IC695ECM850 GE Fanuc RX3i Ethernet Module In Stock

Executive Summary

The IC695ECM850 is an IEC 61850 Ethernet communication module developed for the GE Fanuc PACSystems RX3i controller platform. Functions as an IEC 61850 client interface, this module bridges process automation controllers with electrical substation automation infrastructure, enabling real-time command, telemetry, and event handling over IEC 61850 server devices.

Equipped with 4 switched network ports (2 RJ-45 copper ports and 2 SFP cages), the IC695ECM850 unit supports 10/100/1000 Mbps copper, multi-mode fiber, and single-mode fiber links to maintain high-speed substation data exchange.

Core Architecture & Hardware Layout

The IC695ECM850 integrates a high-performance network processor connected to an internal 4-port Ethernet switch core. This architectural design enables direct connection within star or linear network topologies without requiring external industrial switches.

In addition to fieldbus interfaces, the module incorporates a front-panel Mini-USB port for command-line interface (CLI) administration, an SD card expansion slot for system utilities, and full hot-swappable backplane connectivity for uninterrupted rack maintenance.

Technical Specifications

System Requirements & Slot Installation Rules

To ensure proper operation of the IC695ECM850 within an RX3i rack, adhere to the following hardware and software rules:

• Controller & Rack Constraints
  • Main Rack Only: All IC695ECM850 modules must be installed in the CPU Universal Base Rack (IC695CHS012/016). They are not supported in expansion racks.
  • CPU Capacity: A single RX3i CPU can control up to 4 ECM850 modules simultaneously.
  • Hot-Swap Capability: Supports insertion and removal under power (RIUP) in active RX3i backplanes.
  • Firmware Baseline: Requires RX3i CPU firmware version 8.05 or higher (compatible with CPE305, CPE310, CPU315, CPU320, and CRU320).

Target Equipment, Applications & Diagnostic Capabilities

The IC695ECM850 is designed to connect industrial process automation with electrical power distribution systems.

Target Machinery & Application Scenarios:

• Electrical substation automation linking IEDs (Intelligent Electronic Devices), protection relays, and transformers.
• Power management systems (PMS) in oil refineries, chemical plants, and heavy manufacturing facilities.
• Microgrid control systems integrating renewable energy sources with grid protection networks.
• Large-scale utility supervisory networks requiring precision SNTP time-stamped reporting.

Diagnostic Capabilities:

• LED Status Indicators: Front-panel LEDs for OK, LAN, MODULE, and PORT STATUS for rapid visual troubleshooting.
• Command-Line Interface (CLI): Accessible via the Mini-USB port to perform IP setup, port status checks, and diagnostic dumps.
• SNTP Diagnostics: Verifies time-stamp synchronicity to maintain precise IEC 61850 event logging across protection relays.

Global PLC Spare HUB's Insight

Consider these technical points when engineering or replacing the IC695ECM850 module:

1. Thermal Derating Limits: While the module's standard operating temperature is rated up to 60 °C, installing a 100 Mbps SFP transceiver or a 1 Gbps Copper SFP transceiver lowers the maximum operating limit to 57 °C. Verify cabinet cooling configurations when using these SFP types in high-ambient conditions.

2. Backplane Power Budget Allocation: The module draws 1.2 A at 3.3V DC with no SFPs installed, but power draw rises to 1.9 A at 3.3V DC when 2 SFP transceivers are installed, alongside a constant 1.1 A draw on the 5V DC bus. Check that your RX3i power supply (e.g., IC695PWR400) has sufficient available current capacity on the 3.3V rail prior to adding multiple ECM850 units.

Logistics, Packaging & Warranty Terms

• Quality Protection: Covered by a comprehensive 12 Months Warranty.
• Fast Order Fulfillment: Orders ship from stock within 24 to 48 hours.
• Global Express Courier Delivery: Worldwide air shipping via FedEx, UPS, or DHL.
• Protective Packaging: Enclosed in ESD shielding bags with protective caps over optical SFP slots and copper RJ-45 ports.

Selection Guide & Technical FAQ

Selection Guide: What firmware level is required to support the IC695ECM850 in an existing RX3i system?

The RX3i CPU must run firmware version 8.05 or higher. Programming requires Proficy Machine Edition (PME) 8.0 SIM7 or newer.

How does port derating impact thermal performance when using fiber or copper SFPs?

Using 100 Mbps SFP transceivers or 1 Gbps copper SFP transceivers reduces the upper operating temperature threshold from 60 °C to 57 °C due to additional internal heat dissipation.

Can the IC695ECM850 be installed in an RX3i remote expansion rack?

No. All ECM850 modules must reside in the main Universal Base Rack alongside the RX3i CPU to maintain direct backplane communication speeds.

What is the purpose of the Mini-USB port on the module front panel?

The Mini-USB port provides a direct serial interface to a PC running CLI terminal software for network setup, IP address assignment, and diagnostics.

How does the SNTP protocol benefit IEC 61850 substation applications?

SNTP synchronizes the internal clock across all network nodes, allowing time-stamped sequence-of-events (SOE) data from protection relays to be logged with sub-millisecond accuracy.
