The GE Fanuc IC694ACC300 is an input simulator module from the RX3i PACSystems series, designed to replicate the operation of real input modules with either 8 or 16 points. While it does not include field connections, it enables developers and engineers to efficiently simulate, test, and debug control system functions without requiring live field wiring. The IC694ACC300 may be employed in development and testing environments across North America, Europe, Asia, and worldwide, where reliable simulation, streamlined troubleshooting, and accurate input behavior replication are essential for PACSystems-based system design and validation.
