GE Fanuc IC660BRD025 Genius Modular Redundancy Sinking Output Block

Technical Specifications Breakdown

Key parameters for the IC660BRD025 are listed below for quick reference:

Industry Applications for the GMR Output Block

In an H-Block output group configuration, two IC660BRD025 sinking output blocks are wired in parallel on one side of each load, while two source blocks are on the other side. This setup ensures that if one block fails, the parallel block continues operation, minimizing downtime. The 32 output points handle up to 1.0 Amp each, making them suitable for driving solenoids, relays, and indicator lights in demanding environments.

Installation and Setup Guidance

When installing the IC660BRD025, ensure the Genius I/O bus is configured to match the GMR setting using the Genius Handheld Monitor. The block is designed for use in a GMR output group, which performs voting by comparing output data for each of the 32 points as received from the PLCs. Unlike input subsystems that use software voting, this output group relies on hardware comparison for fault tolerance. Verify that the operating voltage (5 to 48 Volts DC) matches your field device requirements, and that the load current does not exceed 1.0 Amp per point.

Maintenance and Reliability

The built-in blocking diodes and feedback resistors enhance system reliability by preventing malfunction due to back-drive current. For long-term reliability, periodically inspect the block for signs of environmental stress, such as moisture or dust buildup on the bus connector. Ensure that the inrush current (max 4.0 Amps) does not exceed the block's rating during initial load energization. The component is designed for continuous operation in industrial settings, but routine checks of the GMR configuration and wiring integrity are recommended.

The Challenge of Reliable Redundant Output Control

In critical industrial processes, a single output failure can lead to costly downtime or safety hazards. This component is designed to control discrete output loads with high reliability, leveraging built-in blocking diodes and feedback resistors to simplify wiring and prevent back-drive current issues.

Compatibility and Integration

It supports H-Block output group configurations, which are part of the GMR output subsystem. This block is specifically a current sinking type, meaning it sinks current from the output field devices. For proper operation, pair it with source blocks in the same H-Block group. The 32-point capacity allows for efficient control of multiple loads from a single module.

Selection Guide and Purchasing Advice

When selecting the IC660BRD025 for your system, confirm that your application requires a sinking output block for a GMR output subsystem. For availability and lifecycle status, please verify with AutoDCSTech before ordering. AutoDCSTech offers this part along with other Genius I/O modules to support your automation needs.
