GE IC693CPU313 Turbo CPU Review: Specs & Features
GE IC693CPU313 Product Review
The GE IC693CPU313 is a robust 5-slot embedded CPU baseplate from the GE Fanuc Series 90-30 PLC family. It integrates a Turbo CPU directly into the baseplate, eliminating the need for a separate CPU module. This design simplifies system assembly and reduces footprint, making it a practical choice for compact automation projects.
Key Features and Processor Specifications
The embedded CPU relies on an 80188 processor running at 10 MHz. It delivers a typical scan rate of 0.6 milliseconds per 1K of Boolean logic. With a maximum user program memory of 12 KB (6 KB for units before Release 7), it handles moderate control applications efficiently. The baseplate supports shift register, timer, and counter instructions, enabling flexible logic implementation.
I/O Capacity and Expansion
The IC693CPU313 accommodates up to 160 discrete input points and 320 discrete output points (combined) when paired with compatible I/O modules. It also supports 64 words of analog input and 32 words of analog output. However, the baseplate is non-expandable, meaning you cannot attach additional expansion racks. It provides five I/O slots and one dedicated slot for the power supply module on the left edge.
Communication and Protocols
This baseplate includes one built-in serial port. The port supports SNP slave and SNP-X slave protocols. It uses a connector located on the PLC power supply. Note that the IC693CPU313 does not support CCM or PCM modules, so verify compatibility when integrating into an existing system.
Memory Backup and Data Retention
The unit uses RAM for program storage. A battery on the power supply backs up RAM contents. Additionally, a super capacitor provides temporary backup if the power supply is removed or input power fails. For applications requiring more secure nonvolatile storage, you can install optional EPROM or EEPROM modules.
Operating Conditions and Power Requirements
The IC693CPU313 operates in temperatures from 32 to 140 degrees Fahrenheit (0 to 60 degrees Celsius). It draws 410 mA from the +5 VDC bus. The power supply houses the backup battery, and the super capacitor adds an extra layer of memory protection.
Practical Value for Engineers
Although this product is now discontinued and obsolete, it remains relevant for legacy Series 90-30 systems. Engineers maintaining older installations will find the IC693CPU313 a reliable component with straightforward integration. Its embedded CPU reduces wiring and saves panel space. For new designs, consider this module only if you require strict backward compatibility.
