IsoPAQ-641

High-performance isolation transmitter for mA/V Signals with calibrated range selection

The Isolation Amplifier IsoPAQ-641 is used for isolation and conversion of 0/4 … 20 mA and 0/2 … 10 V standard signals.

The input and output range of IsoPAQ-641 can be easily set by using DIP switch. Due to the calibrated range selection no further adjustment is necessary. Also the cut-off frequency can be adapted to the measurement task by using the DIP Switch.

The auxiliary power can be supplied via the connection terminals or via the optional In-Rail-Bus connector. A green LED on the front of the unit has been provided to monitor the power supply.

  • Calibrated signal setting via DIP switch
    Input and output range can be set by using DIP switch – high
    precision without any further adjustment
  • 3-Port Isolation
    Protection against erroneous measurements due to parasitic
    voltages or ground loops
  • Extremely slim design
    6.2 mm slim housing for a simple and space saving
    DIN rail mounting
  • Optional In-Rail-Bus mounting rail connector
    Allows for fast and economical installation
  • Protective Separation acc. to EN 61140
    Konstruktionen och den höga isolationsnivån skyddar servicepersonal och enheter nedströms mot otillåten hög spänning
  • Maximum reliability
    No maintenance costs
