The IC694MDL660, developed by Emerson Automation and formerly produced by GE Intelligent Platforms, is a 24 VDC discrete input module for the PACSystems RX3i platform, designed to support both positive and negative logic configurations. It features thirty-two (32) input channels organized into four (4) groups of eight (8) channels, providing flexible and efficient signal interfacing for industrial control applications. Each input channel operates within a voltage range of 0–30 VDC and draws an input current of 7.0 mA per point at the rated voltage, ensuring accurate signal detection and stable performance. Compact and reliable, the IC694MDL660 integrates seamlessly into RX3i systems. This input module may be implemented in automation environments across North America, Europe, Asia, and worldwide, where precise DC signal acquisition and logic versatility are essential for advanced process control.
