The GE IC800SSI228RD2 is a high-performance programmable automation controller from GE’s VersaMax® Micro PLC series, designed for precision motion control and industrial networking applications. This 28-point I/O module integrates SSI (Synchronous Serial Interface) encoder inputs with 24VDC sinking outputs, providing ±1LSB resolution for absolute position feedback systems. The IC800SSI228RD2 serves as a critical component in GE’s PACSystems™ architecture, enabling seamless integration of servo drives and smart sensors through built-in Profibus-DP and Modbus RTU protocols.
As part of the IC800SSI modular I/O family, this configuration supports 2 SSI channels with 32-bit counter resolution and 1MHz sampling rate, making it ideal for rotary table positioning and linear encoder interfaces. Its dual-port Ethernet switch allows daisy-chain connectivity while maintaining <1ms cycle times for deterministic control. The module’s -40°C to +70°C operational range ensures reliability in harsh environments like steel rolling mills and offshore drilling platforms.

Key Features and Advantages:
Precision motion interface: The GE IC800SSI228RD2 achieves 0.03° angular resolution through its 32-bit SSI decoding, supporting Gray code and binary data formats. Built-in cable fault detection identifies open/short circuits in encoder wiring up to 300m.
Industrial networking versatility: Simultaneous operation of Profibus-DP (12Mbps) and Modbus RTU (115.2kbps) enables hybrid fieldbus architectures. The embedded web server provides real-time diagnostics via standard browsers without additional software.
Ruggedized construction: Military-grade components withstand 5g vibration (10-150Hz) and 50g shock pulses. The gold-plated SSI connectors ensure <10mΩ contact resistance after 10,000 mating cycles.

Installation and Maintenance:
Installation preparation: Verify encoder SSI clock compatibility (500kHz max for most absolute encoders) before connecting to the GE IC800SSI228RD2. Use Belden 9729 twisted-pair cable for SSI signals and maintain 30cm separation from AC power lines.
Maintenance recommendations: Clean air vents quarterly in dusty environments using dry compressed air (<30psi). Update firmware via Proficy Machine Edition software during planned shutdowns. Perform annual relay contact resistance measurement (<100mΩ).
