Description
Overview
The IC694MDL660 is a 32-point 24 VDC digital input module for the PACSystems RX3i series. It supports both positive and negative logic inputs and provides selectable input filter times from 0.5 ms to 100 ms. The module is organized into four isolated groups, each with eight inputs and a separate common, ensuring strong electrical isolation for safe and reliable operation in industrial environments. Integrated LED indicators allow immediate visual confirmation of input status.
