Product Overview
The IC693ALG221J is a 4-channel analog current input module for the GE Fanuc Series 90-30 PLC system. It converts standard 4–20 mA process signals from field transmitters into digital values for the CPU. This makes it ideal for monitoring continuous industrial variables such as pressure, flow, and temperature. The module is supplied as 100% brand new and original, ensuring accurate and stable performance in process control applications.

Engineering Advantages
High-Precision Signal Conversion
12-bit resolution provides fine measurement granularity, enabling accurate monitoring of critical process variables and stable control loop performance.
Strong Electrical Isolation
1500 V isolation protects the PLC backplane from ground loops, surges, and industrial electrical noise, improving system reliability.
Fast Data Acquisition
With an update rate of approximately 1.5 ms per channel, the module supports responsive PID control and rapid fault detection.
Loop Fault Detection
The 4–20 mA standard allows detection of open-circuit conditions when current drops below 4 mA, enabling immediate fault signaling.
FAQs
Does it support voltage inputs like 0–10 V?
No. It is designed specifically for 4–20 mA current loops. Voltage input modules such as IC693ALG220 or IC693ALG222 should be used instead.
What does the “J” revision mean?
It indicates the latest hardware revision and is fully backward compatible with earlier IC693ALG221 versions.
Can it be used with both 2-wire and 4-wire transmitters?
Yes. It supports both loop-powered (2-wire) and externally powered (4-wire) transmitters when wired correctly.
Is the unit factory sealed?
Yes. The IC693ALG221J is supplied as 100% brand new, original equipment in factory-sealed packaging.
