Compatible Replacement & Equivalent Models
When the IMHSS03 is unavailable or end-of-life, the following models may serve as functional replacements depending on system configuration. Always verify firmware and backplane compatibility before substitution.
- ABB IMHSS04 – Next-generation hydraulic servo module; direct functional upgrade with enhanced diagnostics
- ABB IMHSS01 / IMHSS02 – Earlier revisions; compatible in legacy AC800M racks with firmware constraints
- ABB PM866K01 + Servo I/O Expansion – Alternative architecture using a CPU module with dedicated servo I/O for new projects
- Third-party servo controllers (Moog, Bosch Rexroth) – Require custom integration; not plug-and-play replacements
Note: Konmask.com recommends consulting ABB’s compatibility matrix or contacting our technical team before substituting any servo module in a live system.

- Backplane: AC800M S800 I/O bus and TB820 ModuleBus
- Not compatible with: ABB Freelance DCS, Symphony Plus, or non-ABB DCS platforms without custom gateway
Selection Guide
Use the following criteria to determine whether the IMHSS03 is the right module for your application:
- Existing AC800M system? → IMHSS03 is the native, lowest-risk choice.
- Need enhanced diagnostics or PROFINET? → Evaluate IMHSS04 as an upgrade.
- Legacy system with IMHSS01/02? → IMHSS03 is a compatible upgrade; verify firmware version.
- Greenfield project? → Consider PM866 + modern servo I/O for longer lifecycle support.
- Budget-constrained retrofit? → Contact Konmask.com for certified refurbished IMHSS03 availability.

Replacement & Compatibility FAQ
Q: Can I replace IMHSS03 with IMHSS04 without reprogramming?
A: In most cases yes, but a Control Builder M project update is recommended to leverage IMHSS04’s new features and ensure parameter mapping is correct.
Q: Is IMHSS03 still in production?
A: ABB has transitioned to newer servo modules. IMHSS03 is available as a spare part. Contact Konmask.com for current stock status.
Q: Can IMHSS03 work with non-ABB hydraulic valves?
A: Yes, provided the valve accepts a standard ±10 V or 4–20 mA command signal. Custom scaling is configurable in CBM.
Q: What is the warranty on Konmask-supplied IMHSS03 units?
A: 12 months from date of shipment. See our warranty policy for full terms.
