Also, do you need a special cable to drive two monitors?

You may also want to consider other specialists – a translator for instance.

It is easy to mix cables, because the connectors are the same.

Use a remote switch (teleruptor) with auxiliary contact.

When someone uses a lighting contactor in a motor application, that's a misapplication.

In most cases, the contactor does not simply wear out from normal use.

A contactor really has only two basic parts: the contacts and the coil.

The remote switch sends an electrical pulse to the motor each time one of the push buttons is pressed.

The same is true when someone uses a "normal operation" motor contactor for motor jogging duty.

In addition, the m84 has 8 inputs for manually switching the relays (similar to the 7244 universal relay).

This happens because of a default function of the actuator that makes it works as a step relay.

Since a contactor should last for years, don't automatically replace one that fails with an identical unit.

Finally, in the last case, a roller shutter must be connected to two or more control points; this requires the use of a remote switch, a key box and push buttons.
