The universal amplifier modules are low-cost and versatile modules in 5 B technology models University of MA and MA-U/I by BMC meßsysteme GmbH. You are in all 5B Backplanes can be used and can ideally be combined with systems MC-COMPACTand span >MV COMPACT. The universal amplifier model MA-UNI, can be used for potential-free measurement of voltage, current, resistance, PT-100 and DMS. A source for the sensor power supply or excitation and a carrier frequency make compatible generator for inductive sensor this module to virtually all common sensors. The model MA-U/I only has voltage and current measuring ranges, features for a more powerful sensor power supply ± 12 V ± 30 mA.
