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.
