CAPV-H-4-20MA-x: Connector Amplifier For Proportional Valves

The 4-20mA Connector Amplifier simplifies control of proportional solenoids by supplying a current proportional to an input control (4-20mA). It accepts 12VDC or 24VDC power supply voltage. This linear solenoid driver utilizes high frequency switching output (PWM) to provide a DC current output. The options for maximum current output include 2 A, 1.2 A or 600mA. A current sensing circuit maintains output current regardless of changes in input voltage and coil resistance. The user can adjust maximum and minimum current. Ramp time, dither frequency and amplitude can also be adjusted to match the application. The unit is available with a DIN 43650 connection to mount directly on the coil. It is also available with 0-10V or 0-5V inputs. A remote mount version is housed in a rugged metal box.

Applications


  • 12VDC or 24VDC supply voltage
  • Current sensing circuit maintains output regardless of changes in input voltage and coil resistance
  • Modern technology utilizing high frequency switching output (PWM)
  • Energy efficient design (no heat sink is required)
