Alstom 502476L (KCEU14201F51PEB) Control Unit Module for MV/HV Switchgear Systems

Product Description

The Alstom 502476L (Part Code: KCEU14201F51PEB) is a high-reliability control unit module specifically engineered for Alstom medium-voltage (MV) and high-voltage (HV) switchgear systems, including GIS (Gas Insulated Switchgear) and AIS (Air Insulated Switchgear) solutions. As a core logic and control component, this module integrates digital input/output processing, protective relaying logic, and communication capabilities to manage switchgear operations (e.g., circuit breaker tripping/closing, isolator control, earth switch monitoring). Powered by 24 VDC, it features robust galvanic isolation between field and control circuits, built-in fault diagnostics, and compliance with IEC 61850 and IEC 60255 standards. Ideal for power distribution networks, substations, industrial plants, and renewable energy facilities, the 502476L ensures safe, reliable control of MV/HV switchgear in critical power infrastructure applications.

Key Functions

The 502476L control unit module delivers comprehensive logic control and monitoring for MV/HV switchgear systems. Key functions include: Integrated digital I/O processing (16 digital inputs, 8 digital outputs) for switchgear status monitoring and control; protective relaying logic (overcurrent, under/over voltage, earth fault detection) for circuit breaker protection; galvanic isolation (2500 VAC) between field circuits and control electronics to prevent electrical interference; built-in self-diagnostics and fault logging for module health monitoring; support for IEC 61850-8-1 (MMS) and IEC 60870-5-104 communication protocols for substation automation integration; 24 VDC redundant power input for high availability; and compliance with IEC 61850, IEC 60255, and IEEE C37 standards. The module also features LED status indicators for power, communication, and fault conditions, and pluggable terminal blocks for easy maintenance.

Application Scenarios

The Alstom 502476L control unit module is primarily deployed in MV/HV switchgear systems across critical power infrastructure applications. In utility substations, it controls GIS/AIS switchgear for power distribution, transmission, and grid stability management. For industrial plants (steel, chemical, manufacturing), it manages on-site MV switchgear for motor control centers, transformer protection, and emergency power systems. In renewable energy facilities (solar, wind), it integrates with grid-tie switchgear to ensure safe power injection and fault isolation. The module is also used in data centers, commercial buildings, and railway electrification systems—all scenarios requiring reliable, standards-compliant control of MV/HV switchgear for power system safety and efficiency.
