These loop-powered 1/8 DIN digital panel meters can be installed virtually anywhere to provide convenient and informative displays of any 4-20 mA signal. One of the most convenient features of these instruments is their dual line display which is typically used to display the process variable on the 5-digit alphanumeric top line and the units or a tag on the 8-digit alphanumeric bottom line. Another common setup is to display the input in one scale on the top line (such as feet) and another scale on the bottom line (such as gallons). Both of these 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 PD6604 that also includes a numeric value of the percentage the bargraph represents.
There is even a model that displays level in feet and inches for customers who prefer to see their levels represented that way rather than in decimal format.
These loop-powered meters can be installed virtually anywhere because they get their power from the 4-20 mA loop and therefore require no separate power source. And they only drop 1.5 V (4.7 V with backlight), so they add very little burden to the loop. Additional features that allow these instruments to be installed virtually anywhere include a NEMA 4X, IP65 front panel, an operating temperature range of -40 to 167°F (-40 to 75°C) (for safe area products), conformally coated PCBs, and a backlit LCD that can be read in bright sunlight or dimly lit areas. Finally, there are intrinsically safe and nonincendive versions of these instruments that can be installed in hazardous areas.
Free, PC-based, software that connects to the meter via a micro USB cable is available for programming and setup of the meters. In addition, the meter can be programmed, setup and operated via the four front panel buttons. Three of these buttons can be used as function keys. In addition, a digital input is standard and is particularly useful for remote reset of the alarms or to trigger an alarm.
All models come equipped with two open collector outputs and are available with two solid state relays and 4-20 mA analog output options. The open collector outputs are useful for alarm indication or pulse output. The relays can be programmed for alarm indication, on/off control, or pump alternation.
Except where noted all specifications apply to operation at +25°C.

Signal Input Conditioning
Non-linear input signals (i.e. weirs & flumes, differential pressure, etc.) can be linearized with the ProVu’s simple to use built-in signal input conditioners, such as square-root extractor, exponential linearizer, horizontal round tank linearizer, or the ProVu’s powerful general purpose 32-point linearizer.
Weir Flow Calculated Using Exponential Math Function
Round Horizontal Tank Math Function
For pump control applications where 2 or more similar pumps are used to control the level of a tank or a well, it is desirable to have the pumps operate alternately; this prevents excessive wear and overheating of one pump over the lack of use of the others. The ProVu can accommodate up to 8 pumps. In the example below, a pair of relays have been set up to alternate every time an on/off pump cycle is completed. Another pair of relays is used for low and high alarms.

Loop Leaders, when ordered with the two solid state relays, have several features that make them ideal for simple duplex pump control. The relays can be programmed to alternate the pumps based on level and runtime thus ensuring even wear on both pumps. If the level remains constant (within on/off points), alternation is based on runtime. If the level cycles the on/off points, alternation is based on level and runtime. If the run time is set to 0, alternation is based on level. The meter also keeps track of runtime for both pumps and the number of times they have cycled.
In addition to the two solid state relays for controlling pumps, the Loop Leaders two open collectors could be used to indicate high or low level alarm conditions.
The Loop Leader can be used as a pump controller to alternate two pumps and provide high and low level alarm indication. The pumps can be programmed to alternate on level and run time and the meter can display the pump run times and the number of times they have cycled. The PD6606–L2N can be used as an intrinsically safe pump controller.
Signal Input Conditioning
The PD6600 Loop Leader process meter allows you to select the signal input conditioner applied to the input: linear, square root, programmable exponent, or round horizontal tank volume calculation.
The programmable exponent function is used to linearize the level signal in open channel flow applications using weirs and flumes and display flow rate in engineering units.
The square root function can be used to linearize the signal from a differential pressure transmitter and display flow rate in engineering units.
The round horizontal tank linearization function automatically calculates the volume in a round horizontal tank with flat ends.
A digital input comes standard on the Loop Leader PD6600 Series. This allows the user to program an external button to activate certain functions immediately like alarm acknowledgement, display minimum/maximum values, tare the display, reset a value, and many more. This allows the Loop Leader to be greatly customized for use in specialized applications. See the PD6600 series manuals for all digital input functions.
Application Timers are used in everyday life; one of the most common examples is the microwave oven. Industrial timers are used in process control applications where certain events or actions need to be controlled by time. Examples include automatic and batch control applications, where the relay needs to be energized for a specific length of time.
The timer fuction is available on the open collector and relay outputs; which means that you can have up to four timers per meter. The start and stop actions can be triggered from the setup menu or by the function keys and digital input. The meter can be setup to display the off/on timer count down.
There are two modes of operation:
Continuous Timer (Interval) At the start of the timer, the output is off and turns on after the Off Delay elapses. The output remains on for the duration of the On Time. The cycle repeats until the user stops the timer either from the menu or a function key.
One-Shot Timer At the start of the timer the output is off and turns on after the Off Delay elapses. The output remains on for the duration of the On Time. The timer stops and the cycle does not repeat.
A sensor detects the bottle is in place and triggers the digital input to start the timer
The timer output controls the filling pump
The On Time is set according to the time needed to fill the bottle
The connectors’ label, affixed to the meter, shows the location of all connectors available with requested configuration.
Current Loop (4-20 mA) Connections
The following figures show a 4-20 mA current loop connected to the meter. The first figure shows the connection with the backlight disabled and the second shows the connection with the backlight enabled. The meter is powered by the 4-20 mA current loop.
Digital Input Connection
A digital input is standard on the meter. This digital input is connected with a normally open contact across DI+ and DI-, or with an active low signal applied to DI+.
4-20 mA Output Connections
Connections for the 4-20 mA transmitter output are made to the connector terminals labeled MA OUT. The 4-20 mA output must be powered from an external power supply.
Relay connections are made to two four-terminal connectors. Each relay’s C terminal is common only to the normally open (NO) contact of the corresponding relay.
Open Collector Outputs
Open collector output 1 and 2 connections are made to terminals labeled O1+ and O1-, and O2+ and O2-. Connect the alarm or pulse input device as shown below.
