General Electric (GE) is a multinational industrial and technology services company founded in 1892 and headquartered in Westport, Connecticut, United States. With a wide range of businesses, including aviation, power, healthcare, transportation, oil and gas, renewable energy, construction and financial services, GE is one of the world’s largest industrial companies with more than 300,000 employees.

The IS200EROCH1A, part of the GE EX2100 series, is an excitation regulator TAB with data transfer capability that can be connected to two locations on the regulator rack. The module is designed to support regulator options, third-party GE ground detectors, and terminal board power connections. In addition, the IS200ERGTH1A model can be connected to the IS200EROCH1A module to detect ground resistance leakage of the generator’s excitation current. With two backplane connectors, four high-voltage electrolytic capacitors and a CPU socket, and a keyboard connector designed to connect RS-232 cables, this module provides a flexible solution to meet the data transmission and communication needs of industrial control systems.
