Abstract
A signal converter which receives signals from a plurality of sensor terminal ends to detect physical quantities in a plant and conducts a necessary correction for the signals to send the signals to a host computer or which transmits signals from the host computer to operation terminal ends in the plant includes a sensor terminal end amplifier including a processing unit for receiving a signal from a sensor terminal end and conducting a predetermined amplifying operation for the signal and a storage unit in which information items related to the sensor terminal and the processing unit are stored, an operation terminal end amplifier including a converting unit for converting signals into predetermined control signals which can be received by the operation terminal end and a storage unit in which information items related to the operation terminal end and the converting unit are stored, and a signal converting section including a connecting unit for connecting the sensor terminal amplifier section to the operation terminal amplifier section and a signal processing unit for conducting signal processing to communicate with the host computer.
