GE IC670GBI002 Field Control Genius Bus Interface Unit

Technical Specifications

• Supply Voltage: 18 to 30 VDC, with a nominal rating of 24 VDC.

• Power Consumption: 16.8 Watts maximum at full load.

• Inrush Current: 15 to 50 Amps peak, with a maximum duration of 3 milliseconds.

• Power Supply Output: Provides 6.5 VDC ±5% to the I/O module backplane, with a maximum current of 1.4 Amps.

• Holdup Time: 10 milliseconds maximum from nominal input voltage.

• Data Exchange Capacity: Supports the exchange of up to 128 bytes of input data and 128 bytes of output data with the host per Genius bus scan.

• I/O Module Capacity: Can manage up to eight Field Control I/O modules in a single station.

• Operating Temperature: 0°C to 55°C (some sources list a wider range of -20°C to 60°C).

• Reliability: Mean Time Between Failures (MTBF) rated at over 183,000 hours.

• Physical Dimensions: Dimensions vary by source; one specification is approximately 233 mm x 178 mm x 45 mm. Weight is approximately 0.5 kg.

Key Functional Features

• Intelligent I/O Processing: Performs I/O scanning, feature configuration, and intelligent processing for all modules within its station. Configuration options include fault reporting, input/output defaults, and analog scaling.

• Comprehensive Diagnostics: Continuously performs diagnostic checks on itself and all connected I/O modules. Diagnostic information is relayed to the host controller and to a connected Hand-held Monitor.

• Redundancy Support: Can operate on a dual Genius bus without the need for an external Bus Switching Module (BSM), as bus-switching circuitry is built into the BIU Terminal Block. It is also compatible with redundant CPU or bus controller configurations for critical applications.

• Genius Datagram Handling: Manages Genius datagram communications, allowing for configuration, monitoring, and control functions beyond standard I/O data exchange.

• Hot Insertion/Removal: Supports the hot insertion and removal of I/O modules, enabling maintenance and module replacement without powering down the entire station or affecting other modules.

• Modular and Rugged Design: The BIU and its I/O modules are housed in sturdy, compact aluminum blocks that bolt securely to separate Terminal Blocks, which provide all field wiring terminals and mount on a standard 35mm DIN rail.

Application Scenarios

• Distributed I/O Systems: Serves as the remote I/O communication hub in manufacturing lines, connecting field devices like sensors and actuators back to a central PLC via the Genius bus network.

• Process Control: Deployed in power generation plants, oil refineries, and chemical processing facilities to monitor and control process parameters such as temperature, pressure, and flow through its connected I/O modules.

• Machine and Robot Control: Used in applications such as CNC machine tools and robotic workcells where local I/O needs to be tightly integrated and managed as a single station.

• Redundant Architectures: Applied in critical control systems where high availability is paramount. Its built-in support for dual bus and redundant CPU configurations ensures continuous operation even if a single communication path fails.
