FAQ

Q: What is the main difference between TERT4A, TERT8A, and TERT16A?
A: The difference lies in the number of channels and terminal configuration. TERT4A has 4 points, TERT8A has 8 points, and TERT16A has 16 points. Terminal types can be M4 screws or spring-clamp depending on the model.

Q: Can TERT*A be used in high-noise industrial environments?
A: Yes. The board features high-grade insulation and channel isolation to minimize electrical noise interference.

Q: Is TERT*A compatible with Yokogawa I/O cards?
A: Yes. Fully compatible with CENTUM VP/CS, ProSafe-RS I/O modules, and system node units.
