GE IC694MDL660CA-BC Digital Input Module

Overview

The GE IC694MDL660CA-BC is a 32-point 24VDC digital input module for PACSystems RX3i. It delivers high-density signal acquisition with fast response and flexible logic selection. The module supports both positive and negative logic configurations. Inputs are divided into four isolated groups of eight, each with a separate common terminal. This design improves noise immunity and enables flexible wiring. The module efficiently captures high-speed digital signals from sensors, switches, and contact closures. It is ideal for industrial automation systems requiring reliable and rapid input processing.
