Overview
The IC694MDL240 supports 120 VAC input signals for industrial control applications. Therefore, it integrates easily with standard AC-powered field devices and control panels. In addition, optical isolation protects the backplane and CPU from field-side electrical disturbances. Its clear LED indicators provide immediate visual status for each input channel.
