Chapt.3 Precautions for I/O Modules
DC Output module
External equipment
T
P1
A power supply should be basically used for P1 and P2.
In the above case, insert a diode for preventing a back current in the
position A so that a back current is prevented from flowing into P2.
<Case 2>
When the power cable connected to the P24 terminal is cut off,
external load may be driven because the load current of OFF output
circuit(OUTO) flows through the diode and the transistor of ON output
circuit(OUTI) as shown below.
