Delay time is the time from the receipt of an output on or off command to the output actually turning on or off.
(2)
If using 0.5 A outputs, alternate wiring so that no two 0.5 A outputs are next to each other.
ATTENTION
1794-OM16 module outputs are not fused. Fused outputs are recommended.
If not using a 1794-TBNF terminal base and fusing is required, external
fusing must be provided.
