Detailed Feature Overview

GE IC693CPU331-BB provides 240 kB of battery-backed user memory for large programs. This capacity stores complex logic with extensive documentation and comments. The processor executes 1k word of boolean logic in just 0.4 milliseconds. Consequently, it handles high-speed applications like registration control and high-speed counting.

The CPU supports relay ladder logic, sequential function charts, and C programming. This flexibility lets you choose the best method for each task. A 2200 µF capacitor holds memory contents for 30 seconds during battery changes. Therefore, you can replace the lithium cell without losing any program data.

I/O and Communication Capabilities

This CPU module manages up to 2048 discrete I/O points for large systems. It also handles 128 analog inputs and 128 outputs smoothly. Two built-in serial ports connect to programming terminals and HMIs. The RS-485 port supports multi-drop networking with up to 32 devices. Additionally, the processor supports expansion racks up to 150 feet away.

Status Indication and Installation

Five status LEDs provide immediate feedback on processor health. The BATT light warns you when battery voltage runs low. The FAULT LED illuminates for hardware or software errors. Insert the CPU firmly into any Series 90-30 rack slot. Secure it with the two locking levers provided. Operating temperature ranges from 0°C to 60°C reliably. Keep humidity below 95% without condensation for long life.
