Application-Specific FAQ
Q: Is the VT5035-17 compatible with my existing Rexroth proportional valve without rewiring?
A: In most cases, yes. The VT5035-17 is designed as a plug-compatible replacement within the VT5035 series. However, always verify the solenoid coil resistance and command signal type against your existing wiring before installation.
Q: Can this card be used with non-Rexroth proportional valves?
A: The VT5035-17 is optimized for Rexroth solenoid specifications. Use with third-party valves is possible if the solenoid coil impedance and current requirements fall within the card’s output range, but is not officially supported by Rexroth.
Q: What is the difference between VT5035-17 and VT5035-1X?
A: The suffix (e.g., /1X, /2X, /17) typically denotes the design series or hardware revision. The /17 suffix indicates a specific revision with defined feature set. Contact Konmask to confirm cross-compatibility with your application.
Q: Do you supply the full Rexroth VT5035 series?
A: Yes. Konmask stocks and sources multiple variants across the VT5035 amplifier card family. Contact us with your specific part number for availability.
Q: Can Konmask provide technical support for commissioning?
A: Yes. Our engineering support team can assist with wiring diagrams, parameter setup, and troubleshooting via email or video call.
