PD6620 Loop Leader Loop-Powered Rate/Totalizer
Brand: Precision Digital Corporation
These loop-powered 1/8 DIN flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of flow rate and total from a 4-20 mA signal.
One of the most convenient features of these instruments is their ability to display both flow rate and total at the same time. For instance, flow rate is typically displayed on the 5-digit alphanumeric top display and flow total or grand total on the 8-digit alphanumeric bottom display. Both display lines use 14-segment, alphanumeric characters for clear indication of tags, units, or alarm messages.
Further enhancing the display on these instruments is a 20-segment bargraph available on the PD6624/8 that also includes a numeric value of the percentage the bargraph represents.
Free, PC-based, MeterView XL software that connects to the meter via a micro USB cable is available for programming and setup of the meters.
All models come equipped with two open collector outputs and a digital input. There are also models available with two solid-state relays and isolated 4-20 mA analog output options.
The open collector outputs are useful for alarm indication. The digital input can be used to reset the total, acknowledge the relays, to start/stop a timer/stopwatch, and more. The relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.
