Description
Short description:WAGO’s current signal conditioner measures AC/DC currents up to 100 A, while converting the measured current into an analog standard signal at the output.Features:Both digital signal output and relay with changeover contact react to configured measurement range limits (on/off switching delay and threshold value switch function can be configured with up to two threshold values).Clipping capability for analog signal limitation to output end valuesAdjustable software filterSafe 3-way isolation with 3 kV test voltage per EN 61010-1
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 |
