Condition:New
Type:Logic ICs
Model Number:8 K -type
Model:PD3060-K
Renovation and construction content:Hydropower Engineering
Compatibility :
PD3060-K type thermocouple temperature acquisition module , and PD3060-PT100 temperature acquisition module , just different sensors connected
Communication parameters are identical.
VersusPD3015Series of temperature and humidity acquisition module communication protocolExactly the same format , test software are identical, but
Humidity register moot.
