DESCRIPTION
The DIS471 provides a display proportional to a DC input signal. The unit
includes filtering and conditioning to reduce susceptibility to transients and
noisy operations. The digital display utilizes an auto-zero dual-slope
integrating A/D converter for accuracy and stability.
All DIS instruments are gasketed and, when properly installed, are NEMA-4X
waterproof and corrosion resistant. ZERO and SPAN controls are accessible by
removing a gasketed front access panel. The display controls are wide-ranging so
that it can be calibrated to display engineering units. Decimal point selection
is made with a switch, accessible from the rear.
A complete set of engineering unit labels is sent with each DIS.
Terminations are made to a screw terminal connector on the rear of the case.
TYPICAL APPLICATIONS
DC voltage, current and process indication.
MOUNTING
The DIS471 is designed to be mounted from the front panel through a standard
horizontal 3.62 X 1.77 inches (1/8 DIN) cutout. Two mounting cam-screws allow
the securing of the DIS471 to the panel from the front.
