General Electric IC695CRU320 PACSystems RX3i Redundancy CPU Processor Module

Description

The General Electric IC695CRU320 is a high-performance Redundancy CPU processor module designed for the PACSystems RX3i platform. Engineered for critical industrial applications, this module facilitates hot-standby configurations, significantly increasing system availability. In a redundant setup, the IC695CRU320 manages the synchronization between two controller racks, allowing for an automatic, seamless transfer of control from a primary rack to a secondary rack in the event of a fault. This transition occurs in a maximum of one logic scan, with a minimum switchover time of 3.133 ms.

Features

• Processor: Intel Celeron M at 1 GHz clock speed.
• Memory: 64 MB of battery-backed RAM and 64 MB of non-volatile flash user memory.
• Redundancy Support: Designed for hot-standby configurations; supports synchronization via IC695RMX128/228 modules.
• Communication: Equipped with two serial ports supporting RS-232 and RS-485 standards.
• Data Integrity: Features Error Checking and Correction (ECC) for RAM and read-only program protection during execution.
• Diagnostics: Includes a dedicated System Fault (Sys Flt) LED and an I/O Force indicator for enhanced troubleshooting.

Applications

The IC695CRU320 is intended for large-scale, complex automation processes where downtime must be minimized. It is widely used in power generation, oil and gas, and large-scale manufacturing environments where redundant control logic is required to maintain operational continuity.

Technical Specifications

Installation Guidelines

• Power: Ensure all power is disconnected from the rack before inserting or removing the module.
• Mounting: This module occupies two slots in the RX3i rack. Ensure it is fully seated and secured using the integrated latches.
• Environment: Install in a clean, dry, and protected NEMA/UL Type 1 enclosure to prevent exposure to dust, moisture, and corrosive elements.
• Grounding: Follow standard industrial grounding practices for the RX3i backplane to ensure electrical noise immunity.
• Battery: Requires an external high-capacity battery (IC693ACC302) to maintain RAM data during power loss.

FAQ

What is the primary purpose of the IC695CRU320?

It is a Redundancy CPU that allows a backup unit to take over automatically if the primary controller fails, ensuring minimal process disruption.

What hardware is required for the redundant IC695CRU320?

Each unit must be configured with a redundant memory exchange (RMX) module (IC695RMX128/228) to facilitate data synchronization.

What is the IC695CRU320 operating temperature?

The module is designed to operate in temperatures ranging from 0 to 60 degC (32 to 140 degF).
