Product Overview
The GE IC693CPU331 is a modular Central Processing Unit (CPU) module that plays a pivotal role in GE’s Series 90 – 30 Programmable Logic Controller (PLC) systems. Engineered by GE Fanuc, this single – slot module is designed to offer reliable and efficient control capabilities for a wide range of industrial automation applications.
Equipped with an 80188 processor running at a clock speed of 10 MHz, the IC693CPU331 ensures swift execution of control programs. It provides users with a maximum user program memory of 16 kbytes, which is sufficient to handle complex control logic. This CPU module can support an extensive array of input and output configurations, with 512 discrete inputs, 512 discrete outputs, 128 analog input words, and 64 analog output words. It also comes with 680 units of timers/counters, enabling precise time – based control operations. In terms of communication, it features one serial port that supports SNP/SNP – X slave protocols, allowing for seamless integration with other devices in the industrial network.
The GE IC693CPU331 is a versatile solution that can be installed in either 5 – slot or 10 – slot baseplates, but it must be placed in the dedicated CPU slot, which is slot 1. It draws a current of 350 mA from the backplane at a bus voltage of +5 VDC. Its design allows for system expansion, with the support of up to four expansion baseplates or remote I/O baseplates, making it adaptable to growing industrial control requirements.

Main Features and Advantages
High – Performance Processing
The 10 MHz 80188 processor in the GE IC693CPU331 enables rapid processing of control programs. With a typical scan rate of 0.4 milliseconds per 1 k of boolean logic, it can quickly respond to input changes and execute control actions. This high – speed processing is crucial for applications where real – time control is essential, such as high – speed manufacturing lines or processes that require precise timing.
Ample Memory and I/O Capacity
Featuring 16 kbytes of user program memory, the IC693CPU331 can store extensive control logic. The large number of discrete and analog I/O points (512 discrete inputs, 512 discrete outputs, 128 analog input words, and 64 analog output words) allows it to interface with a wide variety of sensors, actuators, and other field devices. This makes it suitable for complex industrial applications that demand comprehensive data acquisition and control.
Expandability
The ability to support up to four expansion baseplates or remote I/O baseplates gives the GE IC693CPU331 great flexibility. As industrial processes grow or change, additional I/O modules can be easily added to the system. This expansion capability ensures that the CPU module can adapt to evolving requirements without the need for a complete system overhaul, saving both time and costs.
Built – in Communication
The single serial port, which supports SNP/SNP – X slave protocols, provides a reliable means of communication with other components in the industrial network. This allows for seamless integration with other devices, such as HMIs (Human – Machine Interfaces), other PLCs, or sensors and actuators that support these protocols. It enables efficient data transfer and coordination within the overall industrial control system.
Battery – Backed Clock
The IC693CPU331 comes with a battery – backed clock. This feature is beneficial for applications that require time – stamping of events or rely on time – based control operations. Even during power outages, the clock continues to function, ensuring that time – sensitive data and operations are not disrupted.

For example, in an automotive assembly line, the CPU module can control the movement of robotic arms to precisely assemble car parts. It can also monitor and adjust the speed of conveyor belts based on the production rate, ensuring smooth and efficient production. In a food and beverage manufacturing plant, it can control the filling and packaging processes, ensuring accurate filling levels and proper packaging.
Power Generation
Power plants, whether they are thermal, hydro, or wind – powered, rely on the IC693CPU331 for various control tasks. It can monitor and control the operation of generators, turbines, and other power – generating equipment. In a thermal power plant, the CPU module can regulate the combustion process by controlling the fuel supply and air intake based on parameters such as temperature and pressure. In a wind power plant, it can adjust the pitch of the wind turbine blades and the rotation speed of the generator to optimize power generation according to wind speed and direction.
Oil and Gas Industry
In the oil and gas industry, the GE IC693CPU331 is used in oil refineries, gas processing plants, and pipeline systems. It can control the operation of pumps, compressors, and valves. For instance, in an oil refinery, the CPU module can monitor and control the distillation process, ensuring the production of high – quality fuels and other petroleum products. In a gas pipeline system, it can regulate the flow of gas by controlling the opening and closing of valves based on pressure and flow rate data.
