Description

Overview

The IC694MDL240A is a 16-channel discrete AC input module for the PACSystems RX3i series. Engineered for industrial control applications, it accepts 120 VAC signals from devices such as pushbuttons, limit switches, and proximity sensors. Its robust electrical isolation protects both the module and the system, while integrated LED indicators provide immediate visual status for each input.
