The terminal blocks are used as follows:

  • One 3-position pluggable terminal block for the power input

  • One 6-position pluggable terminal block for the four universal inputs/outputs of type Uc

  • One 8-position pluggable terminal block for the four relay outputs

  • Four 6-position pluggable terminal blocks for the 16 universal inputs/outputs of type Ub
