Description
IC693MDL740 Product Specification
1. Product Description
TheIC693MDL740is a high-performance digital input module designed by GE Fanuc for its 90-30 Series PLCs. This module is widely used in industrial automation systems to convert discrete switch signals (e.g., pushbuttons, limit switches, and sensors) into digital data compatible with PLC controllers. The IC693MDL740 features 16 isolated input channels, the ability to handle voltages from 10–30 VDC, and robust surge protection, making it ideal for harsh industrial environments. By integrating the IC693MDL740 into automation setups, users can achieve reliable signal acquisition, reduce downtime, and optimize system efficiency.

3. Advantages and Features
- High Reliability: The IC693MDL740 incorporates optical isolation for each channel, protecting the PLC from voltage spikes and ground loops. This design ensures a MTBF of over 500,000 hours in industrial settings.
- Wide Voltage Tolerance: Supports 10–30 VDC inputs, eliminating the need for precise voltage regulation and reducing installation costs.
- Flexible Configuration: Adjustable response times (1–20 ms) allow users to filter out noise or capture fast signals based on application needs.
- Space-Saving Design: Compact size (100 mm × 80 mm × 60 mm) fits into tight control panels without compromising performance.
4. Application Areas and Use Cases
Industry Applications:
- Manufacturing (assembly lines, robotics)
- Energy (power plants, renewable energy systems)
- Water and wastewater treatment
- Oil and gas (pump stations, valves)
Case Study:
A chemical plant in Germany upgraded its legacy control system with the IC693MDL740 to monitor 100+ pressure switches and temperature sensors. The module’s surge protection and wide voltage range reduced signal errors by 95%, leading to a 20% reduction in maintenance costs over two years.

6. Selection Recommendations
- Compatibility: Ensure your PLC is part of the GE Fanuc 90-30 Series (e.g., IC693CPU311, IC693CPU321).
- Voltage Requirements: Match the input voltage (10–30 VDC) with your field devices.
- Channel Count: If 16 channels are insufficient, consider the IC693MDL750 (32 channels).
- Environment: For explosive atmospheres, pair the module with GE Fanuc’s intrinsically safe barriers.
7. Precautions
- Wiring: Use twisted-pair cables for signal lines to minimize EMI interference.
- Voltage Check: Verify input voltage before powering the module to avoid damage.
- Grounding: Connect the module’s chassis ground to the system ground for optimal isolation.
- Firmware: Update firmware regularly via Proficy Machine Edition to access the latest features.
