Description
Short description:WAGO’s signal conditioner converts, amplifies, filters, and electrically isolates analog signals.Features:Analog unipolar/bipolar signals at both input and outputDigital 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 valuesAdjustable software/hardware filterSafe 3-way isolation with 4 kV test voltage per EN 61140
Specification
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 |
