  • Simplifies commissioning and troubleshooting in hydraulic systems with servo and proportional valves
  • All standard servo- and proportional valves with 6+PE connectors are supported (MOOG, Parker-Hannifin, Bosch-Rexroth, Eaton, and many others)
  • Additional control for ON/OFF pilot valve
  • Intuitively simple and comfortable interface
  • Extremely bright OLED display and LED indicators for comfortable operating at any light conditions
  • Supports external and internal operation modes
  • Advanced set of control modes: -10V… +10V, -2V… +2V, 0V… +10V, -10mA… +10mA, -2mA… +2mA, 0mA… +10mA, 4mA… 20mA, 10mA… 14mA, -20mA… +20mA
  • The device keeps the last settings after switching power off
  • Supports current and voltage feedback signals
  • Allows to monitor voltage of the power supply and enable signals
  • Enable output includes the current limiter for safe operation
  • Fast access to any item of the control menu
  • The service case comprises a test device as well as an optional power supply unit (+24V, 3.75A) and connecting cables
  • Reverse polarity, overload, and short circuit protections
  • Compact and robust construction
  • Completely sealed enclosure
  • High reliable keyboard
  • Robust waterproof case
