Compatible Replacement & Equivalent Models
If the GE SD30B is discontinued, on long lead time, or outside budget, the following models may serve as functional equivalents or drop-in replacements depending on your system configuration:
- GE IC693MDL940 – Digital Output Module, Series 90-30, similar I/O count
- GE IC694MDL940 – PACSystems RX3i compatible digital output
- GE IC693MDL753 – Discrete output module, compatible backplane
- Emerson PACSystems RX3i equivalents – Post-acquisition GE Vernova lineup
- Third-party equivalents: Siemens S7-300 SM322, Allen-Bradley 1756-OB16 (requires I/O mapping adaptation)
⚠ Important: Confirm backplane compatibility, firmware version, and I/O addressing before substituting any module. Contact support@konmask.com for a free compatibility check.

System Compatibility
The GE SD30B is designed for use within the following GE control system platforms:
- GE Series 90-30 (IC693 family) — primary platform
- GE PACSystems RX3i (IC694/IC695 family) — with adapter or compatible rack
- GE Series 90-70 — verify rack and power supply compatibility
- GE Proficy Machine Edition — programming and configuration software
Not compatible with: Siemens S7 racks, Allen-Bradley ControlLogix racks, or Mitsubishi MELSEC racks without hardware adaptation.
Selection Guide
Use the following criteria to determine whether the GE SD30B is the right module for your application:
- Step 1 — Identify your rack: Confirm your existing GE rack model (IC693CHS, IC694CHS, etc.)
- Step 2 — Check I/O requirements: Match output channel count and voltage rating to your field devices
- Step 3 — Verify firmware: Ensure CPU firmware supports the SD30B module revision
- Step 4 — Assess lead time: If OEM lead time is long, evaluate certified refurbished or equivalent alternatives
- Step 5 — Confirm certifications: Verify CE/UL compliance for your regional regulatory requirements
