Product Short Description
Product Introduction
The GE G6M-9UH-00K is a dedicated I/O module paired with the UR9GH CPU module, forming a core component of the GE Multilin Universal Relay (UR) platform, engineered for comprehensive protection, control, and monitoring of power system assets. The UR9GH CPU module serves as the central processing brain, executing high-speed protection algorithms, control logic, and communication protocols, while the G6M-9UH-00K I/O module provides expanded digital I/O capacity for field device integration. The CPU module integrates an 800 MHz processor, 256 MB RAM, and 512 MB flash storage, supporting parallel redundancy protocol (PRP) and IEEE 1588 PTP for secure, time-synchronized communication. The I/O module offers 96 configurable digital inputs and 48 relay outputs with 30 A/250 VAC contact ratings, enabling seamless connection to circuit breakers, switches, and monitoring devices. Both modules feature rugged construction, operating from -40°C to +60°C, with IP30 front panel protection and compliance with IEC 61850, Modbus, DNP3, and IEC 60870-5 standards for global interoperability. They are designed for withdrawable rack mounting, facilitating hot-swapping during maintenance without system shutdown, and are compatible with GE’s EnerVista UR software for intuitive configuration and real-time monitoring.
