• The Loop Leader PD6620 is an ATEX and IECEx approved, UL listed, intrinsically safe and nonincendive, loop-powered, 1/8 DIN flow rate/totalizer designed for demanding process control applications. A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, loop-powered backlight with a unique red backlight option for alarm conditions, and optional bargraph display (PD6628) provide a clear and attractive presentation of the process. All models come equipped with two open collector outputs and are available with two solid state relays and a 4-20 mA analog output. These outputs can be programmed for alarm indication, signal retransmission via pulse or analog signal, pump control, and a number of other useful features. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines; the meter gets all of the power it needs from the 4-20 mA loop. The Loop Leader loop-powered rate/totalizer is built in a shallow-depth case with a IP65 front and features loop-powered backlighting and a wide -40 to 158°F (-40 to 70°C) operating temperature range. It doesn't matter if it's in hazardous areas, indoors or outdoors, in bright sunlight or a dimly lit plant, or in an area that is wet, dirty, hot, or cold, the Loop Leader can go just about anywhere.
