Short description:
The 857-409 Bipolar Isolation Amplifier converts unipolar and bipolar standard signals
and amplifies, filters and electrically isolates analog standard signals.
Characteristics:
• Overload protection of current input using reversible fuse
• Zero/span adjustment across the entire measuring range
• Calibrated scale switching
• Standard analog unipolar and bipolar signals, input/output
• Switchable max. operating frequency
• Clipping capability allows analog standard signal limitation to upper range values.
• Safe 3-way isolation with 2.5kV test voltage to EN 61140
