Product Overview

The 100% Brand New GE IC200ALG320 delivers four independent 4-20mA analog output channels for the VersaMax I/O system. It converts digital values from the CPU into precise current signals for field devices like control valves, variable speed drives, and positioners. The module features 12-bit resolution and a fast 0.3ms update rate.

Engineering Advantages

•  

  Rapid Control Response: The 0.3ms update rate ensures immediate execution of CPU commands. This minimizes dead time in fast-acting closed-loop control systems (e.g., flow or pressure control).

   

•  

  Independent Channel Operation: Each channel operates independently with its own Digital-to-Analog Converter (DAC). A fault on one output does not affect the operation of the remaining three channels.

   

•  

  Live Replacement (RIUP): The module supports Removal and Insertion Under Power. Technicians replace a faulty unit without shutting down the process, maintaining continuous operation.

   

•  

  Visual Diagnostics: Dual LEDs confirm power integrity. The "FLD PWR" LED verifies external field power, while the "OK" LED confirms backplane logic power, simplifying troubleshooting.

   

FAQs

•  

  Does this module require an external power supply?

  Yes. The module requires an external 18-30 VDC power supply to drive the 4-20mA loops. It does not source power from the backplane for the field outputs.

   

•  

  Can I use 0-20mA or 0-10V output ranges?

  No. The IC200ALG320 is factory-configured for 4-20mA current output only. It does not support voltage output or 0-20mA ranges.

   

•  

  What terminal base is required?

  It mounts on standard VersaMax terminal bases (e.g., IC200TBM002 or IC200TBS002). Ensure the terminal base connects to the external 24VDC supply.

   

•  

  Is the output isolated?

  Yes. The module provides 250 VAC isolation between the field wiring (outputs) and the backplane logic. However, the four output channels share a common return (COM).
