Comparison with Similar Modules

• The AAI835-S50 supports both input and output channels in a single module, unlike some Yokogawa modules that only offer input or output.

• Fully isolated channels reduce interference and improve measurement accuracy compared with non-isolated models.

FAQ
Q: Can this module handle signals outside the 4-20 mA range?
A: No, the AAI835-S50 is specifically designed for standard 4-20 mA analog signals.

Q: Is it compatible with explosion-proof installations?
A: The current model (S50) has no explosion protection; consult Yokogawa’s EX-certified modules for hazardous environments.
