Description
Product Overview
The GE IS200SSCAH2A is a high-performance serial communication terminal board designed for GE’s Mark VI/VIe control platform, serving as a critical interface for integrating legacy industrial devices into modern automation systems. This module provides flexible serial connectivity with advanced signal conditioning, enabling seamless integration of RS-232, RS-422, and RS-485 devices in safety-critical applications.
As a core component of GE’s Speedtronic turbine control systems, the GE IS200SSCAH2A supports up to six configurable serial channels, each capable of handling bidirectional data transmission at baud rates up to 375 kbps . Its 48-pin terminal block with screw-type connections ensures reliable termination for field wiring, while 18 jumper switches allow precise configuration of communication parameters such as protocol selection, termination settings, and ground isolation . The module’s compact design (159 mm × 178 mm × 80 mm) and conformal coating make it suitable for harsh environments, including offshore platforms and industrial plants with extreme temperatures (-30°C to +65°C) .
The GE IS200SSCAH2A is engineered for scalability, supporting hot-swap functionality to minimize downtime during maintenance. It integrates with GE’s Mark VIe system via the IS Bus or PROFIBUS-DP, enabling real-time data exchange with controllers and HMIs. Its compatibility with Modbus RTU and Honeywell pressure transducers further enhances its versatility in hybrid control architectures .
