Analog Output Module (K-AO01)

8-channel analog output module, linearly controlling proportional valves and VFDs with precise 4-20mA currents.

K-AO01 converts CPU commands into physical signals to control continuous actuators. Utilizing high-quality DAC chips, it outputs extremely stable 4-20mA currents, enabling control valves to open to exact stroke percentages, optimizing the most demanding PID loops in chemical and power plants.
