Description

The GE Intelligent Platforms IC800SSI228RD2 is a highly versatile, two-channel Serial Synchronous Interface (SSI) module designed for the VersaMax Micro and Nano PLC systems. This specialized module serves as a critical interface between the PLC and high-precision absolute position sensors that utilize the SSI protocol. The primary function of the GE Intelligent Platforms IC800SSI228RD2 is to read absolute positional data—such as linear displacement or angular rotation—directly from SSI-equipped encoders, resolvers, or other measuring devices, providing the control system with accurate and reliable feedback without the need for a battery-backed-up home reference.

As part of the VersaMax family, this module is engineered for applications requiring compact size and cost-effectiveness without sacrificing critical functionality. The “RD2” suffix typically indicates a specific revision or a two-channel redundant-capable design, though its core value lies in its ability to handle two independent SSI sensors simultaneously. The GE Intelligent Platforms IC800SSI228RD2 converts the serial data stream from the sensors into a numerical value that can be easily used within the PLC’s logic for precise motion control, positioning, and monitoring tasks. Its integration into the VersaMax system allows for a seamless flow of high-resolution positional data, making it an ideal solution for machine builders in packaging, material handling, and assembly automation.

Main Features and Advantages

The GE Intelligent Platforms IC800SSI228RD2 offers several key advantages for precision applications. Its most significant feature is the support for two independent SSI channels on a single, compact module. This dual-channel capability allows a single PLC to interface with two critical position sensors—for example, one for X-axis and one for Y-axis positioning—reducing hardware costs and simplifying control cabinet layout compared to using two single-channel modules. The module supports high-resolution data, handling up to 32-bit values from the sensors, which is essential for applications requiring micron-level accuracy or very fine angular resolution.

The programmability of the SSI clock frequency is a major advantage, providing the flexibility to communicate with a wide range of SSI sensors from different manufacturers without compatibility issues. Each channel can be individually configured for its own sensor supply voltage (5V or 24V), offering great flexibility in sensor selection. The IC800SSI228RD2 includes diagnostic LEDs for each channel, providing immediate visual feedback on communication status and simplifying troubleshooting. By providing direct, absolute position feedback to the PLC, the GE Intelligent Platforms IC800SSI228RD2 eliminates the potential for cumulative errors inherent in incremental encoder systems, ensuring consistent and reliable machine operation after power cycles.

Application Field

The GE Intelligent Platforms IC800SSI228RD2 is deployed in a wide array of applications that demand high-precision absolute positioning. In packaging machinery, it is used to read the absolute position of forming jaws, sealing heads, or product gates, ensuring precise coordination for filling and sealing operations. In material handling, the module interfaces with SSI encoders on rotary tables, linear actuators, or automated storage and retrieval systems (ASRS) to determine the exact position of loads, enabling accurate placement and retrieval.

In industrial crane and hoist systems, the IC800SSI228RD2 provides absolute feedback for trolley and hook position, which is critical for automated lifting and moving sequences. The module is also ideal for use in test and measurement equipment, where precise angular or linear displacement must be recorded. Furthermore, in printing and converting machinery, it ensures accurate registration and web alignment by providing absolute feedback from the main line shaft or individual axis drives. The robustness and reliability of the IC800SSI228RD2 make it suitable for these demanding environments where positional accuracy is directly linked to product quality and operational efficiency.
