Expert FAQs
- Q: Can I power multiple RTDs with one MTL4760ac?
A: No – each 4-wire RTD requires its own barrier module - Q: What happens if I exceed 95Ω resistance?
A: Signal accuracy degrades and safety certification becomes invalid - Q: Is this compatible with 3-wire RTDs?
A: No – designed specifically for 4-wire RTD configurations - Q: Can I use DC sensors with this barrier?
A: No – optimized for AC signals only - Q: What replacement fuse should I use?
A: Only 50mA rated fuses to maintain safety certification
