Product Description (Detailed Explanation)

The ACE919CC serves as an RS485 to RS485 converter. Its primary function is to adapt a standard RS485 serial port from a master system (like a PC or PLC) to a 2-wire RS485 network of Sepam relays.

Unlike a simple bridge, the ACE919CC performs critical signal conditioning tasks:

• Network Polarization: It maintains a stable voltage level on the network lines to prevent data corruption during idle periods.

• Impedance Matching: It ensures the signal quality is maintained across the bus by matching the line impedance.

• Distributed Power Supply: It provides a 12 VDC or 24 VDC auxiliary supply to downstream communication interfaces such as the ACE949-2, ACE959, or ACE969.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• No Flow Control Required: The converter manages the transmission direction automatically, eliminating the need for RTS/CTS hardware flow control signals from the master.

• Built-in Polarization: Simplifies network installation by providing the necessary biasing resistors internally, ensuring clean communication.

• Integrated Power Feed: Acts as a power injector for remote Sepam communication interfaces, reducing the amount of field wiring needed for auxiliary power.

• Galvanic Isolation: Protects sensitive master control equipment from electrical surges and noise generated in the substation or industrial environment.

Precautions (Important Notes)

• Polarization Limit: The RS485 network should only be polarized at one location on the bus. Ensure that other devices on the same line do not also have active polarization resistors to avoid signal degradation.

• DC Power Source: Since this is the “CC” (DC) version, ensure your power source is between 24V and 48V DC. For AC power applications, the ACE919CA model must be used instead.

• Firmware/Compatibility: Specifically designed for Sepam Series 20/40/60/80 communication accessories. Check compatibility if using with third-party Modbus devices.

• Earthing: Always connect the device to the protective earth and functional earth terminals first before connecting communication or power lines.

Product Applications (Typical Use Cases)

• Substation Automation: Linking multiple Sepam protection relays to a central SCADA system for remote monitoring of electrical parameters.

• Power Management Systems (PMS): Feeding real-time data from breakers and transformers to energy management software.

• Industrial Plants: Integrating motor and feeder protection relays into a Modbus network for factory-wide process control.

• Remote Diagnostics: Providing a gateway for technicians to perform remote setting adjustments and fault record retrieval via a central PC.
