BỘ KHUẾCH ĐẠI TÍN HIỆU  VARITRANS P 29000

The Task

When it comes to taking measurements on power electronics, unipolar or bipolar voltage signals ranging from 20 mV to 1000 V must be galvanically isolated and converted to standard ±20 mA, ±10 V, or 4 … 20 mA output signals.

The Problems

 Room in the enclosure is limited and expensive. Therefore great value is placed on the miniaturization of automation components. And high safety requirements with regard to the protection of persons and systems must also be met.

The Advantages

 The measuring ranges of the VariTrans P 29000 are adjusted via DIP switches on the front side of the modular housing. The switch coding is printed on the housing. Calibrated switching is controlled by a microcontroller. This makes for very easy configuration requiring neither calibrators nor other measuring equipment. The user can select from up to 192 switchable calibrated ranges. In addition to the active current or voltage output, a passive current output allows for connection to active PLC inputs. LEDs indicate proper functioning or possible fault conditions, such as exceeding of the allowable load voltage at the output. The simple implementation of special measuring ranges supports solutions tailored to your application. An optional RangeLimit function lets you set lower and upper output limits on the transducers. The output can be inverted by the user. A connectable potentiometer enables zero point adjustment of up to 5 % on the measuring section to compensate for sensor drift, for example. The VariTrans P 29000 itself requires no manual zero point adjustment.
