Description

The General Electric IC697CPU771 is a high-performance Central Processing Unit (CPU) module designed for the Series 90-70 Programmable Logic Controller (PLC) platform. Featuring an embedded 80C186 microprocessor operating at 12 MHz, this module delivers a Boolean execution time of 0.4 microseconds per function. It serves as the primary controller for industrial automation, managing real-time control of machinery, material handling systems, and complex process automation.

Features

• 12 MHz 80C186 microprocessor architecture.
• Supports up to 2K discrete inputs and outputs (any mix).
• Supports up to 8K analog I/O points.
• 0.4 microseconds per Boolean function execution speed.
• Software-based configuration (no physical DIP switches or jumpers required).
• Three-position operation mode switch for manual control.
• Battery-backed calendar clock for time-stamping and scheduling.
• Three integrated status LED indicators: Module OK, Run, and Outputs Enabled.
• Compatible with VME C.1 Standard format backplanes (IC697CHS750, 782, 783, 790, 791).

Applications

• Gas Turbine Control Systems
• Industrial Process Control and Automation
• Water Treatment Plant Management
• Automotive Assembly and Robotics
• Power Generation and Grid Control

Technical Specifications

Installation Guidelines

• Ensure the PLC rack is powered down before inserting or removing the CPU module to prevent electrical damage.
• The module is designed for installation in slot 1 of the primary rack (Rack 0).
• Handle the module using ESD-safe practices to protect internal circuitry.
• Ensure proper ventilation within the cabinet; maintain clearance around the rack to prevent overheating.
• Use shielded cabling for RS-485 communication to minimize EMI interference from high-voltage equipment.
• Verify that the backplane connectors are clean and free of debris before seating the module.
