What is the Wago 2857-401?
Short description:
WAGO's 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
Safe 3-way isolation with 4 kV test voltage per EN 61140

Notes
| Note | This product is powered by 24 VDC, which can be bridged 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 maximum permissible total current of 6 A is not exceeded., Additional setting options via the WAGO Interface Configuration Software |
