❓ FAQ – Selection & Application Guide
- Q: Can AI950B connect to sensors in Zone 0?A: Yes, the module is for Zone 2 but connects to intrinsically safe sensors located in Zone 0, 1, or 2.
- Q: What is the advantage of channel-to-channel isolation?A: It prevents ground loops and interference between channels. Ideal for precise temperature measurements.
- Q: Does it support 4-wire RTD connections?A: Yes, AI950B supports 2, 3, and 4-wire RTD for Pt100, Pt1000, and Ni100 sensors.
- Q: How do I choose internal vs external cold junction?A: Use internal for terminal temperature, external for remote reference. Configure via FDT/DTM.
- Q: Can I replace this module without removing power?A: Yes, hot swap is fully supported. No need to power down the backplane.
