The IC694MDL250 is a discrete input module from the PACSystems RX3i family, designed with individually isolated input channels that enhance system reliability and electrical separation, making it ideal for high-availability applications. In contrast, the IC694MDL240 is a PACSystems RX3i 120 VAC discrete input module, originally produced by GE Intelligent Platforms and now under Emerson Automation. It provides sixteen discrete input channels arranged in a single group, each capable of accepting an input voltage range of 0–132 VAC with a nominal voltage rating of 120 VAC and a typical input current of 12 mA at the rated voltage. The IC694MDL240 and IC694MDL250 may be implemented in industrial control environments across North America, Europe, Asia, and worldwide, where reliable input signal processing, electrical isolation, and consistent performance are critical for robust PAC-based automation systems.
