The IC200ALG240 provides eight independent channels of isolated analog current input. Each channel supports a 4–20 mA signal range, making it compatible with the majority of industrial pressure, temperature, and flow transmitters. By utilizing 16-bit resolution, the module captures minute fluctuations in field data, ensuring the PLC CPU receives highly accurate information for PID loops and safety thresholds. This module integrates seamlessly into any VersaMax station, whether connected to a local CPU or a remote Network Interface Unit (NIU).
The IC200ALG240 utilizes advanced channel-to-channel isolation to prevent signal interference in complex electrical environments.

The IC200ALG240 resolves specific industrial pain points through superior electronic design:
Elimination of Ground Loops: Unlike non-isolated modules, the IC200ALG240 features channel-to-channel isolation. This hardware barrier prevents ground loop currents from distorting signal accuracy, even when sensors reside at different ground potentials across large facilities.
High-Fidelity Resolution: The 16-bit architecture provides 65,536 discrete levels of signal interpretation. This capability allows engineers to monitor very fine process variables that 12-bit modules simply cannot detect.
Active Noise Rejection: The integrated 50/60 Hz notch filter automatically strips out electromagnetic interference (EMI) generated by nearby power lines and high-frequency drives. This ensures "clean" data reaching the CPU without requiring extensive software filtering.
Field Power Monitoring: The module continuously monitors the external 24VDC field power supply. If field power drops, the "Field Power" LED alerts technicians immediately, shortening the troubleshooting cycle during system commissioning or maintenance.
We supply the GE Fanuc IC200ALG240 (including the GC revision) in 100% Brand New and Original factory packaging. This hardware remains the current active standard for the VersaMax line. Choosing new-in-box (NIB) modules ensures you receive factory-calibrated components with the latest firmware, avoiding the drift and hardware degradation common in used surplus or "refurbished" units.
Does the IC200ALG240 require a separate terminal base?
Yes, the module installs onto a VersaMax terminal base (such as the IC200TBI001). The base provides the wiring points for the 8 current loops and the external 24VDC field power.
How does the IC200ALG240-GC differ from the standard IC200ALG240?
The "-GC" suffix denotes a specific manufacturing revision. Functionally, it remains 100% interchangeable with earlier versions but includes updated internal components for enhanced reliability and compliance with current industrial standards.
Can I configure individual channels for voltage instead of current?
No, the IC200ALG240 is a dedicated current module (4-20mA). If your application requires voltage inputs (0-10V), you should select a multi-signal module like the IC200ALG264.
What happens if a wire breaks in the 4-20mA loop?
The module detects under-range conditions. Since 4mA is the "live zero," any signal falling significantly below 4mA indicates a broken wire or transmitter failure, which the module reports to the CPU fault table.
