ABB COM0011 Communication Module 2RAA005844A0007J

Technical Parameters:

Communication Interfaces: Integrated multi-port interface topology featuring 1x RJ45 Ethernet port (10/100 Mbps auto-negotiation), 1x RS-485 serial terminal connector, and 1x IRIG-B BNC connector for microsecond-level clock synchronization.

Supported Communication Protocols: Native protocol bridging capabilities supporting Modbus RTU/TCP, IEC 60870-5-104, Ethernet/IP, and standard telemetry streaming.

Time Synchronization: Standard IRIG-B port supporting precise time stamping for event recording across network nodes.

Operating Power Supply: Sourced via internal system backplane connection or standard 24 V DC auxiliary power input.

Galvanic Isolation & Shielding: Reinforced optical and electrical isolation against high-voltage line surges, electro-static discharges (ESD), and severe electromagnetic interference (EMI).

Operating Temperature Range: Built for continuous operation across industrial thermal environments ranging from -20°C to +60°C.

Protection Rating & Mounting: Enclosed in a compact IP20-rated chassis (approx. 95 mm x 63 mm x 24 mm, weighing ~0.1 kg) designed for standard 35 mm DIN-rail or system slot mounting.

Industrial Sectors:

Electric Power Substation Automation, Renewable Energy (Wind and Solar Farms), Oil and Gas Refining, Chemical Processing, Utility Distribution Networks, and Heavy Manufacturing Automation.

Application Scenarios:

1. Substation Telemetry & Time Synchronization: Installed inside power protection cabinets to interface intelligent electronic devices (IEDs) with central SCADA platforms while ensuring precise time-synchronized event logging via IRIG-B.

2. Industrial Fieldbus-to-Ethernet Gateway: Positioned in remote control panels to bridge RS-485 field instrumentation and serial networks to high-speed Ethernet topologies.

3. Renewable Generation Plant Networking: Deployed in wind turbine enclosures and solar inverter stations to transmit operational telemetry, fault alarms, and status checks to regional control centers.

4. Distributed Control System (DCS) Expansion: Utilized inside ABB automation racks to extend local communication capabilities, adding multi-protocol interface options without requiring central processor modifications.
