What thermocouple types does the AAV141-S50 support?
It supports Types K, J, T, E, R, S, B, and N thermocouples. -
Can the module handle both current and voltage signals simultaneously?
Yes, it supports input / either current or voltage signals but each channel is configured for one type at a time. -
What is the typical response time for an analog input signal conversion?
The response time is approximately 100 milliseconds. -
How does the module ensure signal integrity in electrically noisy environments?
Through galvanic isolation between input channels and to earth, it effectively minimizes noise and interference. -
What is the power requirement for the AAV141-S50 module?
It requires a 24 V DC power supply typically provided by the host control system rack. -
Is it possible to hot-swap this module during system operation?
No, the module must be replaced only when the system is in a safe, powered-down state to prevent data loss. -
What is the input accuracy / the module?
