Communication performance is tailored for industrial reliability. The module implements the EIA 2-wire RS485 differential standard, which provides superior noise immunity compared to single-ended RS232 by rejecting common-mode interference induced by nearby power cables, variable frequency drives, and switching equipment. The Modbus RTU protocol is supported natively, with Sepam relays operating as slave stations on the network—responding to polling requests from a Modbus master (typically a SCADA system, PLC, or PowerLogic gateway) with real-time measurements, protection status, event logs, and diagnostic data. The link activity LED on the module's front panel flashes whenever the Sepam relay is actively transmitting or receiving data, providing technicians with instant visual feedback during commissioning, troubleshooting, or routine maintenance checks.

FAQs
-
What is the difference between ACE949 and ACE949-2?
+The difference lies in the distributed power supply level transmitted over each Sepam in parallel with the RS-485 Modbus line. The ACE949-2 specifically handles 2-wire RS-485 communication -
What is the core function of the ACE949-2?
+It bridges a Sepam protection relay with an electrical EIA 2-wire RS485 differential communication network using Modbus RTU protocol. -
Can the ACE949-2 act as an autonomous Modbus RS485 to Modbus TCP/IP gateway?
+No, the module cannot operate as a standalone protocol converter without being connected to a Sepam host relay. -
What type of network cable connects the relay to the module?
+The remote interface connects to the Sepam base unit via a prefabricated CCA612 cable (length 3 meters).
