Description
GE IC693MDL655K 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.
- Response Time: 1 ms maximum.
- Backplane Compatibility: Standard Series 90-30 and PACSystems RX3i (with appropriate backplane).
Functional Features:
- Direct Replacement: Pin-for-pin and functionally identical to the IC693MDL655.
- High-Density I/O: 32 channels per slot.
- Diagnostic LEDs: Individual channel status indicators.
- Robust Design: Industrial-grade isolation and transient protection.
Application Scenarios:
- Direct replacement for existing IC693MDL655 modules during maintenance.
- New installations requiring 32-point 24 VDC sinking inputs.
- System expansions where rack space is at a premium.
Material Composition & Structural Characteristics:
- Hardware Revision: May feature updated internal components or revised PCB layout compared to the original MDL655.
- Enclosure: Standard Series 90-30 plastic housing.
- Labeling: Clearly marked with the “K” revision for inventory and compatibility tracking.
Working Principle: Functions exactly as the IC693MDL655, converting 24 VDC positive logic field signals into digital data for the PLC CPU via optical isolation and internal buffering.
Installation Requirements:
- Interchangeability: Can be directly swapped with IC693MDL655 modules without software or hardware modifications.
- Wiring: Standard 32-point wiring practices apply.
- Configuration: No special configuration required; the PLC automatically recognizes the module type.
Usage Precautions:
- Mixing Revisions: While generally compatible, avoid mixing different hardware revisions in redundant I/O configurations unless verified by GE documentation.
- Sourcing: As a discontinued product, ensure procurement from reputable suppliers to guarantee authenticity.
- ESD: Standard ESD precautions apply during installation and replacement.
