GE IS220PDIAH1A

The GE IS220PDIAH1A is a Discrete Input Pack designed for use with GE’s Mark VIe series control systems, primarily for turbine control applications. It serves as an interface module to receive digital signals from field devices such as switches, limit switches, and other discrete sensors. The module converts these field signals into a format that can be processed by the Mark VIe control system for monitoring and control logic. It typically features optical isolation on all input channels to enhance system reliability and protect against electrical noise and transients.
