GE Fanuc Series 90-30 IC693CPU341 Single-Slot 80KB CPU Module

Product Overview

The GE Fanuc IC693CPU341 is an upgraded, high-efficiency modular CPU engineered for the versatile Series 90-30 PLC platform. Equipped with a high-speed 90C188XL microprocessor running at a 20 MHz clock speed, this module delivers double the processing frequency of entry-level processors. Featuring an expanded 80 Kbytes of user program memory and a rapid typical scan rate of 0.3 milliseconds per 1K of Boolean logic, it is optimized for demanding applications requiring faster execution times and more complex algorithm structures. Weighing 0.45 kg (0.99 lbs), this single-slot CPU easily integrates into the dedicated CPU slot of any standard Series 90-30 baseplate.

Core Technical Advantages

• Accelerated Microprocessing: Built with a 20 MHz 90C188XL clock engine that cuts execution overhead, enabling a fast 0.3 ms scan rate per 1K of Boolean logic for real-time industrial response.
• Expanded Program Memory: Features 80 KB of internal user memory, providing ample space for extensive ladder logic, complex floating-point calculations, and detailed system diagnostics.
• Multi-Baseplate Expandability: Supports up to five (5) baseplates total (one CPU baseplate plus four expansion or remote baseplates) to coordinate multi-rack I/O layouts seamlessly.

Technical Specifications

Installation & Engineering Guide

• Slot Placement & Installation: The 0.45 kg modular CPU must always be inserted into **Slot 1** of a Series 90-30 CPU baseplate. Power off the system entirely before aligning the module inside the chassis channels. Slide the card backward until the connectors are fully mated, and ensure the top and bottom physical clips lock into place to support the module's 0.45 kg frame against mechanical vibrations.
• Expansion Architecture Setup: When expanding the system, the IC693CPU341 allows you to daisy-chain up to 4 additional expansion baseplates via 1756-equivalent or native Series 90-30 expansion cables. Make sure the total length of the expansion bus does not exceed system specification limits to maintain stable signal integrity.
• Data Backup Protocols: The 80 KB RAM memory relies on the lithium backup battery located in the system power supply module. Because program complexity is higher on the CPU341, writing critical programs to an optional EEPROM chip is highly recommended to protect your logic from unexpected battery failure.

Technical FAQs

Q1: What are the main benefits of upgrading from the CPU331 to the IC693CPU341?
A1: The IC693CPU341 doubles the microprocessor speed from 10 MHz to 20 MHz, dropping the logic scan rate to 0.3 ms. It also offers five times more user memory (80 KB compared to 16 KB), allowing for much larger data register blocks and more comprehensive program structures.

Q2: Does the IC693CPU341 require a dedicated slot, or can I install it anywhere to save space?
A2: It is a single-slot CPU, but it cannot be placed in standard I/O slots. It must be installed in **Slot 1** of a dedicated CPU baseplate (either 5-slot or 10-slot models). Other slots are reserved for discrete, analog, and communication modules.

Q3: How robust is the physical construction of this 0.45 kg module?
A3: The 0.45 kg weight reflects its robust industrial casing and integrated metal shield plates, which protect the sensitive 90C188XL processor from electromagnetic interference (EMI). Its secure mechanical latching mechanism keeps the card tightly seated in high-vibration manufacturing environments.
