•
The input and output circuits of this product are compatible with both NPN/PNP open collector
output. However, mixing NPN and PNP is not allowed.
•
If the open collector to be connected is NPN, use NPN to all the input and output circuits. If the
open collector to be connected is PNP, use PNP to all the input and output circuits. Refer to the
CHECK
connecting sample shown above for wiring.
•
Be sure to use the interlock function for this product for safety, and refer to the connecting
samples of both input common and output common for wiring.
