Fig. 16 Universal IO Wiring Examples
NOTE:
• UL Standards recommend all wiring connections for the IO, SSR, 24 VAC / VDC circuits are restricted to the
same room.
• Use a protective diode for any circuit that allows the current to flow forward because the current will not flow
in the reverse direction. The diode protects the components responsive to the current flow through them in the
wrong direction.
