FAQ
-
Can the input range / the AAV144-S00/A4S00 be configured for ranges other than ±10V?
No, this module is specifically designed for ±10V DC input; for other ranges, different modules must be used. -
Is each channel individually isolated from others and from the system bus?
Yes, each input channel is galvanically isolated to prevent signal crosstalk and ensure safety. -
What is the resolution / the analog-to-digital converter?
The module uses a 16-bit A/D converter, providing high-resolution voltage measurements. -
Does the module support signal diagnostic features such as wire break detection?
Yes, it includes open wire detection and abnormal signal diagnostics. -
Can the AAV144-S00/A4S00 module operate in redundant configurations?
Yes, it supports redundancy in compatible Yokogawa control systems. -
What is the default channel sampling time?
The conversion time is approximately 50 milliseconds per channel. -
Does this module support remote calibration?
Yes, calibration and configuration can be performed through Yokogawa’s engineering tools. -
What is the typical input impedance for each channel?
