Signal Amplifier
A signal amplifier is required only in applications where the control signal to the proportional valve is a potentiometer, computer or programmable logic control (PLC) delivering a low level 4-20 mA or 0-10 VDC signal. In such applications the amplifier boosts the control signal to the necessary power requirements of the proportional valve coil.
