Compatible Replacement & Equivalent Models
When the K-AO01 is unavailable or end-of-life, the following models may serve as functional equivalents depending on your system configuration. Always verify backplane compatibility and firmware version before substitution.
- Hollysys K-AO02 – Extended channel variant within the same HOLLiAS-K series; verify channel count and signal range
- Hollysys FM148 – HOLLiAS-M series AO module; requires system migration if switching DCS platforms
- Siemens 6ES7135-4GB01-0AB0 – ET 200S analog output module; suitable for cross-brand migration projects with engineering adaptation
- ABB AI810 / AO810 – S800 I/O series; compatible in multi-vendor DCS environments with appropriate marshalling
- Yokogawa AAI141-S00 – CENTUM VP analog output; for cross-platform replacement with full re-engineering
Note: Cross-brand replacements require engineering assessment. Contact Konmask for sourcing and compatibility verification.
Why Choose the Original Hollysys K-AO01
- Native HOLLiAS-K compatibility: Plug-and-play with existing K-series backplanes and controllers — no firmware modification required
- Proven reliability: Widely deployed in Chinese petrochemical and power plants with documented long-term stability
- Regulatory compliance: Meets GB/T and IEC 61131 standards for industrial control systems
- Simplified maintenance: Hot-swap capable; minimizes downtime during module replacement
- OEM support: Hollysys provides lifecycle support, spare parts, and firmware updates for HOLLiAS-K platforms
Typical Applications
- Petrochemical refinery process control (flow, pressure, temperature setpoint output)
- Power plant boiler and turbine control loops
- Municipal water treatment and wastewater management systems
- Pharmaceutical batch process automation
- Steel and metallurgy continuous process lines
- Building automation and HVAC control integration
System Compatibility
The K-AO01 is designed exclusively for the Hollysys HOLLiAS-K DCS platform. Confirm compatibility with the following system components before ordering:
- Controller: HOLLiAS-K series main controller (K-CU01, K-CU02, or equivalent)
- Backplane: K-series I/O backplane (8-slot or 16-slot)
- Engineering Software: HOLLiAS-K configuration software (version compatibility must be verified)
- Power Module: K-PS01 or equivalent 24 VDC power supply module
This module is not compatible with HOLLiAS-M, HOLLiAS-A, or third-party DCS backplanes without hardware and software adaptation.
Selection Guide
Use the following criteria to confirm the K-AO01 is the right module for your application:
- Step 1 – Confirm DCS platform: Verify your system is HOLLiAS-K series. Check the controller model label.
- Step 2 – Determine output type: K-AO01 supports 4–20 mA and 0–10 V. Confirm your field instruments accept these signal types.
- Step 3 – Count required channels: K-AO01 provides 8 AO channels. For higher channel density, evaluate K-AO02.
- Step 4 – Check slot availability: Confirm available I/O slots on your backplane before ordering.
- Step 5 – Verify firmware version: Ensure your DCS engineering software version supports the K-AO01 module firmware.

Replacement & Compatibility FAQ
Q: Can I replace K-AO01 with K-AO02 directly?
A: K-AO02 is a close variant but may have different channel counts or signal ranges. Verify the datasheet and test in a non-production slot first.
Q: Is K-AO01 compatible with HOLLiAS-M systems?
A: No. HOLLiAS-M uses a different backplane and bus architecture. A direct swap is not possible without system redesign.
Q: Can I use a Siemens or ABB AO module as a drop-in replacement?
A: Not directly. Cross-brand replacements require marshalling panel redesign, signal conditioning, and software reconfiguration. Konmask can assist with migration planning.
Q: Do you supply refurbished K-AO01 units?
A: Yes. Refurbished units are clearly labeled, tested, and covered by our 90-day warranty. Contact us for pricing.
Q: How do I confirm the module is genuine Hollysys?
A: Genuine units carry Hollysys holographic labels and serial numbers traceable to Hollysys production records. We provide documentation on request.
