Description
GE IC200MDD842B Technical Specifications:
- Inputs: 16 points, grouped in two banks of 8.
- Input Voltage: 24VDC positive logic.
- Input Current: Typically 5mA per point.
- Isolation: 500V isolation between input groups and backplane.
Functional Features:
- High Density: 16 inputs in a single module slot.
- LED Indicators: Individual LEDs for each input point for easy field troubleshooting.
- Filtering: Configurable input filters to reject noise and contact bounce.
Application Scenarios:
- Machine safety interlock monitoring.
- Limit switch and proximity sensor input.
- Status monitoring of motor starters and valves.
Material Composition & Structural Characteristics:
- Terminals: Removable terminal blocks for fast wiring.
- Protection: Reverse polarity protection and overvoltage clamping on input circuits.
Working Principle: The module conditions incoming 24VDC signals through opto-isolators, converting them to logic-level signals that are read by the CPU during the input scan phase.
Installation Requirements:
- Wiring: Use 18-22 AWG wire for terminal connections.
- Common: Ensure the 24VDC common is properly connected to the module’s COM terminal.
Usage Precautions:
- Voltage Limits: Do not exceed 30VDC on input terminals to prevent damage.
- Grounding: Ground the shield of input cables at the panel entry point only.
