1AIR PRESSURE STABILIZATION VENT (57.15)2.25XZYGENERAL DESCRIPTIONThe Large Display is a versatile display that can be configured as a single ordual counter with rate indication, scaling, serial communications and a dualrelay output. There are also basic models that have a single counter withdirection control only (no scaling or relay output).The 4 & 6 digit displays are available in either 2.25" or 4" high red LED digitswith adjustable display intensities. The 2.25" high models are readable up to 130feet. The 4" high models are readable up to 180 feet. All versions are constructedof a NEMA 4X/IP65 enclosure in light weight aluminum.The 6-digit programmable models have two signal inputs and a choice ofeight different count modes. These include bi-directional, quadrature and anti-coincidence counting, as well as a dual counter mode. When programmed as adual counter, each counter has separate scaling and decimal point selection.Rate indication is available on the programmable models only. The rateindicator has separate scaling and decimal point selection, along withprogrammable display update times. The meter display can be toggled eithermanually or automatically between the count and rate values.The programmable models also come with a dual Form C relay output andRS232 or RS485 serial communications. The outputs can activate based oneither counter or rate setpoint values. An internal batch counter can be used tocount setpoint output activations.SAFETY SUMMARYAll safety regulations, local codes and instructions that appear in this andcorresponding literature, or on equipment, must be observed to ensure personalsafety and to prevent damage to either the instrument or equipment connected toit. If equipment is used in a manner not specified by the manufacturer, theprotection provided by the equipment may be impaired.Do not use this unit to directly command motors, valves, or other actuatorsnot equipped with safeguards. To do so can be potentially harmful to persons orequipment in the event of a fault to the unit.The protective conductor terminal is bonded to conductiveparts of the equipment for safety purposes and must beconnected to an external protective earthing system.SPECIFICATIONS1. DISPLAY: 2.25" (57 mm) or 4" (101 mm) intensity adjustable Red LED2. POWER REQUIREMENTS:AC POWER: 50 to 250 VAC 50/60 Hz, 26 VADC POWER: 21.6 to 250 VDC, 11 WDC 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 VDCIsolation: 2300 VRMS for 1 min. to all inputs and outputs3. COUNT INPUT(S):Counter(s) have DIP switch selectable pull-up (7.8 K) or pull-downresistors (3.9 K) that determine active high or active low input logic.Counters are DIP switch selectable for high or low frequency (Dampingcapacitor provided for switch contact bounce. Limits input frequency to 50Hz and input pulse widths to 10 msec min.)Input A Trigger levels: VIL = 1.25 V max; VIH = 2.75 V min; VMAX = 28 VDCInput B Trigger levels: VIL = 1.0 V max; VIH = 2.4 V min; VMAX = 28 VDCOverflow Indication: Display “” alternates with overflowed count value.LD200400, LD200600, LD400400, & LD400600:Count Rate: 25 KHz max. @ 50% duty cycle (no scaling)LD2006P0 & LD4006P0:Maximum Count Rates: 50% duty cycle, count mode dependent.With setpoints disabled: 25 KHz, all modes except Quadrature x4 (23 KHz).With setpoint(s) enabled: 20 KHz, all modes except Dual Counter (14KHz), Quadrature x2 (13 KHz) and Quadrature x4 (12 KHz).4.
