MP-C-15A Screw Terminals
MP-C-15A has 15 I/O points and the controller is equipped with six pluggable terminal blocks and one fixed terminal block.
Recommended screw tightening torque: 0.56 Nm (5 lbf.in)
The terminal blocks are used as follows:
One 3-position pluggable terminal block for the power input
Three 3-position pluggable terminal blocks for the six triac outputs
One 2-position fixed terminal block for the high power relay output
Two 6-position pluggable terminal blocks for the eight universal inputs/outputs of type Ub
