IsoPAQ-661
Isolation transmitter for Bipolar and Unipolar mA/V signals with calibrated range selection
The Bipolar Isolation Amplifier IisPAQ-661 is used for isolation and conversion of bipolar and unipolar industrial standard signals.
The input and output range of IsoPAQ-661 can be easily set by using DIP switch. Due to the calibrated range selection no further adjustment is necessary.
A switchable compensation of the measuring range can be performed at the Zero/Span potentiometers on the front panel. 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.
