FX2NC Series Programmable Controllers Outputs 6.

6.3.3 Triac output example
6.4 Applying safe loads
Ensure all loads are applied to the same side of each PC output, see previous figures.
Loads which should NEVER simultaneously operate (e.g. direction control of a motor),
because of a safety critical situation, should not rely on the PC's sequencing alone.
Mechanical interlocks MUST be fitted to all safety critical circuits. (See preceding figure.)
