GE VersaMax IC200ALG262 IC200ALG262G Differential Current input Module

The IC200ALG262 is a differential current input module from the VersaMax I/O platform, designed to interface with analog signal-generating instruments. Manufactured by Emerson Automation, this module is equipped with eight channels to receive standard current input signals (0-20 mA and 4-20 mA).

Key Features:

• Channels: 8 analog input channels supporting single-ended configurations.
• Current Ranges: Configurable for 0-20 mA or 4-20 mA using terminal jumpers.
• Built-in ADC: 15-bit resolution for accurate analog-to-digital conversion.
• Power Supply: Draws power from the backplane; no external power supply required.
• Update Rate: 7.5 ms, allowing for real-time monitoring of input signals.
• Diagnostics: Capable of detecting loss of internal power and open wire faults.

  • 0.5 µA = 1 count (for 4-20 mA)
  • 0.625 µA = 1 count (for 0-20 mA)

Diagnostics and Isolation

• Isolation:
  • Optical isolation between user input and logic.
  • Group to group and channel to channel isolation (250 VAC continuous; 1500 VAC for 1 minute).
• Diagnostics:
  • Loss of user side power and open wire detection for 4-20 mA signals only.

Installation Notes

• Connection Recommendations:
  • Use shielded twisted pair cables for analog channel connections. Grounding should occur at the source device or at the I/O module if grounding at the source is not possible.

Additional Information
