Wiring Dynamic Outputs (3G2A5-OD211)
By using the OD211 DC Output Unit, a large number of outputs can be controlled through only 16 bits. Just like the
ID211 DC Input Unit, different combinations of bits can control different outputs. Using this type of Unit can simplify
wiring when many outputs must be controlled. Up to 64 outputs can be accessed.
Because the output data is positive logic, a terminal output goes high when the output bit is ON (1). A strobe output
is negative logic, so when the output bit is ON (1), the corresponding terminal goes low. Use positive logic output
devices for the load of this Unit. The strobe output is cyclic and automatically output.

Note Because the DC Input Unit is operated on an extremely small current, make sure there is adequate distance
between the DC Input Unit wires and high-tension equipment or power lines. If this cannot be avoided, use
shielded cables when wiring the DC Input Unit. Be sure to keep the total length of the wires less than 10 m.
