    R-Control for Output Voltage Adjustment
    Notes: With open R input,
    Uo
    ≈ U
    o nom. R excludes option P.
    As a standard feature, single output modules offer an
    adjustable output voltage identified by letter R in the type
    designation.
    The output voltage
    Uo1 can either be adjusted with an exter-
    nal voltage (
    Uext) or with an external resistor (R1 or R2). The
    adjustment range is approximative 0…110% of
    Uo nom. For
    output voltages
    Uo > Uo nom, the minimum input voltage ac-
    cording to:
    Electrical Input Data increases proportionally to
    Uo/Uo nom.

    Note: R inputs of n units with paralleled outputs may be
    paralleled, too, but if only one external resistor is to be
    used, its value should be R1/n, or R2/n respectively.
