Applying safe loads
Ensure all loads are applied to the same side of each PLC 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 PLC's sequencing alone.
Mechanical interlocks MUST be fitted to all safety critical circuits. (See preceding figure.)
