Description
Product Description
The IC694MDL241 by GE (Emerson Automation) is a 16-point discrete input module designed for the PACSystems RX3i platform. It accommodates both AC and DC field signals and supports positive or negative logic in DC mode. This module is compatible with a broad range of industrial input devices including pushbuttons, limit switches, and proximity sensors. Sixteen dedicated green LEDs provide clear, real-time status indication for each input channel.
The module features optical isolation between field inputs and the backplane, ensuring reliable operation in electrically noisy industrial environments. Installation is flexible, fitting any RX3i I/O slot, and supports hot-swappable insertion and removal without powering down the system.
