Description
Model PI 800 is
a 4½ digit (±19,999
count) industrial process indicator with large,
bright, 2¼" (57 mm) tall LED digits legible at
up to 75 feet (23 m). It is designed to read out
directly in engineering units, such as PSI, GPM
or degrees, from a voltage signal such as 0-1V,
1-5 V, 0-10V or 1-10V. Scaling adjustments and
decimal point selection are accessible from the
front by removing an access plug.
The sealed
surface-mount case provides protection for
installation in dirty or damp environments.
Three mounting methods are provided for:
thru-panel mounting, raised surface mounting, or
flush surface mounting. Electrical connections
are via screw terminals. Please see our
Mechanical Section. Standard power is 115 Vac.
Options include
230 Vac power, an excitation output adjustable
from 1.3 to 24 Vdc to drive transducers, an
analog output of 1 mV count to drive recording
devices, and a NEMA-4 enclosure.
A Two-Year
Warranty is standard.
