Product Overview

The GE IC694MDL645 is a 16-point discrete input module engineered for high-density signal acquisition within the PACSystems™ RX3i platform. This module is designed to interface with a wide range of 24 VDC field devices, providing a critical link between industrial hardware and the PLC processor. A key feature of the IC694MDL645 is its internal circuitry, which supports both positive and negative logic (sink or source) configurations, offering maximum flexibility during control cabinet wiring. Its compact architecture allows for seamless integration in both local RX3i backplanes and remote I/O stations, ensuring reliable data feedback for automated processes.

Key Hardware Parameters

• Input Points: 16 channels organized in a single group with a common return.

• Operating Voltage: 24 VDC nominal, with an absolute range of 0 to 30 VDC.

• Logic Compatibility: Supports both Sink and Source wiring configurations.

• Input Thresholds: ON-state requires 11.5 VDC to 30 VDC; OFF-state is defined as 0 VDC to 5 VDC.

• Current Consumption: Typically draws 80 mA from the 5V backplane bus.

• Input Impedance: Designed with a 3.2 mA minimum ON-state current to ensure signal stability.

• Response Time: 7ms typical (input filter) for reliable noise rejection in industrial environments.

• Isolation Integrity: Rated for 1500 VAC (1 minute) between the field-side inputs and the logic-side backplane.

• Visual Indicators: 16 independent green LEDs located at the top of the module for real-time status monitoring.

• Physical Profile: Weight: 0.3 kg; Dimensions: 3.5 x 13.2 x 13.5 cm.

Industrial Applications

The IC694MDL645 is a workhorse component in diverse automation sectors. In High-Speed Manufacturing, it is used to track the status of limit switches, optical sensors, and emergency stop buttons across assembly lines. For Material Handling systems, it monitors pallet detection and conveyor gate positions to ensure synchronized movement. Within Energy and Infrastructure projects, this module provides the ruggedness needed to interface with field-mounted pressure switches and flow meters. Its compatibility with the RX3i series makes it a go-to solution for system integrators looking to upgrade legacy GE 90-30 systems to modern PACSystems technology while maintaining reliable 24V discrete signaling.
