What Is the IC693MDL655?
Struggling with high-density input requirements in your industrial control system? The GE IC693MDL655 offers a robust solution. This discrete input module, part of the Series 90-30 platform by GE Fanuc (now Emerson Automation), provides Thirty-Two (32) input channels at 24 VDC nominal voltage. It supports both Positive and Negative logic wiring configurations, giving you flexibility in sensor integration. With an input voltage range of 0-30 VDC and an input current of 7 mA per channel, it handles a variety of on/off devices like limit switches, proximity switches, and pushbuttons. The module draws 195 mA @ 5VDC and 224 mA @ 24VDC from the backplane. Its response time is 2 ms on and 2 ms off, ensuring quick signal processing. Please note that this product has a lifecycle status of Discontinued/Obsolete; verify availability with SpareTechPLC before ordering.
Technical Specifications Breakdown
Understanding key parameters helps you match this module to your application. The IC693MDL655 features Thirty-Two (32) input points grouped into Four (4) groups, with Eight (8) inputs per group. This grouping simplifies wiring and diagnostics. The input voltage range spans 0-30 VDC, with a nominal input voltage of 24 VDC. The trigger voltage is 11.5-30 Volts, meaning the module reliably detects on-state signals within that band. Off-state voltage is 0-5 VDC, ensuring clear distinction between logic levels. On-state current is 3.2 mA, while off-state current is 1.1 mA. The on response time is 2 ms typical and maximum, providing consistent performance for fast-switching applications. These specs make the module suitable for environments requiring high channel counts and reliable DC sensing.
Industry Applications
In manufacturing lines, the IC693MDL655 excels at monitoring limit switches and proximity sensors on conveyor systems. Its 32 input points allow dense packing of sensor feedback, reducing the number of modules needed. For example, in a bottling plant, each group of eight inputs can monitor a section of the line, simplifying troubleshooting. The positive/negative logic wiring accommodates both sourcing and sinking sensors, common in mixed-vendor installations. The 2 ms response time ensures rapid detection of part presence or jams, supporting high throughput. This module also works well in material handling applications where pushbuttons and auxiliary contacts provide operator inputs.
Installation & Setup Guidance
Mount the IC693MDL655 into any available I/O slot on a Series 90-30 baseplate—whether CPU, I/O expansion, or remote I/O baseplate. It occupies a single slot on 5-slot or 10-slot baseplates. The module uses two male 24-pin connectors (Fujitsu FCN-365P024-AU) on the front panel for input wiring. Use pre-wired cables such as IC693CBL327 or IC693CBL328, or custom-build cables as needed. Connect input devices like proximity sensors or pushbuttons to the appropriate pins for groups A, B, C, and D. Ensure wiring matches your chosen logic configuration (positive or negative). The module's LED indicators (A1-A8, B1-B8, C1-C8, D1-D8) provide visual status for each input group, aiding initial setup and ongoing diagnostics.
Maintenance & Reliability
Regular inspection of the IC693MDL655 ensures long-term reliability. Check LED indicators periodically to verify input status; any unexpected patterns may indicate wiring issues or sensor faults. The module uses optocouplers for backplane isolation (1500 Volts between field and logic sides), protecting the PLC from field-side transients. Keep the module free from dust and moisture, as contaminants can affect connector integrity. Since the product is discontinued/obsolete, consider stocking spare modules to avoid downtime. For replacement options, contact SpareTechPLC to discuss compatible alternatives.
Compatibility & Integration
The IC693MDL655 integrates seamlessly with Series 90-30 PLCs, including embedded and modular CPUs. It works with CPU baseplates, I/O expansion baseplates, and remote I/O baseplates. The module's 32-point density and 24 VDC input range make it compatible with a wide range of industrial sensors and switches. No special communication protocols are required—it connects directly to the backplane. For wiring, use the specified pre-wired cables or custom assemblies. Always verify compatibility with your specific CPU model and baseplate configuration before installation.
Selection Guide & Purchasing Advice
Before purchasing the IC693MDL655, confirm your system's backplane current capacity: the module draws 195 mA @ 5VDC and 224 mA @ 24VDC. Ensure your baseplate has an available I/O slot and that your power supply can handle the additional load. Since this module is discontinued/obsolete, verify current stock and lifecycle status with SpareTechPLC. SpareTechPLC offers reliable sourcing for legacy GE Fanuc parts, helping you maintain existing systems without costly upgrades. Consider ordering compatible cables (IC693CBL327 or IC693CBL328) at the same time to ensure a complete setup.
