Description

The GE UR9AH stands as the primary processing core for the Multilin Universal Relay (UR) platform. This next-generation CPU module features a high-speed 32-bit processor. Consequently, it delivers a 33% increase in computational speed compared to legacy UR components. This enhanced performance allows for faster logic execution in complex protection schemes. The module also handles the critical conversion of field data into digital commands. Therefore, it remains essential for high-speed automation in modern power grids.

Advanced I/O and Signal Integrity

This processor module provides extensive capacity for both input and output management. It supports up to 64 isolated digital inputs and 32 solid-state outputs. Because the unit maintains ±0.2% voltage accuracy, it ensures highly precise monitoring. Furthermore, the UR9AH features a robust design with EMI resistance up to 10,000 Vrms. This shielding protects the system from electrical interference in heavy industrial zones. It also complies with the IEC 61850-9-2LE standard for digital substation communications.

Safety Certification and Reliability

The UR9AH holds SIL 3 certification for use in safety-critical environments. This makes it ideal for nuclear power, offshore platforms, and railway signaling. The module operates reliably in extreme temperatures ranging from -40°C to +70°C. Additionally, the hardware supports hot-swap functionality to minimize system downtime. Operators can configure the module through EnerVista UR software for rapid deployment. This combination of safety and flexibility significantly reduces maintenance overhead.

Versatile Industrial Application

This CPU module serves a wide variety of sectors requiring stable protection logic. It performs exceptionally well in semiconductor manufacturing and oil and gas facilities. The unit also integrates perfectly into smart city infrastructure projects. Because it uses standard +5V and +24V supply voltages, it fits easily into existing UR chassis. The compact 0.9 kg build ensures easy handling during installation. Overall, the UR9AH provides a reliable foundation for modern industrial automation.
