Application-Specific FAQ
Q: Can the BMXART0814 read both RTD and thermocouple sensors simultaneously?
A: Yes. Each of the 8 channels is independently configurable in software; you can mix RTD and TC sensor types on the same module.
Q: Is cold-junction compensation (CJC) built in for thermocouple measurements?
A: Yes. The module includes an internal CJC sensor, eliminating the need for external compensation hardware.
Q: Which version of EcoStruxure Control Expert is required?
A: Unity Pro v6.0 or later (EcoStruxure Control Expert v13.0+) is recommended for full diagnostic function block support.
Q: Can this module be used in a remote I/O drop (Ethernet or CANopen)?
A: The BMXART0814 is a local backplane module. For remote temperature acquisition, consider the STBAHI8321 (Advantys STB) or BMXNOE0100 with distributed I/O architecture.
Q: What is the maximum cable length for RTD sensors?
A: Schneider Electric recommends a maximum of 300 m for 3-wire Pt100 connections to maintain accuracy within specification.
Q: Is the BMXART0814 still in production?
A: This module is in the mature/maintained phase. Konmask.com maintains stock for MRO and system expansion needs. Contact us for long-term availability planning.
