Scope of Supply Amplifier in field enclosure Standard (option U): 2 voltage outputs (direct / filtered) Variants C: 1 current output 4...20 mA, (direct / filtered), N: 1 current output 0.20 mA, (direct / filtered) Additional Options E: Enlarged excitation supply 160 mA Special Features • Amplifier with integrated excitation supply, 2 voltage outputs • 2 independent limit switches with adjustable hysteresis • Precision adder with weighted inputs to calculate • Adjustable filter • Signals and power supply galvanically isolated The amplifier MV127 with additional functions is offered in a field enclosure. This makes it possible to amplify and analyze sensor signals in rough environments close to machines and equipment. The amplifier has two potentiometers to compensate pre-coads e.g. the roll weight. The desired gain is adjusted with two additional potentiometers - coarse and fine. All additional functions including the limit switches work with standardized voltage signals in the range of -10 V .+10 V. The ON and OFF switching points of the limit switches can be independently adjusted over the total voltage range. This enables the flexible use as two point controller. The inputs and outputs of the adder and both wide range limit switches are placed separately on terminals and can be used for internal or external signals.
