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 three relay outputs
One 2-position fixed terminal block for the high power relay output
One 6-position plus one 2-position pluggable terminal blocks for the five universal inputs/outputs of type Ub
