Product description
The main functions of 07AC91 module:
Analog input: Converts the external analog signal (such as the voltage signal out
put by the temperature and pressure sensor) into a digital signal for the control system to process.
Analog output: converts digital signals into analog signals to control actuators (such as valves, motors).
Isolation function: Good isolation performance to prevent interference signals from entering the control system.
