Core Redundant Output Subsystem Component for Genius I/O
The GE Fanuc IC660ERD025C1 and IC660BRD025 represent a single, integrated modular control assembly designed for the Genius I/O platform . This assembly combines the electronics of a DC-powered source block with the modular redundancy sinking output block, serving as the core component of high-reliability control architectures . Primarily, this configuration functions as a modular redundancy sinking output block used within a GMR (Genius Modular Redundancy) output subsystem for demanding industrial automation environments .
Designed for Redundancy and High Reliability
This block is specifically engineered for the H-Block redundant output group, a configuration comprised of two sinking blocks and two source blocks wired in parallel to ensure fail-safe operation . It features 32 discrete output points with integrated blocking diodes and feedback resistors to simplify wiring and boost reliability by preventing reverse drive current faults . The block is configurable for operation at 5, 12, or 24 Volts DC, with a nominal operating current of 0.5 to 1.0 Amp per point, a maximum inrush of 4.0 Amps, and a leakage current of only 20 µA .
