Carlo Gavazzi WM12-96.AV5.3.3.S End-of-Life Information

Wichtigste Schlussfolgerung: 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.

1. 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.

3. Key Information of Replacement Products
4. 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)Und AC

Same 18-60VDC power supply and RS485 communication

2. Final Upgraded Replacement: WM15-Serie

Accuracy upgraded to Class 1 für aktive Energie

Added harmonic distortion measurement

Supports single/two/three-phase and wild-leg systems

Optional pulse output, Modbus RTU or M-Bus communication

4. Einkauf & Wartungsempfehlungen
5. Stock Status: Only limited second-hand or surplus stock available; brand new original units are nearly out of stock.
6. Maintenance Support: Carlo Gavazzi generally provides 6 years of spare parts support for discontinued models.
7. 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

Core Conclusion: The two models are physically and hardware compatible and can be directly interchanged for installation; Jedoch, there is a key difference in communication functions. Their interchangeability depends on whether the system requires RS485 communication.

1. Core Difference Comparison (Only One Distinction)

All other parameters are completely identical:

Basismodell: WM12-96 (96×96mm panel mounting, with built-in programming keypad)

Range code: AV5 (380/660V L-L / 5(6)Und 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

2. 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.

Neues Projektdesign: Selection based on actual communication demand; hardware mounting dimensions and wiring are fully compatible.

2.2 ❌ Non-interchangeable Scenarios (Unidirectional Restriction)

3. Key Points for Replacement Operation

3.1 Physische Installation

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 (Vorne 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) ist erforderlich.

3.3 Einstellung & Ersatzempfehlung

Both models were officially discontinued in April 2020 together with the entire WM12 series.

Official final replacement: WM15-Serie (Klasse 1 höhere Genauigkeit, with additional harmonic analysis function).

Transitional replacement: WM14-96AV533S / WM14-96AV533X (retains the same panel size and functions).

4. Auswahl & Decision Summary

Communication demand is the key; S with comm, X without. Physically interchangeable, only reliable with function matching.

Replacement Decision Tree

1. Is RS485 communication required?

Ja: Must choose S version or upgrade to communication-capable WM15 model

NEIN: Both S and X are acceptable; X is more cost-effective

2. Does the system have existing communication infrastructure?

Ja: Prioritize S version to make full use of existing resources

NEIN: Choose X version to avoid redundant functions
