PD2-6060 Helios Dual Analog Input Process Meter

Brand: Precision Digital Corporation

Go with the Helios PD2-6060 when you need a large display meter to display two 4-20 mA inputs on one meter. 

Both of these inputs can be displayed on six full digits and each transmitter is provided with its own 24 Vdc transmitter power supply. 

The PD2-6060 can also perform a variety of math functions on those two inputs, such as computing the difference between them or summing them together.
  • Dual-input process meter with math functions
