Bus Receiver Module IC697BEM711 Series 90-70 GE Fanuc

Product Overview

The IC697BEM711 is a high-performance Bus Receiver Module engineered by GE Fanuc for the legacy Series 90-70 PLC systems. This module enables dependable multi-rack expansion communication, processing real-time system link traffic over extended physical distances with minimal transit delays.

Key Advantages

• Optimized Latency: Features a low propagation latency of just 1.2 ms to ensure swift, deterministic I/O updates.
• Rugged Interfacing: Equipped with a heavy-duty 25-pin D-sub connector designed to maintain mechanical connection stability in high-vibration control environments.
• Reliable Data Flow: Integrates a 256-byte data buffering capacity to manage traffic queues smoothly and prevent packet dropouts.

Technical Specifications

Quick Installation Tips

• Power down the Series 90-70 backplane entirely before sliding the 1.8 kg hardware assembly into the designated slot.
• Do not exceed the hard limit of 50 feet (15 meters) for the system connection loop to prevent bus communication timing faults.
• Fully secure the thumb screws on the 25-pin D-sub interface connector to preserve optimal signal grounding.

Technical FAQs

Q1: What is the purpose of the 256 bytes data buffer?

A1: It stores transit data temporarily during high-load processor cycles, preventing bottlenecks and guaranteeing an efficient data rate of 500 Kbytes/sec.

Q2: Can this module function in freezing control rooms?

A2: Yes. The board is rated for extended usability across a broad temperature range of -10°C to 60°C (14°F to 140°F).

Q3: How much power does the unit require directly from the backplane?

A3: The module runs on a standard 5 Volts DC input and demands a nominal current draw of 800 mA during full operations.
