DRC Valve Controller

DRC Controllers

The DRC controller drives proportional solenoid valves. The output current is proportional to the command input.

Once configured, the settings are permanently stored in the controller memory.

DRC FEATURES

 Easily configured using HCT Graphical User Interface (GUI) or HCT Hand Held Interface (HHI)

 LED indication of power, output current and fault status

 DIN-rail mount housing with removable terminal blocks

 Multiple modes for single and dual coil applications, programmable enable input

 All input and output limits are independently adjustable

 Adjustable output with short circuit protection, adjustable ramp up and ramp down rates
