Short description:
The 857-450 Loop-Powered Isolation Amplifier converts analog, unipolar and bipolar,
standard signals. It is also designed to amplify, filter and electrically isolate standard
analog signals.
Characteristics:
• No additional supply voltage required
• Zero/span adjustment
• Analog, unipolar and bipolar, standard signals at input
• Calibrated scale switching
• Switchable max. operating frequency
• Safe 2-way isolation with 2.5 kV test voltage to EN 61140
