More Information

Overview Manuals Scaling Filtering Configuration Application
  • Sixteen single-ended channels provide high-density analog current acquisition
  • Each active channel can use 0-20 mA, 4-20 mA, or 4-20 mA Enhanced scaling
  • The module updates all configured channels within the documented 6-millisecond interval

IC694ALG223 is a General Electric PACSystems RX3i analog input module designed for high-density current-signal acquisition.

The module converts as many as sixteen single-ended field-current channels to controller data with selectable range, channel count, and alarm configuration.

Before installation or replacement, verify the hardware revision, active-channel count, current range, loop power, terminal assignments, scaling, alarms, scan set, and saved RX3i configuration.

Availability, condition, price, and shipping time for IC694ALG223 are confirmed during quotation.

  • Cross-channel rejection is greater than 70 dB from DC to 1 kHz
  • All configured channels are updated within the documented 6 ms interval
  • The active-channel count is selectable from one through sixteen contiguous channels
  • Each active channel can be assigned a supported input-current range
  • Low and high alarm limits and an I/O scan set are included in module configuration
  • Multichannel 4-20 mA process-transmitter acquisition in PACSystems RX3i systems
  • Monitoring of compatible self-powered 0-20 mA industrial current sources
  • High-density analog current measurement for complex machine and process control

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which current ranges can General Electric IC694ALG223 measure?
Each active channel can be configured for 0 to 20 mA, 4 to 20 mA, or 4 to 20 mA Enhanced operation.
How many channels can General Electric IC694ALG223 scan?
The active count is configurable from one through sixteen single-ended channels, scanned in contiguous order.
What does the Enhanced range change on General Electric IC694ALG223?
The 4 to 20 mA Enhanced range reports current below 4 mA as negative data values, allowing the configured logic to distinguish underrange behavior.
Does General Electric IC694ALG223 require external power?
Yes. It uses 120 mA from the 5 V backplane and 65 mA from a 20 to 30 V DC external supply, in addition to the connected loop currents.
Can every General Electric IC694ALG223 revision be hot-swapped?
No. The RX3i system manual states that Revision A does not support hot swap, while Revision BA and later do. Confirm the actual label before planning replacement.
What should be checked when a General Electric IC694ALG223 channel reads incorrectly?
Check loop power, polarity, the 250 Ω input path, terminal assignment, selected range, active-channel count, scaling, alarm limits, and controller data interpretation.
What information should accompany an inquiry for General Electric IC694ALG223?
Provide the complete catalog number, label revision, channel count, signal range per channel, loop-power details, terminal-block information, controller configuration, quantity, and label photographs.
