Features Applications Model
  • Installation on the S7-1500 mounting rail using one single screw
  • Uniform 40-pole front connector with push-in terminals
  • Connectable core cross-sections: 0.25 mm2 to 1.5 mm2 (AWG24 to 16)
  • Prewiring position of the front connector
  • Front flap with expandable cable compartment, even if fully wired
  • Unambiguous labeling on front of module:
  • Module type
  • Article No.
  • Hardware and firmware version
  • Channel numbers labeling
  • Cabling diagram
  • Included in the product package: One labeling strip for manual labeling
  • One U connector
  • Printed front door
  • Front connectors
  • Digital inputs record 24 V DC signals in the plant and forward them to the controller. Switches and 2, 3 or 4-wire proximity switches can be connected.
  • Digital outputs switch 24 V DC voltages in the plant and thus transfer internal signals from the controller to the plant. Solenoid valves, DC contactors, and indicator lights can be connected.
  • The low-cost 25 mm wide input/output module does not have settable parameters or diagnostic functions and can therefore be integrated very easily into the engineering. It is recommended for use in locations where only very few input/output channels are necessary or under conditions of use in which a high number of channels must be implemented in a very limited space.
