GE Fanuc IC697MDL652 Input Module 32 Points

IC697MDL652 Input Module – Flexible and High-Density Sensing

Product Introduction

The IC697MDL652 from GE Fanuc is a versatile discrete input module designed for the Series 90-70 programmable logic controller platform. It accommodates 32 input points, arranged in four isolated groups of eight. This module supports both positive and negative logic, giving you greater flexibility when connecting various field devices. For example, it works seamlessly with proximity sensors, limit switches, selector switches, and pushbuttons. Its nominal operating voltage is 12V DC, with a wide input range from -2.5 to 15V DC.

Furthermore, the IC697MDL652 includes a selectable input filter option. You can choose between 1 ms and 10 ms response times, depending on your application’s noise immunity and speed requirements. This feature is particularly useful in environments with electrical interference. Additionally, the module provides a dedicated interrupt input, which enables fast event-triggered processing without scanning delays.

Key Technical Specifications

The GE Fanuc IC697MDL652 draws only 0.3 A from the backplane, making it power-efficient for large I/O configurations. Each input point has a typical impedance of 1.12 kΩ, which ensures consistent performance across the operating range. The ON-state voltage spans 7.5 to 15V DC, while the OFF-state voltage is between 0 and 2.5V DC. Correspondingly, the ON-state current ranges from 6 to 15 mA, and the OFF-state current stays below 2.5 mA. This clear threshold separation prevents false triggering and enhances reliability.

Isolation is another strength of this module. The IC697MDL652 offers 1500V isolation between the backplane and inputs, plus 500V between input groups. This design protects the CPU and backplane from field wiring faults. Moreover, the module complies with VME bus standard C.1, ensuring compatibility with all Series 90-70 racks and CPUs.

Mechanical and Environmental Ratings

The IC697MDL652 is constructed for long-term service in demanding industrial settings. It operates reliably within a broad temperature range and withstands vibration and humidity typical of factory floors. LED indicators on the faceplate provide clear status for each input point, simplifying diagnostics and troubleshooting. The module’s standard size fits any Series 90-70 slot, allowing flexible system layouts.

Installation and Configuration Guidance

Installing the IC697MDL652 is a quick and straightforward task. Begin by powering down the PLC rack. Next, align the module with the chosen slot and push it in until the backplane connector is fully seated. Then, fasten the retaining screws to secure the module. For wiring, connect your field devices to the terminal board following the group assignments. After powering up, configure the input filter setting in your programming software—select 1 ms for fast response or 10 ms for noise rejection. Finally, test each input point to verify proper operation. For optimal noise immunity, use shielded cables for long sensor runs and ground the shield at one end only.

Frequently Asked Questions (FAQ)

1. What is the difference between positive and negative logic on the IC697MDL652?
Positive logic means the input is ON when voltage is present; negative logic means ON when the input is grounded. You can configure each group accordingly.

2. How do I select the input filter time on this module?
You set the filter time via your Series 90-7 programming software. Choose 1 ms for high-speed applications or 10 ms for noisy environments.

3. Can the IC697MDL652 accept signals from 24V DC sensors?
No, its rated voltage is 12V DC with a maximum of 15V DC. Using 24V sensors may damage the module.

4. What is the purpose of the interrupt input?
The interrupt input allows the module to trigger an immediate CPU response, bypassing the normal scan cycle for time-critical events.

5. Is the IC697MDL652 compatible with all Series 90-70 CPUs?
Yes, it works with all CPUs in the Series 90-70 family that support VME standard C.1 revision.
