GE IC693ADC311D Co-Processor Module for Series 90-30 PLCs

The GE IC693ADC311D adds advanced processing power to Series 90-30 PLC systems. You can install this module directly into any standard 90-30 rack slot. It handles complex arithmetic and data manipulation tasks. This co-processor offloads intensive calculations from the main CPU.

Technical Specifications and Hardware Layout

This co-processor module measures 127 mm in height. Its width reaches 55 mm, and the depth equals 140 mm. The GE IC693ADC311D weighs approximately 0.38 kilograms. A single internal PCB holds the auxiliary processor and memory circuits. The module contains no energy storage capacitors or batteries. One 48-pin edge connector interfaces directly with the 90-30 backplane. One 9-pin D-sub port provides a programming and debug interface. Two status LEDs indicate power and co-processor activity.

Processing Capabilities and Performance

The GE IC693ADC311D executes advanced math and string handling functions. It communicates with the main CPU through shared memory buffers. This co-processor performs floating-point calculations and PID algorithm processing. Consequently, the main CPU focuses on core logic and I/O scanning tasks. The module includes 128 KB of dedicated program memory. It also provides 64 KB of data storage for complex applications. You can program this co-processor using C or assembly language.

Installation and Programming Guidelines

You must insert this module into any standard 90-30 rack slot. Transitioning to programming, connect a PC to the debug port with a serial cable. The module supports online code updates without stopping the main PLC. Two front LEDs show module health and communication status. Always power off the PLC before removing or inserting the module. The operating temperature range spans from 0°C to 60°C reliably.
