MP-V-9A has nine I/O points and the controller is equipped with four pluggable terminal blocks.
Recommended screw tightening torque: 0.56 Nm (5 lbf.in)
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
