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 in or 4 in high red LED digits with adjustable display intensities. The 2.25 in high models are readable up to 130 feet. The 4 in 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 anticoincidence 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.
