GE IC200ALG320 Review: 4-Point Analog Output Module
Product Review: GE IC200ALG320 Analog Output Module
The GE IC200ALG320 is a highly capable 4-point analog current output module from the VersaMax I/O series, originally designed by GE Intelligent Platforms and now supported by Emerson Automation. This module delivers four single-ended output channels that generate a 4-20 mA signal with a resolution of 4 µA and an update rate of just 0.3 ms. Engineers rely on this module for precise control in closed-loop and open-loop systems, making it a solid choice for applications involving modulating valves, dampers, VFDs, and signal re-transmission. We find the combination of fast update speed and robust diagnostics particularly valuable for both new installations and legacy upgrades.
Key Features and Technical Specs
The IC200ALG320 offers several standout features based strictly on the provided data. Each output channel provides a 4-20 mA current-sourcing signal with 12-bit analog resolution. The module requires an external power supply of 18-30 VDC or 9.6 to 15 VDC, and consumes a maximum of 240 mA from the backplane. Two LED indicators—FLD PWR for field power and OK for backplane power—offer quick visual status checks. The module also includes diagnostic tools to detect loss of user-side power, and a configurable output default that either holds the last state or scales down to 4 mA upon a CPU fault. Isolation between user input, logic, and frame ground is rated at 250 VAC continuous and 1500 VAC for one minute, ensuring robust protection in industrial environments.
Applications and Practical Value
This module excels in medium to large control systems where distributed I/O reduces long signal runs. Its 4-20 mA outputs suit analog signal-following devices like positioners, single-loop controllers, and data loggers. For signal re-transmission, the IC200ALG320 provides an output representing an internally calculated PLC variable, enabling advanced cascaded control architectures. The fast 0.3 ms update rate supports high-speed applications, while the hold-last-state feature prevents process upsets during communication interruptions. With its proven VersaMax pedigree, this module integrates seamlessly into existing GE or Emerson systems, offering a reliable solution for continuous process control.
Conclusion
For automation engineers and procurement professionals, the GE IC200ALG320 delivers dependable analog output functionality with essential diagnostics and flexible configuration. Its compatibility with the VersaMax platform and Emerson support ensures long-term availability and service. We recommend this module for projects requiring precise 4-20 mA control with minimal downtime risk. For further details or to purchase, visit PLC Source PRO or contact our technical team.
