GE Fanuc IC697MDL671 Discrete Input Module 24V DC 16 Point

Product Overview

The GE Fanuc IC697MDL671 is a high-performance 16-point discrete input module designed for the Series 90-70 PLC system. Engineered for maximum flexibility, this module features four isolated groups of four inputs, allowing it to interface with a wide range of field devices. The IC697MDL671 is specifically optimized for dynamic industrial applications, offering 14 high-speed interrupt points that ensure rapid response times and deterministic control under heavy processing loads.

Technical Configuration

Versatile architecture for advanced sensor and logic integration:

• Input Density: 16 Points (4 Isolated groups of 4)
• Logic Support: Compatible with both Positive and Negative logic devices
• Interrupt Capacity: 14 Interrupt points + 2 Configuration points
• Signal Filtering: Software-configurable input filters (1 ms or 10 ms)
• Sensor Compatibility: Fully compatible with industrial proximity switches
• Bus Efficiency: Low current draw of only 0.30 Amps from the 5V backplane

Technical Specifications

Engineering Advantages

The IC697MDL671 stands out for its robust electrical protection, providing 1500V isolation between inputs and the backplane, and 500V isolation between internal groups to prevent ground loop interference. Its high-speed interrupt performance allows all 14 interrupts to run at maximum rates, making it ideal for event-driven logic and time-critical sensing. Additionally, the configurable delay options (1ms/10ms) allow engineers to precisely tune signal processing to filter out industrial electrical noise while maintaining high-speed accuracy.

Technical FAQs

Q1: What is the benefit of the isolated group structure?
A1: The 4x4 isolated group design allows you to use different power sources or common references for each group, providing significant flexibility when mixing different field device types on a single module.

Q2: How do I choose between the 1ms and 10ms filter settings?
A2: Use the 1ms setting for high-speed tracking and interrupts. Use the 10ms setting for standard pushbuttons or sensors in environments with high electromagnetic interference (EMI) to prevent false triggering.

Q3: Does this module support both sinking and sourcing inputs?
A3: Yes, its positive and negative logic compatibility means it can be wired to accommodate either sinking or sourcing field devices depending on your common-line configuration.
