MAL-ISO Series
4Pages

Isolation Amplifiers Perfectly Conditioned. Isolated. Voltage (MAL-ISO50/10/5/1) and current signals (MAL-ISO20mA) can optimally be adjusted to the input of a data acquisition system with the differential amplifiers MAL-ISO. The isolation of the analog inputs guarantees reliable measurement results. Minimum Size. Great Performance. Small Price. The miniature format of the MAL-ISO is ideal to realize measurement applications even if the installation is in problematic locations. Despite the small size, the measuring amplifier features great functionality. All this at a reasonable price. Clearly Safe. The galvanic isolation provided by the isolation amplifiers guarantees interference-free operation and protects the DAQ system and the PC against high potentials. Voltage or Current. The amplifier types differ in their input voltage range of ±1V up to ±50V (MAL-ISO50/10/5/1) for voltage measurement and ±20mA (MAL-ISO20m) for current measurement. A ±5V signal proportional to the input signal is provided at the output. Compatibility. The MAL series provides a great variety of measuring amplifiers, measuring converters, or filter modules. They can be used in any combination allowing for the solution of the most individual measuring tasks. Get Connected. 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 slot of the backplane.

1 Available Versions Product 2 Installation 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! Ansicht von unten/ Bottom view 3 Pin Assignment The pin assignment of the modules is illustrated in the figure above and in the following table.

4 Interfacing Examples 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 pick-up. 4.1 Voltage Measurement DC (MAL-ISO50/10/5/1) DC voltages within the allowed input range are provided electrically isolated at the output as a ±5V signal to be connected to a PC data acquisition system. 4.2 Current Measurement (MAL-ISO20mA) For current measurement with MAL-ISO20mA a 50Q shunt is active. The measurement is done in the ±1V...
