System Compatibility
The VT-3014 S35 R5 is designed for use within the Rexroth VT-3000 amplifier card rack system and is compatible with the following valve families:
- Rexroth 4WRPH / 4WRKE proportional directional control valves
- Rexroth DBEM / DREM proportional pressure control valves
- Rexroth 2FRE / 2FRM proportional flow control valves
- PLC systems with ±10 V analog output (Siemens S7, Allen-Bradley, Mitsubishi Q/iQ-R series)
- DCS platforms with standard 4–20 mA or ±10 V command signals (via signal converter)
Selection Guide
Use the following criteria to confirm the VT-3014 S35 R5 is the correct card for your application:
- Step 1 – Valve Type: Confirm your proportional valve requires a dual-solenoid amplifier (VT-3014 series). Single-solenoid valves use VT-3013.
- Step 2 – Revision Level: Check the “S35” suffix — this denotes the hardware revision. Mixing revisions in the same rack is generally safe but verify with Rexroth documentation.
- Step 3 – Software Version: “R5” indicates firmware/parameter set version. Confirm compatibility with your existing rack controller firmware.
- Step 4 – Supply Voltage: Verify your rack provides stable 24 V DC ±15% to the card slot.
- Step 5 – Command Signal: Confirm your PLC/DCS outputs ±10 V differential or 0–10 V single-ended command signal.
- Step 6 – Quantity & Lead Time: Contact Konmask.com for stock availability and expedited sourcing options.

Replacement & Compatibility FAQ
Q: Can VT-3014 S36 R5 replace VT-3014 S35 R5 directly?
A: In most cases yes — S36 is a hardware revision update and is pin-compatible. However, verify parameter settings as some default values may differ.
Q: Is the VT-3014 S35 R5 compatible with Siemens S7-300/400 PLC analog outputs?
A: Yes. The ±10 V command input is standard and directly compatible with Siemens SM331/SM332 analog I/O modules.
Q: Can I use a third-party amplifier card as a replacement?
A: Functionally possible with wiring adaptation, but we recommend OEM replacement to avoid re-commissioning costs and warranty issues.
Q: Do you supply refurbished units?
A: Yes. All refurbished units undergo full functional testing and are clearly labeled. New OEM units are also available — specify your preference when ordering.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–4 week lead time depending on sourcing channel.
