Frequently Asked Questions
Q: Can this module be used in non-CENTUM Yokogawa systems?
A: No. The ASI133-H00/ATSA3S is specifically designed for CENTUM CS and CENTUM VP platforms and is not compatible with other Yokogawa control systems.
Q: Does this module support digital input signals?
A: No. This model is strictly an analog input module and does not process digital or discrete signals.
Q: Are special considerations required for installation?
A: Yes. Proper grounding, shielding, and correct signal range matching are essential to maintain measurement accuracy and avoid electrical noise.
