Analog amplifier MAC

As a compact cost effective unit, the MAC is designed to provide a closed loop control function for strain gauge transducers (e. g. web tension measurement). The MAC is optimized for use in electrical cabinets. There it can be DIN rail mounted or directly on a mounting plate. The enclosure of the MAC contains an amplifier and controller. The amplifier supplies the auxiliary power to the strain gauge transducers and conditions the output signals. Two voltage outputs with different filters are available. The independend function of the current output (option C and N) can be connected either to the high or low dampened voltage output. The external use of as 10 Volts / 20 mA signal converter is also possible. The PID components of the controller can be individually adjusted and also partially switched off. Additional adder and multiplier circuits enable the processing of other signals, e. g. diameter signal. 24 volts control signals can shut off the controller portion or gradually activate or deactivate the output signal.
