IC697MDL254 48V AC Discrete Input PLC Module GE Fanuc

IC697MDL254 Input Module – AC-Powered Discrete Sensing with High Density

Product Introduction

The IC697MDL254 from GE Fanuc functions as a high-density discrete input module for the Series 90-70 programmable logic controller system. This unit delivers 32 input points, arranged in four isolated groups of eight points each. Each group can connect to a separate phase of an AC power supply, giving you flexibility in three-phase applications. The module operates at a nominal 48V AC and accepts frequencies from 47 to 63 Hz.

This input module works seamlessly with a wide variety of field devices. For instance, you can connect limit switches, pushbuttons, selector switches, and 2-wire or 3-wire electronic proximity switches. The IC697MDL254 features resistive inputs that meet IEC standard current-voltage type 1 characteristics. Consequently, it ensures reliable operation even with devices that have moderate leakage currents.

Key Technical Specifications

The GE Fanuc IC697MDL254 draws only 0.30 A from the 5V backplane bus, making it power-efficient for large I/O racks. Each input point consumes 4.7 mA at rated voltage, which provides sufficient drive current for switching devices. The ON-state input current reaches approximately 10 mA, guaranteeing positive closure detection. Meanwhile, the OFF-state leakage current stays below 2 mA, preventing false triggering.

Configuration of the IC697MDL254 happens entirely through software, so you do not need any DIP switches or jumpers. You set up input references using the MS-DOS configuration function or the Windows-based programming software. Additionally, the module includes mechanical keying. This feature prevents you from inserting an incorrect module type into a specific slot, reducing installation errors.

LED Indicators and Diagnostics

The GE Fanuc IC697MDL254 comes with LED indicators for every input point. These lights show the ON or OFF status clearly on the module faceplate. Therefore, you can quickly verify field device operation without connecting a programming terminal. This visual feedback saves significant troubleshooting time during system startup and maintenance.

Installation and Configuration Guidance

Installing the IC697MDL254 follows a straightforward workflow. First, power down the Series 90-70 rack completely. Next, align the module with your chosen slot and push it firmly until the backplane connector seats properly. Then, secure the unit with the retaining screws. For wiring, connect your AC field devices to the terminal board, respecting the group assignments for phase separation. After restoring power, use your programming software to configure the input references. Finally, test each point by actuating the connected field device and watching the corresponding LED change state.

Frequently Asked Questions (FAQ)

1. What AC voltage does the IC697MDL254 accept?
It accepts 48V AC nominal, with a frequency range of 47–63 Hz. Do not apply DC voltage to this module.

2. Can I use the IC697MDL254 with three-phase systems?
Yes, each of the four groups can connect to a different AC phase, supporting multi-phase applications.

3. How do I know if an input point is active?
Check the built-in LED indicator for that point. A lit LED means the input is in the ON state.

4. Does this module require DIP switches for configuration?
No, all configuration happens through the Series 90-7 programming software. No physical switches exist.

5. What types of switches work with the IC697MDL254?
It works with limit switches, pushbuttons, selector switches, and 2-wire or 3-wire proximity switches.
