GE Fanuc IC693CHS391 Series 90-30 Modular CPU Baseplate 10-Slot

Product Introduction

When building or expanding a Series 90-30 PLC system, the IC693CHS391 modular CPU baseplate provides the foundation for a reliable control architecture. Manufactured by GE Fanuc, this 10-slot baseplate hosts the CPU, I/O modules, and power supply while enabling local backplane communication. Only one CPU baseplate can be installed per system, making it a critical component for centralized control.

Technical Specifications Breakdown

The IC693CHS391 operates at a voltage rating of 5 Volts DC and draws a current of 420 milliAmperes. It features ten slots: one dedicated CPU slot and nine I/O slots, with the power supply slot unnumbered. A 25-Pin female connector on the right side supports expansion or remote baseplate connections. The default rack address is Rack number 0, and slot assignment places the CPU or specialty module in Slot 1, while I/O or option modules occupy Slots 2 through 10. Panel mounting is the only supported installation method.

Industry Applications

In manufacturing environments, the IC693CHS391 baseplate serves as the central hub for discrete and process control applications. Its ten-slot configuration allows integration of multiple I/O modules, enabling monitoring and control of sensors, actuators, and motor starters. The modular design supports system scalability, making it suitable for both small and medium-sized automation lines. For example, a packaging line can use the CPU slot for logic processing and the nine I/O slots for input modules and output modules, all powered by the 5 VDC backplane.

Installation & Setup Guidance

Mount the IC693CHS391 baseplate on a panel using screws and washers through the provided mounting holes. Install the power supply module in the leftmost unnumbered slot. Insert the CPU only in Slot 1, as this slot is sized for CPU or special option modules like the FIP Bus Remote I/O scanner. Use Slots 2 through 10 for I/O or option modules. Connect expansion or remote baseplates via the 25-pin female connector using a cable less than 700 feet. The baseplate can be oriented vertically or horizontally based on system layout. Ensure the environmental temperature stays within the specified range and protect the unit from water, dust, and chemicals.

Maintenance & Reliability

To maintain reliable operation, periodically inspect the IC693CHS391 baseplate for dust accumulation and loose connections. Keep the enclosure open for airflow but shield it from contaminants. Since the baseplate is discontinued/obsolete, verify availability with BluePLC Industrial before planning replacements. Regular inspection helps extend service life and prevent unexpected downtime.

Compatibility & Integration

The IC693CHS391 works with Series 90-30 PLCs and can connect to a personal computer using a PCI card. It supports up to seven expansion baseplates depending on the CPU model. The expansion baseplate slot allows connection to remote baseplates via the 25-pin female connector. This baseplate cannot function alone; it must be connected to a PLC or a computer with a PCI card.

Selection Guide & Purchasing Advice

Before ordering the IC693CHS391, confirm that your system requires a 10-slot modular CPU baseplate with a 5 VDC backplane. Verify compatibility with your CPU model and power supply. Since this product is discontinued/obsolete, contact BluePLC Industrial to check current stock and find suitable alternatives if needed.
