FAQ
Q: Can this module measure multiple signal types simultaneously?
A: The module is designed specifically for 4-20 mA current signals. It can read multiple sensors of this type but not voltage or thermocouple signals without an appropriate converter.
Q: Is the module hot-swappable?
A: No, module replacement requires system power-down to ensure signal integrity and safety.
Q: How does this compare to AAI136 series modules?
A: While both modules provide isolated analog inputs, the AAI136 offers higher channel density and faster sampling rates. The AAI135-S00 focuses on standard 8-channel reliability and high accuracy.
