FAQ
-
What is the maximum input voltage that MU-PAIL02 can tolerate without damage?
The input channels can typically withstand ±30 VDC transient overloads, but continuous operation should remain within ±25 mV. -
Is the module capable / detecting open circuit conditions on all channels?
Yes, each channel has built-in diagnostics for open circuit detection. -
How is signal isolation achieved on this module?
The module /fers galvanic isolation between each channel and the backplane, as well as between channels. -
Can this module accept thermocouple signals directly?
Yes, it is designed to interface directly with thermocouples without requiring external signal conditioning. -
Does the MU-PAIL02 perform linearization for thermocouples?
No, linearization is handled at the control processor level, not within the module itself. -
What is the noise rejection capability / the MU-PAIL02?
The module employs digital filtering with excellent common-mode rejection (>100 dB typical). -
Can it be used in a redundant configuration?
Yes, when used with redundant I/O backplanes and system configuration, it supports fault-tolerant deployment. -
What is the input impedance / each channel?
Greater than 10 MΩ, ensuring minimal loading on connected sensors. -
Is calibration required for each channel?
Factory calibrated; field recalibration is generally not required unless performance deviation is observed. -
What is the maximum cable length supported for sensor connections?
Cable lengths depend on signal type and shielding, but typically up to 100 meters with shielded twisted pair is supported for low-noise operation.
