Multi Channel Measuring Amplifier

Technical Description

This measuring amplifier is used to provide power to multi-channel measuring amplifiers in half- or full-bridge circuit and process the measuring signals. It is equipped with a serial interface in order to process the values on a PC. The basic unit has 16 measuring channels. The maximum extension, with three auxiliary modules, results in 64 channels. The amplifier is operated simply with four keys located on the front panel. Channel numbers and measured values with units are shown on the two-line LCD. The measurement encoder is connected to the associated balance potentiometers with either a 68-pin multiple input port or 16 single ports (6-pin).
