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
