GE IC693CHS391H PLC Expansion Base for Series 90-30 Systems

The GE IC693CHS391H adds extra I/O slots to your Series 90-30 PLC system. You can connect this expansion base to the central CPU base via cable. It houses up to ten additional modules for system growth. This base suits applications requiring more I/O than the main rack provides.

Technical Specifications and Hardware Layout

This expansion base measures 127 mm in height. Its width reaches 460 mm, and the depth equals 140 mm. The GE IC693CHS391H weighs approximately 2.4 kilograms. The base includes a passive backplane with ten module slots. It contains no active electronic components or energy storage devices. One 24-pin connector accepts the expansion cable from the CPU base. A separate terminal block provides 5 V DC and 24 V DC power inputs. The base requires no internal battery or capacitor maintenance.

Expansion Capabilities and Compatibility

The GE IC693CHS391H supports all Series 90-30 I/O and specialty modules. It works with digital, analog, and communication cards without restrictions. You can place this base up to 15 meters from the CPU base. Consequently, this flexibility allows optimal cabinet layout and space utilization. The expansion cable carries both data and power to the base unit. Each slot provides standard Series 90-30 backplane signals for seamless integration. The base requires an external power supply for all connected modules.

Installation and Practical Guidelines

You must mount this base horizontally using four M6 screws. Transitioning to wiring, connect the expansion cable to the CPU base firmly. Provide separate 5 V DC and 24 V DC power supplies to the terminal block. Ensure proper grounding to avoid noise coupling into the backplane. The base requires 60 mm of free space above and below for cooling. The operating temperature range spans from 0°C to 60°C reliably.
