IsoAmp® 3000/4000 The DC isolation amplifiers of the IsoAmp ® 3000/4000 series transmit and convert impressed 0(4) ... 20 mA or 0 ... 10 V standard signals according to our German patent DBP 34 12 843 with a high level of accuracy. They provide Safe Isolation and high insulation from input to output to power supply.
The control range extends into the negative values and allows strict linear transmission in the zero range. Compared with conventional unipolar amplifiers, this has a great advantage: The often asymptotic setting of the zero point, for example, when calibrating with a sensor, is ruled out.
The transmission error is unusually low. The reason for this is mainly a negative feedback circuit that is incorporated in the electrical isolation. It has no sensing resistor with 1:1 transmission and just one sensing resistor for current/voltage conversion. Differentiated signal return allows the circuit to remain stable even with strong complex loads.
The components required in conventional concepts for matching amplifiers and resistor networks are omitted. The reliability is accordingly high.
The computer-aided production control and final inspection ensure high and constant quality. The full encapsulation guarantees maximum safety and reliability even in extreme conditions.
