(including the other analog expansion boards, analog special adapters)
2) Thermometer types Pt1000 and Ni1000 can be connected. (However, it's impossible to use both types
Pt1000 and Ni1000 with 1 adapter.)
3) The temperature data will be automatically written to the special data register of the FX
3S/FX3G/FX3GC/
FX
3U/FX3UC Series PLC.
Refer to the system configuration shown in the User's Manual - Hardware Edition to check the number of
