Product Overview

The GE IC693ALG223C is a high-density analog current input module for the Series 90-30 PLC platform. It provides 16 single-ended channels for reading 4–20 mA signals from field transmitters, enabling accurate process monitoring in industrial control applications. Designed for precision and reliability, this module supports stable data acquisition in demanding environments. We supply this unit as 100% brand new, original factory condition to ensure consistent performance and long service life.

Technical Specifications

Engineering Advantages

High-Density Signal Processing
16-channel design in a single slot maximizes I/O density, reducing rack space and overall system cost.

Rapid Data Refresh
13 ms update cycle ensures fast, synchronized data acquisition across all channels for stable process control.

Precision Current Monitoring
12-bit resolution (4 µA per count) enables fine-grained detection of process variations in analog loops.

Robust Noise Rejection
Built-in filtering reduces EMI effects, ensuring stable and accurate readings in electrically noisy environments.

FAQs

Does the IC693ALG223C require an external power supply?
Yes. While the module is powered by the backplane, the 4–20 mA loops require an external 24 VDC supply for field devices.

How does it detect a broken wire?
A drop toward 0 mA is detected as an under-range condition, triggering a diagnostic fault bit in the PLC.

Can it handle 0–20 mA signals?
It is optimized for 4–20 mA. 0–20 mA can be used with appropriate scaling in the PLC program.

What does the “C” revision mean?
It indicates a hardware revision with improved internal components while maintaining full backward compatibility with Series 90-30 systems.
