The Schneider Electric ACE969 family includes several variants, each optimised for different communication requirements and application scenarios. Understanding the differences between models helps engineers make the best selection decisions at the project design stage, avoiding system integration issues caused by incompatible module choices.
The ACE969 TP2 (ACE969TP-2) is the dual-protocol (Modbus + DNP3) representative of the family, offering strong protocol compatibility — ideal for applications that need to interface with different SCADA platforms.
ACE969 Family Model Comparison
- ACE969TP-2: RS485, Modbus RTU and DNP3, for Sepam series 20/40/60/80
- ACE969-2: RS485 multi-protocol, supports IEC 60870-5-103 and other protocols
- ACE969FO: Fibre-optic version, suited for long distances or high-interference environments
- ACE949-2: RS485, Modbus communication for the Sepam series 10
Recommended Scenarios for ACE969 TP2
- New substations or distribution rooms requiring Modbus SCADA integration
- Retrofit projects where the existing system uses DNP3 protocol
- Industrial switchgear panels fitted with Sepam series 20/40/60/80 relays
- Compact designs requiring DIN rail mounting
"Selecting the correct ACE969 family variant is the critical first step in successfully integrating Sepam protection relays with your automation system."
When selecting a model, engineers should simultaneously consider the specific Sepam relay type (S20/S40/S60/S80) and the protocols supported by the upstream SCADA system, to confirm that the chosen ACE969 communication interface is fully compatible with the overall system architecture.
