General Electric DS200DTBDG1ABB Contact Output Expansion Termination

Description

The General Electric DS200DTBDG1ABB Contact Output Expansion Termination is a terminal relay board and analog I/O board belonging to the DS200 series, designed for use in gas turbine control systems. It offers flexible physical layer connectivity options, including copper wire RJ45 connectors, copper wire M8 connectors, single-mode fiber interfaces, multi-mode fiber interfaces, and plastic optical fiber (POF) interfaces, allowing adaptation to diverse installation and communication requirements. Key features include ID switches for configuring variable topologies, hot connect and fast hot connect technology for seamless topology modifications, and integrated digital and safety I/O for space-saving compact solutions. It also supports extended distance connectivity up to 300 meters, with a metal enclosure and built-in diagnostic functions to enable high-precision analog measurements. Functionally, it handles power distribution via 2PL to core components, and uses 3PL as a data bus to connect core boards such as STCA, TCQA, and TCQE, transmitting conditioned signals to the COREBUS. It manages multiple signal types: thermocouple inputs and cold junction compensation via JA connectors, 4-20 mA I/O signals via JB connectors, trip signals to TCTG boards via JD connectors, pulse, generator, line, relay driver, and servo valve driver signals via JE connectors, LVDT/LVDR position inputs via JF connectors, and +/-10 V DC inputs plus vibration inputs via JG connectors.
