Carlo Gavazzi WM12-96.AV5.3.3.S End-of-Life Information
Key Conclusion: This model together with the entire WM12 series was officially discontinued in April 2020. The official replacement is the WM15 series, while the WM14 series can be used as a temporary transitional replacement.
- Official EOL Basis
Carlo Gavazzi officially released an announcement in April 2020:
“With the launch of the new WM15, the WM12, WM14, and EM26 are discontinued.”
As a 96×96mm panel-mounted three-phase multifunction power indicator in the WM12 series, WM12-96.AV5.3.3.S is included in this full-series discontinuation.
- EOL Timeline & Replacement Arrangement
| Time Node | Event | Observaciones |
| Apr-20 | WM15 series launched; WM12 series officially discontinued | Official EOL (End of Life) Fecha |
| Before Discontinuation | WM14 series as upgraded replacement for WM12 | WM14-96AV533S is direct drop-in replacement for WM12-96.AV5.3.3.S |
| After April 2020 | WM15 series becomes final successor to WM12/WM14 | Higher accuracy (Clase 1 kWh) and added functions such as harmonic analysis |
- Key Information of Replacement Products
- Direct Drop-in Replacement:
WM14-96AV533S (WM14-96×96 400/660V 5AAC 18-60VDC SERIAL)
Identical 96×96mm panel size and mounting method
Same AV5 range: 380/660V L-L / 5(6)A AC
Same 18-60VDC power supply and RS485 communication
- Final Upgraded Replacement: WM15 Series
Accuracy upgraded to Class 1 para energía activa
Added harmonic distortion measurement
Supports single/two/three-phase and wild-leg systems
Optional pulse output, Modbus RTU or M-Bus communication
- Adquisitivo & Recomendaciones de mantenimiento
- Stock Status: Only limited second-hand or surplus stock available; brand new original units are nearly out of stock.
- Maintenance Support: Carlo Gavazzi generally provides 6 years of spare parts support for discontinued models.
- Model Migration: New projects are recommended to adopt the WM15 series directly; existing projects can use the WM14 series for transitional upgrading.
Replacement Analysis of WM12-96.AV5.3.3.S and WM12-96.AV5.3.3.X
Conclusión central: The two models are physically and hardware compatible and can be directly interchanged for installation; however, there is a key difference in communication functions. Their interchangeability depends on whether the system requires RS485 communication.
- Core Difference Comparison (Only One Distinction)
| Modelo | Diferencia clave | Functional Impact | Application Limitation |
| WM12-96.AV5.3.3.S | With RS485 serial communication (S=Serial) | Supports communication with host computer/PLC via Modbus RTU protocol for remote monitoring and data acquisition | Suitable for automation systems requiring centralized monitoring |
| WM12-96.AV5.3.3.X | Without RS485 communication (X=No Serial) | Only local LED display available; remote data reading not supported | Suitable for simple applications requiring only on-site parameter viewing |
All other parameters are completely identical:
modelo básico: WM12-96 (96×96mm panel mounting, with built-in programming keypad)
Range code: AV5 (380/660V L-L / 5(6)A AC)
System type: 3 (1/2/3-phase system, unbalanced load)
Power supply type: 3 (18-60VDC power supply)
Identical measurement accuracy, electrical specifications, physical dimensions and ingress protection rating
- Interchangeability Feasibility Judgment
2.1 ✅ Applicable Interchange Scenarios (Bidirectional)
System does not require RS485 communication: The X model can directly replace the S model, saving cost while fully meeting on-site display requirements.
Temporary replacement only: Either model can be used as a temporary spare part for fault maintenance without affecting basic measurement and display functions.
New project design: Selection based on actual communication demand; hardware mounting dimensions and wiring are fully compatible.
2.2 ❌ Non-interchangeable Scenarios (Unidirectional Restriction)
| Modelo Original | Target Model | Reason for Non-interchangeability | Solución |
| S (With Communication) | incógnita (Without Communication) | The system relies on RS485 remote monitoring; communication will be interrupted after replacement | Keep S model, or upgrade to communication-enabled WM15 series |
| incógnita (Without Communication) | S (With Communication) | No communication wiring or host interface in the system; the communication function cannot be used | No need for replacement, or upgrade after completing communication infrastructure |
- Key Points for Replacement Operation
3.1 Instalación física
Exactly the same 96×96mm panel cutout size, direct plug-and-play replacement.
Consistent terminal definition; no modification required for main circuit and power wiring.
Same ingress protection level (Front IP65, Terminal IP20) with consistent environmental adaptability.
3.2 Function Configuration
The built-in programming keypad operates identically; original parameter settings can be copied directly.
Fully compatible in measurement parameters, display modes and alarm threshold configuration.
When replacing X with S, additional configuration of RS485 address (1-255) and communication parameters (9600bps, 8N1) se requiere.
3.3 Discontinuation & Recomendación de reemplazo
Both models were officially discontinued in April 2020 together with the entire WM12 series.
Official final replacement: WM15 Series (Clase 1 mayor precisión, with additional harmonic analysis function).
Transitional replacement: WM14-96AV533S / WM14-96AV533X (retains the same panel size and functions).
- Selección & Decision Summary
Communication demand is the key; S with comm, X without. Physically interchangeable, only reliable with function matching.
Replacement Decision Tree
- Is RS485 communication required?
Sí: Must choose S version or upgrade to communication-capable WM15 model
No: Both S and X are acceptable; X is more cost-effective
- Does the system have existing communication infrastructure?
Sí: Prioritize S version to make full use of existing resources
No: Choose X version to avoid redundant functions
