Specifications

Notes

  • Note: This product 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 maximum permissible total current of 2 A is not exceeded.Additional setting options via WAGO Interface Configuration Software or WAGO Configuration Display
