Functional Description

IC200MDL741 is an output module developed by GE. It is part of the VersaMax series. This module features a single group of 16 discrete output points, which can function as either sourcing type outputs or positive logic type outputs. These points are responsible for switching and supplying current to individual loads, ensuring efficient signal output and load control.

Features

  • Positive Logic Outputs: The outputs are sourcing types that supply current to connected loads by switching them to the positive side of the DC power supply.
  • Integrated Protection: Each output is equipped with electronic overcurrent and short circuit protection. Fault conditions such as overcurrent or short circuits generate system alerts, ensuring operational safety and reliability.
  • External Power Requirements: The module requires an external DC power supply to provide energy for switching loads. The external power supply must sustain field power during short circuit events to maintain the module's operating range and prevent misoperations.
  • Intelligent Processing: Data processing is handled by the system�s CPU or Network Interface Unit (NIU). The module processes 16 bits of discrete output data, ensuring high-speed operation and seamless integration with the automation system.

LED Indicators for Status Monitoring

  • Green LEDs: Show the on/off state of each output point. These LEDs rely on field power but remain independent of load conditions.
  • Amber LEDs: Indicate overload conditions on individual output points. Once the overload is cleared, the module resumes normal operation.
  • Green FLD PWR LED: Illuminates when field power is applied.
  • Green OK LED: Signals the presence of backplane power.

External Power Supply Requirements

  • The external power supply powering the module must deliver sufficient field power, even during short circuit events. Short circuits can cause a sudden surge in current demand, and if the power supply is inadequate, the field power may drop below the module's operating range. This voltage drop can result in module misoperation, impacting the system's reliability. Selecting a power supply that can maintain stable voltage under such conditions is essential for uninterrupted functionality.
  • The power supply must be capable of delivering enough short circuit energy without degrading output voltage levels. The energy required depends on the number of output points that might simultaneously short. In scenarios where the power supply cannot meet this demand, incorporating local energy storage solutions like capacitors or batteries can stabilize the system. These devices provide quick bursts of energy, preventing voltage drops and ensuring seamless operation during fault conditions.
  • To enhance the performance of the power supply, minimizing wiring resistance between the power source and the module is crucial. High resistance can lead to voltage drops, affecting the module's performance, especially during high-demand scenarios like short circuits. Using quality conductors and proper wiring practices ensures efficient power delivery, supporting the module's reliability and long-term operation.

Frequently Asked Questions

What is IC200MDL741?
It is an output module developed by GE under VersaMax series.

What power supply is required for the module?
The module requires a 5V power supply for operation, drawing a maximum of 75 milliamps. It also operates at an optimal voltage of 24 volts DC and supports a range of 18 to 30 volts DC for external field power.

What happens if the external power supply is insufficient?
An inadequate external power supply may cause the field power to drop below the specified range during short circuit events, resulting in misoperation of the module. It is essential to ensure the power supply provides sufficient energy, especially for short circuits.

What is the current and voltage rating for the module?
The module supports a resistive load current of 0.5 amps at 30 volts DC. It can handle an inrush current of up to 2.0 amps for 100 milliseconds and maintains a leakage current of 0.5 milliamps.

Can the module handle thermal derating?
Yes, it supports thermal derating, and the number of output points that can be active simultaneously depends on environmental conditions and voltage levels.
