The GE IC200ALG230 is a 12-bit resolution, 4-channel analog input module designed for the GE VersaMax PLC platform. It accepts both voltage and current signals, making it a versatile front-end acquisition module for process control, machine automation, and industrial monitoring applications. This page serves as a comprehensive selection guide for engineers and procurement teams evaluating the IC200ALG230 — including its direct replacements, functional equivalents, and cross-brand alternatives.
Selection Background
Buyers searching for an IC200ALG230 replacement or equivalent analog input module typically face one of three scenarios: the original module is discontinued or on extended lead time; a system upgrade requires a higher-performance substitute; or a cross-brand migration is underway. Understanding which alternative is truly compatible — and under what conditions — is critical to avoiding costly downtime. This guide uses verified technical data to help you make that decision with confidence.

Selection Guide
Answer these three questions to confirm the IC200ALG230 — or its equivalent — is the right choice for your application:
- Is your existing PLC platform GE VersaMax? If yes, the IC200ALG230 or its direct revisions (230E/230F) are the safest choice. If no, a cross-brand alternative with gateway integration may be required — contact Konmask for a compatibility assessment.
- Do your sensors output 4–20 mA or 0–10 VDC signals? The IC200ALG230 natively supports both. If your application requires thermocouple or RTD inputs, consider the IC200ALG620 or IC200ALG630 instead.
- Is 12-bit resolution sufficient for your process? For standard industrial process control, 12-bit (4,096 counts) is adequate. For high-precision metrology or laboratory applications, evaluate the IC200ALG260 (15-bit) or a higher-resolution cross-brand module.

Replacement & Compatibility FAQ
Q: Can the IC200ALG230E directly replace the IC200ALG230 without any configuration changes?
A: Yes. The IC200ALG230E is a direct drop-in replacement for the IC200ALG230. It uses the same I/O register mapping, identical signal ranges, and the same physical form factor. No changes to Proficy Machine Edition logic or hardware configuration are required.
Q: Is the IC200ALG260 a compatible equivalent to the IC200ALG230?
A: The IC200ALG260 is a functional equivalent with higher 15-bit resolution. It is compatible with the same VersaMax platform and accepts the same voltage/current signal types. However, the scaling registers differ, so analog scaling blocks in your PLC program must be updated to reflect the new resolution range.
Q: Can a Siemens SM331 or Allen-Bradley 1756-IF8 substitute for the IC200ALG230 in an existing VersaMax system?
A: These modules are not direct substitutes — they belong to different PLC platforms and cannot be installed in a VersaMax carrier base. They are listed as cross-brand alternatives for engineers planning a full platform migration. If you need a substitute that works within your existing VersaMax system, the IC200ALG230E or IC200ALG260 are the correct choices. Contact Konmask for migration planning support.
