HR-LCD 4-20 scaled/unscaled
HR-LCD 4-20 SCALED/UNSCALED
The HR-LCD 4-20 scaled/unscaled is a permanently sealed, electronic LCD register that produces a scaled/unscaled output as
well as an analog 4-20 mA DC output signal with a dual output wire design .
Refer to
Wire Connections
• Scaled/unscaled side cable (
Flying lead for field splice connection)
◊ For a scaled output, connect the
red
wire (positive) and the
black
wire (negative) .
◊ For an unscaled output, connect the
green
wire (positive) and the
black
wire (negative) .
OTE:
N
The unscaled output will be active only when the device is powered by the 4-20 output .
• 4-20 mA side cable (
Flying lead for field splice connection)
