PHM-7504 Four-channel analog output module
Product overview
The full isolation design between power supply, communication and input ensures the reliability of the product, the stability of signal acquisition, and anti-interference performance. The optimal isolation design concept is very suitable for the complex industrial working conditions and has good stability.
Compared with the traditional PLC+signal isolator mode, it has reduced the errors because of the two conversions.
