Measuring amplifier/signal conditioner in 5B format.

The MA series measuring amplifiers adjust signals of different type and size to the 5 V input of a PC data acquisition system. With 10 kHz or 50 kHz bandwidth, it is ideal for dynamic signals. The pin assignment of the modules corresponds to the 5B module standard of Analog Devices and Burr Brown. An additional 0EX pin has been introduced for sensors requiring unipolar supply to be suitable for connection.
The model MA-UNI is the all-rounder in signal conditioning optimizing performance and accuracy of your measuring system. You want to measure voltage, current, resistance or temperature (RTD)? Feasible, of course, with the MA-UNI: All common sensors as well as LVDTs (carrier frequency) and measuring bridges (strain gage) can directly be connected. Numerous measuring ranges are provided for optimum signal conditioning.

  • 5B technology. Industrial standard.
  • Depending on model: 10 kHz or 50 kHz bandwidth.
  • Galvanic isolation.
  • Input signals depending on model voltage, current, resistance, PT100, measuring bridges (strain gauge), LVDT (carrier frequency).
  • 3 switchable filter cut-off frequencies.
  • Adjustable with potentiometers.
  • Supply power +5 VDC.
