Product Description

The ACE919CA is an RS485/RS485 converter interface module. Its primary function is to connect a master computer (or a central monitoring system) equipped with an RS485 serial port to a 2-wire RS485 network of stations (such as Sepam relays). It handles network polarization and impedance matching automatically.

Product Parameters

Product Advantages

• Plug-and-Play Matching: Automatically performs network polarization and impedance matching without requiring manual flow control signals.
• Integrated Power Supply: It doesn’t just convert signals; it also provides the distributed DC power required by other interfaces like the ACE949-2, ACE959, or ACE969.
• Galvanic Isolation: Provides electrical isolation to protect the master computer from surges or faults on the field network.
• Robust Design: Built for industrial environments, ensuring stable data transmission in high-interference areas.

Product Application

The ACE919CA is widely used in Power Distribution Automation and Industrial Control Systems:

• Substation Automation: Connecting protection relays to a SCADA system.
• Network Expansion: Serving as a junction/power point for a bus with up to 12 stations (when using distributed power).
• Marine & Industrial: Used in motor protection and transformer monitoring setups where RS485 communication is standard.

Important Considerations (Precautions)

• Power Source: Ensure the input voltage is within the 110–220 V AC range. For DC-powered requirements, the ACE919CC model should be used instead.
• Wiring Integrity: Use shielded twisted-pair cables for RS485 to minimize electromagnetic interference.
• Distance Limits: While RS485 can reach 1200m, the number of stations and the power draw of connected ACE949/959 modules may reduce the effective distance or station count (typically limited to 12 stations per ACE919).
• Installation: Always turn off the power supply before connecting or disconnecting the terminal blocks to prevent damage to the communication chips.
