IMDSI14 Digital Input Module

Features

Signal Acquisition and Transmission
The IMDSI14 module serves as a 16-channel digital input interface for industrial control systems. It introduces independent digital signals from external devices—such as position sensors, start/stop switches, and limit switches—into the controller. This enables real-time monitoring and control of production processes with high reliability and precision.

Status Indication
The front panel is equipped with 16 LED status indicators, organized into Group A and Group B. These LEDs provide clear visual feedback on the operating status of each input channel, simplifying system testing, troubleshooting, and maintenance.

Strong Anti-Interference Capability
Designed for industrial environments, the IMDSI14 features an optimized input circuit with high immunity to electromagnetic interference (EMI), power fluctuations, and other common electrical disturbances. This ensures accurate, stable signal acquisition and transmission under harsh field conditions.
