Functional Description

IC200ALG331 is a voltage-current analog output module developed by GE. It is part of the VersaMax series. It is a 4-Channel Isolated 16-Bit Voltage/Current Analog Output Module from the GE Fanuc Versamax Series, designed to provide precise and reliable analog outputs for systems. This module is a versatile component that offers several advanced features to meet the demands of modern control systems.

Features

  • Four Isolated Analog Outputs: The module provides four analog output channels that can be configured for either 4-20mA current or voltage output. Each channel is isolated, which enhances the safety and reliability of the system by preventing interference between channels and reducing the risk of ground loops.
  • High Accuracy and Resolution: This module is factory-calibrated to ensure high accuracy in output signals, with a 16-bit converter resolution. This level of precision makes it suitable for applications requiring fine control over analog outputs, such as in process control systems.
  • Software Configurable: It is fully configurable through software, allowing users to select output types, scaling, and alarm levels for each channel. This flexibility simplifies setup and enables the module to be tailored to specific application requirements.
  • Default and Hold Last State Operation: The module offers a selection between default operation or holding the last known state for each channel in the event of a system failure. Additionally, users can configure default values per channel, which can be useful in maintaining safe operations during unexpected events.
  • Field Recalibration and Diagnostics: It supports field recalibration on command, ensuring that the module remains accurate over time. It also includes diagnostic features such as the selection of under/over range detection and alarm levels, helping to identify and address potential issues before they impact system performance.

Power Requirements

  • The module requires an external 24V power supply to operate the analog outputs. In current mode, a separate power supply is necessary to power the isolated outputs, ensuring the module can deliver the required current to the connected load. This dedicated power source ensures proper operation and prevents any power-related issues during output delivery.
  • On the other hand, for voltage outputs, the power is supplied directly from the module itself, which simplifies the setup and reduces the need for additional external equipment.
  • It is crucial to note that if the module’s power supply is used as a loop supply, the loads connected to the outputs will not be isolated from one another. This lack of isolation could result in potential interference or unwanted interaction between the channels, so proper configuration of power supply and wiring is essential to maintaining the integrity of the system.

Operational Details

  • The module receives four separate words of analog output data from a CPU (Central Processing Unit) or an NIU (Network Interface Unit), which enables seamless integration into a larger control system. This data is processed and used to control the output values for each of the four channels. By receiving distinct output data from the processing unit, the module can manage and adjust its output signals accordingly, ensuring that the overall control system operates smoothly and efficiently.
  • This integration capability allows the module to fit easily into complex industrial systems, making it versatile for a variety of automation and process control applications. The real-time output processing ensures that the system can maintain precise and stable control over the connected devices.

LED Indicators

  • To enhance usability and simplify troubleshooting, the module is equipped with several LED indicators that provide clear visual cues regarding the status of the module’s power supply and operation. These indicators are crucial for monitoring the operational state of the module.
  • The field power LED indicates the presence of power for the analog field-side circuits, while the OK LED shows whether the backplane power is active.
  • If the module is not receiving power either from the field side or the backplane, the corresponding LED will turn off, signaling a power issue. Uniquely, the OK LED on this module is placed before the field power LED in the A slot, which distinguishes it from other models in the VersaMax series. This layout provides a more intuitive way of monitoring the system's power status, simplifying troubleshooting and ensuring that any power issues are easily detected.

Backplane Current

  • The backplane current specifications of the module are designed to support efficient communication and system integration. The module supports a 5V output with a maximum of 10mA or a 3.3V output with a maximum of 115mA. This ensures compatibility with various system configurations and provides the necessary power for communication between the module and the rest of the control system.
  • These current specifications allow the module to be integrated into systems with different power requirements, providing flexibility in system design. It also ensures that the module operates within the necessary power constraints, preventing any overloading or power disruptions within the backplane.

Output Characteristics

  • The module boasts several output characteristics that are essential for its operation in real-time control systems.
  • With an update rate of 7ms maximum, the module ensures that output signals are refreshed quickly enough to meet the demands of high-performance control applications. This fast update rate is critical for systems that require continuous and precise adjustments to output signals in real-time.
