ABB PP846A is a power module that typically consists of an input conversion section, an amplifier, and a feedback section. The input conversion section includes sensitive components, which sense the measured parameters and convert them into an intermediate analog quantity. The intermediate quantity can be physical quantities such as voltage, current, displacement, and force. The feedback section converts the output signal of the transmitter into a feedback signal. The amplifier amplifies the difference between the intermediate analog quantity and the feedback quantity and converts it into a standard output signal.
