Application-Specific FAQ
Q: Can the IC670ALG630 mix different thermocouple types across its 8 channels?
A: Yes. Each channel is independently configurable for TC type (J, K, T, E, R, S, B, or C) via software, allowing mixed-sensor installations on a single module.
Q: Is cold junction compensation automatic or does it require external hardware?
A: The IC670ALG630 includes an internal cold junction compensation sensor. No external reference junction or isothermal terminal block is required.
Q: What PLC controllers are compatible with this module?
A: The module is compatible with GE Series 90-30, Series 90-70, VersaMax, and PACSystems controllers via the Field Control bus interface units (GBI or PBI).
Q: What happens if a thermocouple wire breaks during operation?
A: The module’s per-channel open-wire detection immediately flags the fault in the controller’s I/O status table, allowing the control program to execute a safe fallback routine without affecting other channels.
Q: Can this module be used in hazardous area (Ex) installations?
A: The IC670ALG630 itself is not ATEX/IECEx rated. For hazardous area use, install the module in a purged/pressurized enclosure or use certified Zener barriers on the field wiring side.
Q: Do you supply the IC670ALG630 with a warranty?
A: Yes. Konmask.com provides a 90-day quality guarantee covering manufacturing defects and functional failures. Extended warranty options are available upon request.
