BL590 Universal Isolated Signal Conditioners | Input up to ±1000 mV | Passive current output | Isolation up to 500 V
Product number:
BL590
Description
BL590 Universal Isolated Signal Conditioners | Input up to ±1000 mV | 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 BL590 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.
We look forward to hearing from you!
