IC698RMX016 GE Fanuc | Reflective Memory Module

Overview

The GE Fanuc IC698RMX016 Redundant Memory Xchange module is a key component of the RX7i PACSystems series. This 16MB memory module is designed for operation in a reflective memory network or as part of a redundant system linking two CPUs. It offers high-speed data sharing and seamless integration with other GE Fanuc systems.

Features:

• Memory Capacity: 16MB of SDRAM user memory.
• Connectivity: Uses multimode fiber-optic cables with a zirconium ceramic ferrule for stable, high-quality signal transmission.
• Fiber-Optic Connector: LC type, compliant with IEC 61754-20.
• Transmission Loss: Maximum insertion loss of 0.35 dB and return loss of -30dB.
• Temperature Range: Operational range from -20°C to +85°C.
• Redundant System Support: Works within RX7i systems to enable reflective memory operation.
• Configuration: Parameters like Redundant Transfer Mode, Node ID, and Interrupt Enable can be configured as per user requirements (except when using Redundant Link operation).

Technical Specifications:

• Brand: GE Fanuc Automation
• Model: IC698RMX016
• Suffix Meaning: The model name signifies a Redundant Memory Xchange module designed for RX7i PACSystems with specific memory and connectivity features.
• Power Requirements: 5V DC, 1.8A.
• Fiber Optic Cable: Supports multimode fiber-optic cables up to 300 meters long.
