GENERAL DESCRIPTION
The Large Display is a versatile display available as a DC volt, current, or
process meter with scaling, serial communications and dual relay outputs. The 5
digit displays are available in either 2.25" or 4" high red LED digits with
adjustable display intensities. The 2.25" high models are readable up to 130 feet.
The 4" high models are readable up to 180 feet. Both versions are constructed
of a NEMA 4X/IP65 enclosure in light weight aluminum.
All models also come with dual Form C relay outputs and RS232 / RS485
serial communications.
SAFETY SUMMARY
All safety regulations, local codes and instructions that appear in this and
corresponding literature, or on equipment, must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment connected to
it. If equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
The protective conductor terminal is bonded to conductive
parts of the equipment for safety purposes and must be
connected to an external protective earthing system.
