate. Power supply The power supply connector, a 3-pin terminal block, is located on the RHP303 lower left corner. The power supply must comply with the Technical Specifications topic. Figure 9 – Detail of the power supply connector... -
Page 10: Baud Rate Configuration
Terminators All RHP303 channels have configurable terminators. The main channel termination is adjusted in OFF by default. If the RHP303 is the last or the first segment device, the termination must be adjusted in ON. The termination of the other channels is adjusted in ON by default because the new segment is expected to be initiated on the RHP303. -
