Measurement Amplifier MV127

Product catalog summary

Overview: The MV127 is a measuring amplifier designed for use in harsh environments near machinery. It amplifies and analyzes sensor signals and includes additional functions such as limit switches and a precision adder.

Specifications:

Amplifier Features: Integrated excitation supply, two voltage outputs, and galvanically isolated signals and power supply.
Limit Switches: Two independent switches with adjustable hysteresis, operating within a voltage range of -10 V to +10 V.
Precision Adder: Weighted inputs for calculation, with input voltage range of -10 V to +10 V.
Filter: Adjustable low pass filter with a signal raising delay of 0.13 to 4.8 seconds.

Technical Data:

Strain Gauge Excitation Supply: 10 V, max 60 mA, with an option for 160 mA.
Amplification: Adjustable range from 400 to 3200 V/V, factory set at 667 V/V.
Signal Outputs: Voltage outputs range from -10 V to +10 V, with a minimum load resistance of 5 kΩ.
Current Outputs: Options for 4-20 mA or 0-20 mA, with a max load resistance of 600 Ω.
Limit Switches: Input resistance of 47 kΩ, with a switching response time of 10 ms.
Supply Voltage: 24 VDC, ±10%, with a current consumption of approximately 250 mA.
Temperature Range: 0 to 60°C.
Enclosure Protection: IP 65, with dimensions of 140 x 140 x 91 mm.

Variants and Options:

Standard Option (U): Two voltage outputs (direct/filtered).
Variant C: One current output (4-20 mA) and two voltage outputs.
Variant N: One current output (0-20 mA) and two voltage outputs.
Additional Option E: Enlarged excitation supply of 160 mA.

Special Features: The amplifier includes an integrated excitation supply, two independent limit switches, a precision adder, and adjustable filters, all designed to work with standardized voltage signals.

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.
