Description

BL591 Universal Isolated Signal Conditioners | Input up to ±1000 V | Passive current output | Isolation up to 500 V

Designed to measure currents and voltages with up to 500 V

  • Calibrated range selection
  • 10 selectable input ranges and unipolar as well as bipolar output signals
  • Universal power supply for 24 V DC supply or 100 … 230 V AC mains supply
  • Only 17.5 mm wide modular housing with comprehensive functionality
  • Passive output for direct connection to a supplying PLC
  • Monitor output for non-disruptive measurement of the output current by connecting a multimeter or permanently connecting an isolated display unit
  • Galvanic 3-port isolation for undistorted transmission of the measuring signals or damages
  • Highest reliability
  • Optimum price/perfomance ratio
  • 3 year warranty

The Transducer BL591 is designed to measure currents and voltages in applications with up to 500 V. Short circuit recognition, monitoring and control of motors, recognition of DC-link voltage or battery current/voltage are some use case examples. The input is galvanically isolated from output and auxiliary power. The housing can be quickly snapped on a DIN-Rail. The product comes with 10 selectable input ranges and unipolar as well as bipolar output signals. The device automatically calibrates itself after switching input or output ranges.
