Helios Series

Established in 1974, Precision Digital Corporation designs, develops, manufactures, sells and distributes digital panel meter devices driven by embedded systems that transform, display and control critical process information. Our products can be located virtually anywhere in the plant; from the control room to Class I Div 1 areas (both explosion-proof and intrinsically safe). They will accept virtually any analog signal such as 4-20 mA, thermocouple, RTD, DC voltage and pulse as well as digital serial data, such as Modbus.


Go with the Helios PD2-6000 when you need a large display meter to display the 4-20 ma output from any transmitter you might have. The PD2-6000 can display that output in six full digits and will also provide the 24 VDC to power the transmitter. The PD2-6000's NEMA 4X enclosure, super bright, 1.8" (46 mm) high LEDs, and wide operating temperature range make it perfect for outdoor applications. The PD2-6000 can also be equipped with a 4-20 mA output as well as four relays that can be used for alarming or control applications, including pump alternation control.

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.

Go with the Helios PD2-6080 when you have multiple, (up to 16), Modbus registers you want to display on a single large display meter. The PD2-6080 can also accept two 4-20 mA signals. The PD2-6080 can be programmed as a Modbus RTU Master, Slave or Snooper allowing it to work in just about any Modbus application. Typically, the upper line displays the PV and the lower line displays the tag.
