Product Introduction
The GE IS220PSCAH1A is a Power Supply Control Assembly (PSCA) module designed for use in GE’s Mark VIe control system, a part of the company’s advanced turbine control solutions. The IS220PSCAH1A module provides regulated low-voltage power and monitoring functions to connected I/O modules, ensuring safe and stable operation in demanding industrial environments. It serves a dual function—both as a regulated power supply and a protective interface for system components.
This model is widely used in high-performance and safety-critical systems such as gas and steam turbines, where consistent power and system protection are essential. It supports system diagnostics, overload protection, and hot-swap functionality, contributing to reduced downtime and improved reliability.
