Description
GE IC693MDL655 Technical Specifications:
- Input Type: 24 VDC Positive Logic (Sourcing).
- Number of Points: 32 points.
- Input Voltage Range: 15 to 30 VDC.
- Input Current: 5 mA nominal at 24 .
- ON/OFF Thresholds: 12 VDC minimum ON, 5 VDC maximum OFF.
- Response Time: 1 ms maximum.
Functional Features:
- High Density: 32 inputs in a single module slot, maximizing backplane utilization.
- Status Indication: Individual LEDs for all 32 channels.
- Optical Isolation: Full channel-to-bus isolation for enhanced system reliability.
- CE Approved: Meets international safety and electromagnetic compatibility standards.
Application Scenarios:
- Large-scale material handling and sorting systems.
- Packaging machines with numerous sensor inputs.
- Any application requiring maximum I/O density in a Series 90-30 rack.
Material Composition & Structural Characteristics:
- Design: High-density SMT (Surface Mount Technology) PCB.
- Connectors: Standard Series 90-30 front terminal block.
- Indicators: Dual rows of 16 status LEDs.
Working Principle: Operates identically to the 16-point MDL645 but processes 32 independent input channels simultaneously. The high-density design utilizes advanced multiplexing and compact optocoupler arrays to maintain fast response times while doubling the channel count.
Installation Requirements:
- Space: Requires only one slot but demands careful cable management due to 32 field wires.
- Power: Ensure the 24 VDC supply can handle the cumulative current of up to 32 inputs (approx. 160 mA total).
- Wiring: Use high-density terminal blocks or pre-wired cable assemblies for efficient installation.
Usage Precautions:
- Heat Dissipation: With 32 active inputs, the module generates more heat; ensure adequate cabinet airflow.
- Load Capacity: Do not use this module to source power to field devices; it is strictly a signal input module.
- Fault Finding: Utilize the PLC software’s force table and diagnostic tools to quickly identify faulty sensors among the 32 points.
