I/O Systems - S700 I/OTU 709F

The TU 709F/710F terminal block serves as a base for the PROFIBUS communication interface CI 741F. The terminal block is rated for 24 V I/O signals. The following terminals are connected with each other inside the terminal block:
  • Terminals 2.8 and 3.8: supply voltage UP = +24 V DC
  • Terminals 2.9 to 4.9: reference potential ZP = 0 V for UP and UP3
