MP-C-18A Screw Terminals

MP-C-18A has 18 I/O points and the controller is equipped with seven pluggable terminal blocks and one fixed terminal block.

Danger Danger

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Disconnect the power supply and other high voltage equipment before wiring.

Failure to follow these instructions will result in death or serious injury.

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

  • Two 3-position pluggable terminal blocks for the four triac outputs

  • One 6-position pluggable terminal block for the three relay outputs

  • One 2-position fixed terminal block for the high power relay output

  • Two 6-position plus one 3-position pluggable terminal blocks for the 10 universal inputs/outputs of type Ub
