Product Details

SIMATIC S7-400, analog input SM 431, isolated 16 AI; resolution 16 bit, U/I/Resistor/Thermocouple/Pt100 , alarm, diagnostics

Q: Can I mix different sensor types on the same module?A: Yes, you can configure different groups of channels for different signal types (e.g., 8 channels for 4-20mA and 8 channels for Thermocouples) using the hardware configuration in Step 7 or TIA Portal.

Q: Is this module hot-swappable?A: When used with an active backplane bus in an S7-400 rack, it supports hot-swapping (insert/remove under power), provided your rack configuration allows it.

Q: What is the main difference between this and the 1KF20 model?A: The 7QH00 has 16 channels (vs 8), higher 16-bit resolution (vs 14), and direct support for Thermocouples and RTDs, which the 1KF20 lacks.
