Selection Guide
Use the following criteria to confirm the HE693THM409 is the right module for your application:
- Signal Type: Do you need thermocouple (J/K/T/E/R/S/B) or mV input? → HE693THM409 ✓
- Channel Count: Do you need 4 isolated analog input channels? → HE693THM409 ✓
- Platform: Are you using a GE Series 90-30 rack? → HE693THM409 ✓
- Need 8 channels? → Consider HE693THM410 (8-channel variant)
- Need voltage/current (0–10V / 4–20mA) input instead? → Consider IC693ALG221 or IC693ALG222
- Replacing a failed module? → Verify the existing module label and firmware; contact Konmask for cross-reference support

Replacement & Compatibility FAQ
Q: Can the HE693THM409 replace the IC693TCM302?
A: Yes, the IC693TCM302 is a functionally equivalent GE Fanuc thermocouple input module for the Series 90-30 platform. Verify channel count and configuration parameters in your PLC program before swapping.
Q: Is the HE693THM409 compatible with GE Series 90-70?
A: No. The HE693THM409 is designed exclusively for the Series 90-30 backplane. For Series 90-70, refer to IC697 series analog input modules.
Q: Can I use a Siemens S7-300 thermocouple module as a replacement?
A: Not directly. Cross-brand replacement requires a different rack, power supply, and PLC program. It is only feasible during a full system migration project.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. CoC and test reports are available upon request for all orders.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 2–4 weeks. Contact us for real-time availability.
