Item no. 2857-401

Isolation amplifier; Bipolar current and voltage input signal; Bipolar current and voltage output signal; Digital output; Supply voltage: 24 VDC; 12.5 mm module width

Stock item
Short description:

This signal conditioner converts, amplifies, filters, and electrically isolates analog signals.

Features:

  • Analog unipolar/bipolar signals at both input and output
  • Digital signal output reacts to configured measurement range limits (configurable on/off switching delay and threshold value switch function with up to two threshold values).
  • Digital HOLD input freezes the output signal.
  • Clipping capability for analog signal limitation to output end values
  • Adjustable software/hardware filter
  • Input/output response simulation via configuration display
  • Safe 3-way isolation with 4 kV test voltage per EN 61140

Note:
  • The device is supplied with 24 VDC, which can be commoned using lateral push-in type jumper bars: (6.1) US+ (BR) and (6.2) GND 2 (BR). With this variant, it is necessary to ensure that the max. permissible total current of 1 A is not exceeded.
  • Additional setting options via WAGO Interface Configuration Software or WAGO Configuration App
