Compatible Replacement & Equivalent Models
When the IC693ALG223 is discontinued, obsolete, or unavailable, the following models are commonly evaluated as replacements. Always verify firmware compatibility and I/O mapping before substitution.
- IC693ALG221 — GE Series 90-30, 8-ch analog voltage input; half the channel count, same bus interface. Suitable when fewer channels are needed.
- IC693ALG222 — GE Series 90-30, 16-ch analog current input (4–20 mA); use when field devices output current signals instead of voltage.
- IC693ALG390 — GE Series 90-30, 4-ch analog combo (input/output); suitable for mixed I/O applications with reduced channel requirements.
- IC694ALG223 — GE Series 90-30E (enhanced backplane); functionally equivalent with improved diagnostics. Drop-in replacement for upgraded racks.
- Third-party equivalents — Modules from Horner, Spectrum Controls, or ProSoft may offer Series 90-30 bus compatibility; confirm via vendor datasheets.

Selection Guide
Use the decision criteria below to confirm IC693ALG223 is the correct module for your application:
- ✅ Platform: Your rack is Series 90-30 (IC693 backplane) — confirmed compatible
- ✅ Signal type: Field devices output voltage (±10 V or 0–10 V) — confirmed compatible. If 4–20 mA current, select IC693ALG222 instead.
- ✅ Channel count: You need up to 16 analog voltage inputs on a single module — confirmed compatible. For 8 channels, IC693ALG221 is more cost-effective.
- ✅ Resolution: 12-bit (4,096 counts) is sufficient for your process — confirmed compatible. For 16-bit resolution, consider PACSystems RX3i platform migration.
- ⚠️ Isolation requirement: IC693ALG223 is non-isolated. If galvanic isolation is required between channels, evaluate isolated analog modules or external signal conditioners.

Replacement & Compatibility FAQ
Q: Can IC693ALG223 replace IC693ALG221?
A: Yes, with caveats. The ALG223 has 16 channels vs. 8 on the ALG221. The I/O reference table addresses will differ — update your CPU configuration and ladder logic accordingly.
Q: Is IC693ALG223 compatible with PACSystems RX3i?
A: No. The IC693 series uses a different backplane bus than the IC695 (RX3i) platform. They are not interchangeable.
Q: Can I use IC694ALG223 as a drop-in replacement?
A: Generally yes, if your rack supports the IC694 (enhanced Series 90-30) backplane. Verify rack revision compatibility before installation.
Q: What is the difference between IC693ALG223 and IC693ALG222?
A: The ALG223 accepts voltage inputs (±10 V / 0–10 V); the ALG222 accepts current inputs (4–20 mA / 0–20 mA). They are not interchangeable without changing field wiring.
Q: Do you provide a certificate of conformance?
A: Yes, available upon request for all new and refurbished units.
