Genius Series Redundant Output Module System
The IC660BRD025, IC660ERD025, and IC660TBD025 form a complete redundancy sinking output block system for GE Genius I/O. This integrated solution provides fault-tolerant discrete output control for critical industrial applications. The system combines a base block, expansion block, and terminal block. It delivers reliable sinking outputs even during single-component failures.

Redundancy Architecture and Output Control
The system comprises three distinct blocks working together seamlessly. The base block houses the primary control circuitry and communication interface. The expansion block provides additional output channels and failsafe logic. Meanwhile, the terminal block offers convenient screw connections for field wiring. The integrated design automatically switches to the redundant path upon fault detection.
Installation and Configuration
First, mount all three blocks adjacent to each other on the DIN rail. Ensure you connect the inter-block cables securely between modules. Next, wire the field devices to the terminal block screw connections. After that, apply +24 Vdc power and monitor the diagnostic indicators. You can then configure the output mapping through the Genius bus controller.
Maintenance and Operational Reliability
This redundant system ensures continuous output operation even with a single block failure. The built-in diagnostics alert you to any component issues promptly. We recommend you test the failover functionality periodically. You should also inspect the terminal connections and inter-block cables during routine maintenance.
