857-409

The 857-409 is a 3-way Bipolar Isolation Amplifier converts unipolar and bipolar standard signals and amplifies filters and electrically isolates analog standard signals. Clipping capability allows analog standard signal limitation to upper range values. The bipolar isolation amplifier records bipolar analog signals and converts them into bipolar, analog standard signals. After conversion, the isolated signals are transmitted with high accuracy to the output where they are available in an amplified form. In addition, unipolar signals and live zero signals can be adjusted independently of one another at both input and output via DIP switches. Adjusting the limiting frequency is also performed via DIP switches. Measured distance adjustment is carried out via zero/span potentiometers on the front of the device, while signal switching is performed in a calibrated way, which requires no adjustment when switching to another range.

• 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 maximum operating frequency
• Safe 3-way isolation with 2.5kV test voltage to EN 61140
