The last row of table 4-4 (R53) explicitly allows 1 custom circuit to be controlled by each PCM channel.
Do keep a good eye on the per-channel and total current drawn by the PCM in any given state.
Another alternative is to use a
12V opto-isolated relay module. These can be controlled from DIO ports or relay ports, and are much smaller and less expensive than a spike for custom circuit loads of up to 10A.
