Power consumption and perm. voltage drop with one actuator

With AC supply, the G0 line has a AC 0.21 A supply current and a DC 0.1 mA positioning signal current (from Y = DC 0...10 V). The AC voltage drop on the G0 line does not impact the positioning signal Y.

P&I diagram:
Conduction currents at AC 24 V

The diagram shows the currents in the connecting lines for one actuator.

Example:
Parallel connection of four actuators

Determining the line lengths for four actuators GMA16..1 at AC 24 V supply. Only the AC currents in line 1 (G) and 2 (G0) determine the line sizing.

Max. permissible voltage drop = 4% per line.

  • Consumption: 4 x 5 VA = 20 VA

  • Line current: 4 x 0.21 A = 0.84 A

  • Permissible single line length for G, G0:

    98 m at 1.5 mm2 line cross section, or
    163 m at 2.5 mm2 line cross section.
