Product Introduction
The GE IC693CPU331 is a modular CPU designed for the Series 90-30 PLC family from GE Fanuc Automation. This single-slot processor replaces older fixed CPUs or serves as a direct upgrade for systems requiring higher performance and expanded I/O capacity. With an 80188 microprocessor running at 10 MHz and 16 Kbytes of user memory, the IC693CPU331 handles up to 512 discrete inputs, 512 discrete outputs, 128 words of analog inputs, and 64 words of analog outputs—ideal for medium-complexity automation tasks.
Technical Specifications Breakdown
The IC693CPU331 delivers consistent performance in demanding industrial environments. Key specifications include:
-
Processor: 80188 at 10 MHz
-
User Memory: 16 Kbytes (RAM, optional EPROM/EEPROM)
-
Typical Scan Rate: 0.4 ms per 1K of Boolean logic
-
Discrete I/O: 512 inputs / 512 outputs
-
Analog I/O: 128 input words / 64 output words
-
Timers/Counters: 680
-
Serial Ports: 1 (SNP slave/SNP-X slave)
-
Current Load: 350 mA @ +5 VDC
-
Operating Temperature: 32 to 140 °F (0 to 60 °C)
These parameters make the IC693CPU330 (note: correct model is IC693CPU331) a reliable choice for applications requiring fast logic execution and expanded I/O handling. The built-in serial port supports SNP and SNP-X slave protocols, while additional communication modules can be added for master or other protocols.
Industry Applications
The GE IC693CPU331 excels in industries such as manufacturing, water treatment, and material handling. For example, a packaging line can benefit from the processor's 0.4 ms scan rate to synchronize high-speed conveyors and actuators. In a wastewater treatment plant, the CPU's 128 analog input words allow precise monitoring of flow and pressure sensors. The modular design enables easy integration into existing Series 90-30 racks, whether upgrading from a smaller CPU or replacing a failed unit.
Installation & Setup Guidance
Installing the IC693CPU331 is straightforward. The module fits into slot 1 of any 5-slot or 10-slot Series 90-30 baseplate. Ensure the backplane provides +5 VDC with at least 350 mA capacity. Insert the CPU into the dedicated slot, apply power, and validate communication via the built-in serial port using SNP or SNP-X protocols. For expanded I/O, connect up to four expansion or remote I/O baseplates. Always verify the firmware version and configure the memory type (RAM, EPROM, or EEPROM) per your application requirements.
Compatibility & Integration
The IC693CPU331 is fully compatible with all GE Fanuc Series 90-30 rack systems and I/O modules. It supports up to four expansion baseplates or remote I/O baseplates. The single serial port is accessible via the power supply connector and supports SNP slave and SNP-X slave protocols. For additional serial ports or master protocol support (SNP master, CCM, RTU), install a CMM module (e.g., IC693CMM301) or a PCM module. The SLP (State Logic Processor) can also be added for multi-tasking control. No proprietary software is required beyond the standard Logicmaster 90-30 or Proficy Machine Edition.
Selection Guide & Purchasing Advice
Before purchasing the GE IC693CPU331, verify that your baseplate has an available slot 1 and that your power supply can deliver the required 350 mA at +5 VDC. If you need additional communication ports or master protocol support, order a CMM or PCM module separately. For long-term reliability, consider installing an optional EPROM or EEPROM to retain program memory. UBEST Automation offers the IC693CPU331 with fast shipping and dedicated support. Ensure your existing I/O configuration does not exceed the CPU's limits (512 DI, 512 DO, 128 AI, 64 AO). For any compatibility questions, contact our technical team.
