1 AIR PRESSURE STABILIZATION VENT (57.15) 2.25 X Z Y 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 dual 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/IP65 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 dual Form C relay output and RS232 or RS485 serial communications. The outputs can activate based on either counter or rate setpoint values. An internal batch counter can be used to count setpoint output activations. 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. Do not use this unit to directly command motors, valves, or other actuators not equipped with safeguards. To do so can be potentially harmful to persons or equipment in the event of a fault to 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. SPECIFICATIONS 1. DISPLAY: 2.25" (57 mm) or 4" (101 mm) intensity adjustable Red LED 2. POWER REQUIREMENTS: AC POWER: 50 to 250 VAC 50/60 Hz, 26 VA DC POWER: 21.6 to 250 VDC, 11 W DC OUT: +24 VDC @ 100 mA if input voltage is greater than 50 VAC/VDC +24 VDC @ 50 mA if input voltage is less than 50 VDC Isolation: 2300 VRMS for 1 min. to all inputs and outputs 3. COUNT INPUT(S): Counter(s) have DIP switch selectable pull-up (7.8 KƒÇ) or pull-down resistors (3.9 KƒÇ) that determine active high or active low input logic. Counters are DIP switch selectable for high or low frequency (Damping capacitor provided for switch contact bounce. Limits input frequency to 50 Hz and input pulse widths to 10 msec min.)
