MP-C-24A Screw Terminals

MP-C-24A has 24 I/O points and the controller is equipped with seven pluggable terminal blocks.

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

  • One 6-position pluggable terminal block for the four universal inputs/outputs of type Uc

  • One 8-position pluggable terminal block for the four relay outputs

  • Four 6-position pluggable terminal blocks for the 16 universal inputs/outputs of type Ub
