Supply Coupling Unit
The supply coupling unit is mainly used in those applications, where multiple Dupline® modules of the type G21...700 are to be supplied through a DC-bus. Since these modules use the same wire for the common of the transmission signal and the “minus” of the DC-supply, the G 3485 000 assures proper coupling of the supply to maximise the noise immunity of the entire installation. To supply a current ≤ 4 A (up to 25°C) / ≥ 3 A (under 50°C), multiple coupling units may be installed in parallel.
Features
• For systems using a combined communication-supply bus (3-wires)
• Input from a standard 15... 30 VDC power supply
• Coupling of transmission- and supply-common
• Output current 4 A max.
• H4-housing
