+15 V 15 VDC Power Source for active
(3-wire) input devices connected to
the Universal IN
n terminals;
provides 80 mA total current.
Note: 80mA current limit is shared
between the BI + 15V supply and the
UI + 15V supply.
Same as Binary INn
Note: Use 3-wire cable for devices
that source power from the +15V
terminal.
COM 15 VDC Power Source for active
(3-wire) input devices connected to
the Universal IN
n terminals;
provides 80 mA total current.
Note: 80mA current limit is shared
between the BI + 15V supply and the
UI + 15V supply.
Same as Binary INn
