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.
