Description
GE Fanuc IC693MDL645 Product Documentation
The
GE Fanuc IC693MDL645 is a high-performance
16-point digital input module designed for GE Fanuc’s 90-30 series PLC systems. It plays a critical role in industrial automation by converting physical switch signals (e.g., pushbuttons, sensors, or limit switches) into digital signals compatible with PLC controllers. The
IC693MDL645 supports
24V DC input and features optical isolation to protect against voltage spikes, making it ideal for harsh industrial environments. With its compact design and plug-and-play compatibility, the
IC693MDL645 simplifies system integration and reduces downtime.

IC693MDL645
- High Reliability: With a MTBF of over 500,000 hours and rugged construction, the IC693MDL645 withstands temperature extremes (-40°C to 70°C) and electrical noise.
- Flexible Configuration: Supports both sinking and sourcing inputs, adapting to diverse sensor types.
- Real-Time Monitoring: LED indicators for each channel provide instant status feedback, minimizing troubleshooting time.
- Space-Saving Design: Compact size (100mm x 120mm x 60mm) optimizes rack space in control panels.
Industries: Manufacturing, energy, water treatment, and automotive.
典型应用场景:
- Factory Automation: Monitoring conveyor belt sensors in a automotive assembly plant.
- 案例: A steel mill used the IC693MDL645 to connect 16 proximity sensors on a rolling line. The module’s noise immunity reduced false signals by 95%, improving production efficiency.
Compared to similar modules, the IC693MDL645 offers:
- Lower Power Consumption: 0.5W per channel (15% less than comparable models).
- Wider Voltage Range: Supports 19.2–30V DC, reducing compatibility issues with aging equipment.
- Integrated Diagnostics: Built-in short-circuit protection eliminates the need for external fuses.

IC693MDL645
- Compatibility: Ensure compatibility with your GE Fanuc 90-30 PLC model (e.g., CPU313, CPU323).
- 环境条件: Choose the module if your site has voltage fluctuations or high EMI/EMC interference.
- 点数需求: For fewer points, consider the IC693MDL630 (8-point version); for more points, use multiple IC693MDL645 modules.
- 接线: Verify wiring polarity to avoid damage from reverse voltage.
- 电压检查: Ensure input voltage stays within 19.2–30V DC to prevent module failure.
- 静电防护: Use antistatic wrist straps during installation to protect against ESD.
