GE IC695CRU320CA-EL Controller Module

1. Overview

The IS200ERDDH1ABA is a Digital Input/Output

The GE IC695CRU320CA-EL is a high-performance central processing unit (CPU) module from the GE Fanuc PACSystems RX3i line, designed for demanding industrial automation applications. With hot-standby redundancy capability, generous user memory, and broad communication support, this controller serves as the “brain” of complex control systems where uptime, flexibility, and performance are critical.
It enables migration from legacy GE Series 90-30 I/O systems while delivering modern architecture for Ethernet, serial, I/O and redundancy networks.

Technical Specifications

• Processor: 1.0 GHz (Intel Celeron-M class) typical for the IC695CRU320 family.

• Memory: 64 MB non-volatile flash plus 64 MB battery-backed RAM (user program/data) in standard CRU320 units. 

• Serial Ports: Two built-in serial communications ports (one RS-232, one RS-485) supporting SNP, Modbus RTU Slave, Serial I/O protocols.

• Redundancy: Supports hot-standby CPU redundancy with switchover times down to 3.133 ms minimum or within a single logic scan at most. 

• I/O Expansion: Compatible with RX3i PCI backplane architecture and supports Series 90-30 expansion racks (in certain configurations) for migration. 

• Operating Temperature & Environment: Typical 0 °C to +60 °C for standard unit listings (−40 °C to +70 °C for some vendor-advertised versions). 

• Form Factor & Mounting: Module designed for RX3i rack insertion; occupies appropriate backplane slot(s). Weight approx. 0.94 kg (2.06 lb) for standard CRU320 version.

  
  

Key Features

• High-Availability Architecture: The EL revision supports the CRU320 feature set including hot standby redundancy, making it suitable for mission-critical processes.

• Large Program & Data Capacity: With up to 64 MB flash and 64 MB RAM, it can handle extensive logic, data logging, and communication tasks.

• Flexible Communications: Serial ports built-in; expanded Ethernet and PROFINET connectivity possible via dedicated interface modules.

• Legacy Migration Support: Allows reuse of Series 90-30 I/O while upgrading to RX3i performance levels, reducing wiring and cost.

• Robust Diagnostics & Monitoring: LEDs for RUN, CPU OK, FORCE, I/O statuses, aiding maintenance and fault detection.

• Firmware Upgradeable: Field-upgradeable firmware allows enhancements for Ethernet, PROFINET, IEC 61850, HART pass-through as options.

Structure & Composition

Internally, the IC695CRU320CA-EL module includes:

• A high-speed microprocessor board with integrated memory, flash storage, and system logic.

• Dual serial port interfaces on the front panel for field and host communication.

• Status LED bank (e.g., CPU OK, RUN, Outputs Enabled, I/O Force, System Fault, COM ports) for operational monitoring.

• Backplane connector for RX3i universal rack, facilitating power, data, and I/O connectivity.

• Battery-backed memory system to retain user data and clock during power interruption.

• Firmware and configuration memory managed via Proficy Machine Edition software environment.

  
  

Applications

The GE IC695CRU320CA-EL is ideal for automation systems where reliability, scalability and communication interoperability are required, such as:

• Power generation and process plants (turbines, boilers, substations)

• Petrochemical and oil & gas modules

• Machine automation and large-scale discrete manufacturing

• Water & wastewater treatment plants

• Any application requiring redundancy and migration from legacy systems

Installation & Maintenance

Installation:

1. Power down the backplane and ensure proper ESD protection when handling the module.

2. Slide the IC695CRU320CA-EL into its designated RX3i rack slot fully engaging the backplane connector.

3. Connect built-in serial port cables if used and ensure any external Ethernet or PROFINET modules are wired.

4. Configure firmware version, battery pack and network settings in Proficy Machine Edition.

5. Power up and observe LED bank: CPU OK should be illuminated, RUN should show active processing.

   
   

Maintenance:

• Replace the battery pack per manufacturer recommendation to avoid memory retention failure.

• Periodically monitor system fault logs and firmware version; upgrade if vulnerability or compatibility issues arise.

• Inspect rack cooling, dust accumulation and connector integrity to ensure reliable service.

• Ensure backup of program and configuration data regularly and keep duplicate module on standby if redundancy required.

Additional Information & Compliance

The module complies with industrial automation standards including hot-standby redundancy requirements outlined in the RX3i CPU Reference Manual (GFK-2514). 
Its firmware revision “EL” (7.18, Nov. 2012) added monitoring capabilities for interface between CPU and CMX/RMX Memory Xchange modules. 
Given its open module design, the unit must be installed in a suitable enclosed cabinet (Pollution Degree-2 environment) when used in hazardous or demanding conditions
