IsoPAQ-661 isolation converter for bipolar and unipolar current and voltage signals INOR

Description

The IsoPAQ-661 isolation converter for bipolar and unipolar INOR current and voltage signals with calibrated range selection is used for isolation and conversion of bipolar and unipolar standard industrial signals.

The input and output range of the IsoPAQ-661 can be easily set using a DIP switch. No further adjustment is needed due to the calibrated range selection. Switchable compensation of the measuring range can be done with zero and span potentiometers on the front panel. The cutoff frequency can also be adjusted for the measurement task using a DIP switch.

The auxiliary power supply of the isolation converter can be supplied via terminal connectors or via the optional In-Rail-Bus connector. There is a green LED light on the front of the unit for power monitoring.

Main features of the IsoPAQ-661

• calibrated signal adjustment via DIP switch:
  input and output range can be adjusted via DIP switch – high accuracy without further adjustments
• high bandwidth; short response time:
  no distortion of the signal; no falsification of the measured signal
• switchable zero and span compensation:
  to adjust the sensor or field device
• 3-input isolation:
  protection against false measurements due to parasitic voltages or earth loops
• Extremely slim design:
  6.2 mm slim housing for easy and economical DIN-rail mounting
• optional In-Rail-Bus connector for attachment:
  enables fast and economical installation
• safe isolation according to EN 61140:
  protection for service personnel and downstream installations against unacceptable high voltage
