The terminal blocks are used as follows:

  • One 2-position pluggable terminal block for the power input

  • One 6-position pluggable terminal block for the four universal inputs

  • One 4-position pluggable terminal block for the three digital (triac) outputs

  • One 5-position pluggable terminal block for the two analog (voltage or current) outputs
