Delivery release for SIMATIC IOT2000 Input Sink / Source Module

  • Entry
  • Associated product(s)
With its ten digital inputs, the SIMATIC IOT2000 Input Sink / Source Module allows for the direct connection of non-time-critical sensor data to the SIMATIC IOT2000.

Due to the isolated design of the inputs, the input wiring can be either in Sink or Source.
The module can individually read in each channel as Sink / Source (respectively source or sink input) without additional configuration.

Product description

Major highlights:

  • High industrial functionality
  • ARDUINO shield with 10x DI Sink / Source
  • Operation of Sink / Source integrated in hardware (no software switchover necessary)
    • Can be selected individually for each channel
  • Fast assembly, as the suitable cover and fastening material are included in delivery
  • Industrial design
  • Use of the industry-standard voltage ranges (e.g. 24 V with digital in)
  • Tested environmental conditions, such as IOT2040 (e.g. for 0 .. 50° C)
  • Approvals such as IOT2040 (CE UL)
  • Developed and tested for 24/7 operation
  • Highest degree of variability for creating applications
  • Addressing the module via GPIOs allows the arbitrary selection of the programming language and development environment, e.g. Node-RED
