OMEGA’s DP20 series new universal panel meter delivers high performance in a 1/8 DIN size for panel mount, and integration in a wide range of applications. The DP20 accepts universal inputs, including thermocouple, RTD, process (mA & Vdc), resistance, and true RMS voltage and current. By configuration, it will work as an AC and DC voltmeter (up to 600 V) and AC and DC ammeter (up to 5 A) offering application flexibility for process control and industrial requirements. A single universal power supply allows this unit to be suited for global use.
Introduce Omega DP20 Series
The optional relays, analog output, and Modbus® RTU serial communications provide customization, control and communication capability. Additional features of the economical DP20 panel meter include scaling, NEMA 4 (IP65) protection, and programmable decimal points.

Nice meter for the priceMy application was to display rpm on a mill, where the speed control produced a 0-10v signal that corresponded to 0-4500 rpm. The DP20 was easy to program for that use and works well. Be aware the case is very thin, and the clamps are plastic so it's not as robust as you might be used to.

Does the job but ...I may be a bit dense about these things, but I found the nested menu/push button configuration complicated. In the end I got the scaling and alarms set up as I needed, but I'm not sure I could explain how I did this. But, in the end it works well as advertised.

Update - Failed after three monthsThis is an update to my review from a few months ago. It worked fine for a short time, then the display went dead. I pulled it out and tried it on the bench, but no dice. Unfortunately, I had to modify the case to install it so it's not returnable. I'm going to try another one, and hope this was just a bad one.
I can't seem to figure out how to scale the signal to have numbers AFTER the decimal point. I am using an externally powered PX119 set up for 4-20mA. I am measuring psi from 0-30, and I would like the display to read 9.45 psi rather than just 9 or .09 etc
Asked by: AdamB
Dear AdamB, thank you for contacting Omega Engineering. For scaling the DP20 to read from 0.00 through 30.00 psi, assuming you have the wiring and the internal jumpers correct, keep pressing the little square button, till you see "SCAL" , you will see DP (Decimal Point) : Set the decimal point in the middle, so XX.XX . Your D.Lo should be 00.00 and D.Hi should be 30.00. You should then be reading from 00.00 to 30.00.
