The Task Guaranteeing reliable and safe system operation requires galvanic isolation between the sensor and the control (e. g. DCS, PLC etc.). The Problems In particular with large-scale systems, the difficulties often lie in the financial pressure in addition to the lack of space for mounting the isolators. Up to now, low-cost single-range isolators have, however, caused relatively high purchase, logistics and storage costs, for example, also for stocking of spare parts. The Solution The calibrated switching of the input and output ranges allows the VariTrans® B 13000 basic low-cost standard signal isolators to be used universally without complicated recalibration. The settings are made simply using DIP switches. The Housing The modular housing, just 12.5 mm in width, can also withstand high mechanical loads. The housing is easy to open providing access to the adjusting elements. The Advantages The analog transmission of the measuring signal with transformer isolation and the new digitally controlled range selection guarantee troublefree use in all standard industrial applications. The Technology A microcontroller monitors the control element settings and controls the calibrated range selection. Interference to the signal transmission – for example, due to contact resistances in the range switches – are thus ruled out. The integrated power supply is configured for 230 V AC or 24 V AC/DC. The extremely low power consumption and the related minimal self-heating significantly increase the reliability. That’s why we give a 5-year warranty.
