4-14 Remote Control PAS SERIES
4.1.5 Controlling the Output Current Using External
Resistance
This method is used to control the output current using an external
resistance (Rext) in the range 0 kΩ to approx. 10 kΩ.
Press the SET switch to check the preset current.
• The insulation of the external resistor (Rext) and the
cable connecting it should be greater than the isola-
tion voltage of the unit. For details on the isolation
voltage of each model, see Chapter8 "Specifica-
tions".
• When using shielded wires for connection, protect
the uncovered section of the shielded wire by using
insulation tubes with a withstand voltage greater than
the isolation voltage of the unit.
You can select the following two types of modes through CONFIG
settings. For details on CONFIG settings, see "3.2.4 Unit Configura-
tion (CONFIG)".
10 kΩ → MAX OUT CC mode
The output
current (Io) varies in the range of 0 to rated output cur-
rent by
setting the external resistance (Rext) in the range of 0 kΩ
to 10 kΩ.
Io = Irtg•Rext /10 [A] Rext = 10•Io /Irtg [A]
Irtg: Rated output current [A]
10 kΩ → 0 OUT CC
mode (F
AIL SAFE)
The output current (Io) varies in the ra
nge of rated output current
to 0 by setting the external resistance (Rext) in the range of 0 kΩ
to 10 kΩ.
Io = Irtg•(10-Rext)/10 [A] Rext = 10•(Irtg-Io)/Irtg [A]
Irtg: Rated output current [A]
