IS200ERIOH1ACB 是由美国通用电气公司（GE）制造的可编程控制器，主要用于Mark VI汽轮机调节系统中的EX2100励磁系统。该板卡作为EX2100调节控制系统的核心组件，提供灵活的输入/输出（I/O）接口，适用于单工和冗余应用。

IS200ERIOH1ACB 是一个关键的励磁调节I/O板，确保了励磁控制系统的平稳运行。它在Mark VI汽轮机监督系统中扮演着重要角色，特别是Speedtronic燃气/蒸汽涡轮机监督系统。

IS200ERIOH1ACB is a programmable controller manufactured by General Electric (GE) in the United States, mainly used for the EX2100 excitation system in the Mark VI turbine control system. This board serves as the core component of the EX2100 control system, providing flexible input/output (I/O) interfaces suitable for simplex and redundant applications.

IS200ERIOH1ACB is a critical excitation regulation I/O board that ensures the smooth operation of the excitation control system. It plays an important role in the Mark VI turbine supervision system, especially the Speedtronic gas/steam turbine supervision system. This product has been widely used since the release of the MKI model in 1969, until the production of the Mk VI model ceased in the late 1990s.
