Series DHII Digihelic Differential Pressure Controller
Does not ship to VA, United States
Description
The Series DHII takes all the fabulous features of the standard Digihelic Pressure Controller and packages them in a robust NEMA 4 (IP66) housing.
The Digihelic II Pressure Controller combines the 2 SPDT control relays, 4-20 mA process output and Modbus communications with a large, brightly backlit 4 digit LCD display that can easily be seen from long distances.
The electrical wiring has also been enhanced in the DHII with its detachable terminal blocks. The removable terminals allow the install to easily wire the terminal block outside the housing and then attach to the circuit board, reducing wiring difficulties and installation time on the process.
The Digihelic II Differential Pressure Control in the new NEMA 4 (IP66) enclosure enables this product to be the perfect choice when mounting pressure controls outdoors in such applications as rooftop air handlers.
This housing also makes it the ideal solution for surface mounting in clean rooms or facilities where water or a cleaning solution is utilized in maintaining plant cleanliness.
Features- NEMA 4 housing enables a range of uses both outdoors or indoors where water is present
- Large backlight LCD display provides local reading from a distance
- Detachable terminal blocks reduce wiring difficulties saving installation time
