GENERAL DESCRIPTION

The Large Display is a versatile display that can be configured as a single or
dual counter with rate indication, scaling, serial communications and a relay
output. There are also basic models that have a single counter with direction
control only (no scaling or relay output).
The 4 & 6 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. All versions are constructed
of a NEMA 4X enclosure in light weight aluminum.
The 6-digit programmable models have two signal inputs and a choice of
eight different count modes. These include bi-directional, quadrature and anti-
coincidence counting, as well as a dual counter mode. When programmed as a
dual counter, each counter has separate scaling and decimal point selection.
Rate indication is available on the programmable models only. The rate
indicator has separate scaling and decimal point selection, along with
programmable display update times. The meter display can be toggled either
manually or automatically between the count and rate values.
The programmable models also come with a Form C relay output and jumper
selectable RS232 or RS485 serial communications.

SAFETY SUMMARY
