Miniature amplifiers for voltage and current Perfectly conditioned. Voltage and current signals can optimally be ad- justed to the input of a PC data acquisition system with the miniature measuring amplifier MAL-UI. It features a 5V sensor supply for connected sen- Minimum size. Great performance. Small price. The miniature format of the MAL-UI is ideal to realize measurement applications even if the in- stallation is in problematic locations. Despite the small size, the measuring amplifier features great functionality. All this at a reasonable price. figured for the MAL-UI via solder bridges. A ±5V signal proportional to the input signal is pro- In addition to signal conditioning of voltages, the MAL-UI can be used for current measurement in the ±2OmA range. Changing the operating mode is done via soldering bridges on the bottom side The MAL series provides a great variety of measuring amplifiers, measuring converters, or filter modules. They can be used in any combina- tion allowing for the solution of the most individ- With the backplanes of the BP series varying in size and design, signal connection is easy. The modules just have to be plugged on the relevant sensor supply signal conditioning differential amplifier Functional diagram bavarian measurement company munich

The measuring amplifier is plugged onto a 24-pin socket. If the marking of the socket is on the left, pin 1 is bottom left. ! Check for correct poling. Change modules only at no load! 2 Pin assignment The pin assignment of the MAL-UI is illustrated in the figure above and in the following table. Pin sensor supply +5V HI signal input LO signal input sensor supply 0V power supply ground - supply -7.5V..-15V amplifier output ±5V supply +7.5V..+15V 3 Jumper configuration The MAL-UI can process both voltage (measuring range ±10V, ±5V ±1V) and current (measuring range ±20mA) signals. Switching to another...

The module output is proportional to the input voltage in all operating modes and ranges. Apply cable shield at one end only. If earthing is required, connect the screen only at one end, otherwise there is a risk of hum DC voltages within the allowed input range are provided at the output as a ±5V signal to be connected to a PC data acquisition system. Connect LO and OEX for unipolar measurement. For current measurement with MAL-UI, a 50Q shunt is activated (PL5 closed). The measurement is done in the ±1V measuring range. Do not connect any power sources as otherwise the shunt might be 5 Other...
