The ABB 88TK50B-E GJR2397000R1210 Station Bus Coupling Module is a premium industrial communication interface designed to enable seamless integration between PROCONTROL systems and high-speed FDDI (Fiber Distributed Data Interface) networks. As a trusted product from ABB C, this station bus coupling module is engineered for high-performance, reliability, and compatibility in critical control environments such as power generation, transmission substations, and process industries.

This ABB C station bus coupling module serves as a vital bridge, converting PROCONTROL station bus telegrams into FDDI-compliant frames with error detection and CRC protection. Supporting both single and dual-channel configurations, the ABB 88TK50B-E enables flexible, redundant network designs that enhance the availability and safety of the entire system. It allows distances of up to 2 km between stations, and total FDDI ring lengths up to 100 km—making it ideal for geographically distributed control architectures.

With multiple interfaces including two station bus ports and an FDDI ring port, this coupling module ensures fast and reliable data transmission. It also features diagnostic capabilities, address selection for single or dual mode (addresses 60, 61, 62), and supports 24V DC power modules. Designed for easy installation into standard ABB PROCONTROL cabinets, the module measures 261 x 40 x 198 mm and weighs approximately 0.8 kg.

Built to withstand harsh industrial conditions, the ABB 88TK50B-E GJR2397000R1210 is robust against temperature variations, electrical interference, and mechanical stress. Its integrated monitoring interface enables fast fault detection, preventive maintenance, and real-time diagnostics, helping to reduce downtime and operational risks.

When performance and system uptime are mission-critical, engineers and plant operators trust the ABB 88TK50B-E — a proven, high-quality communication module from ABB C.
