scheda tecnica:
This model is used for PLC user. The design of isolation between I-7520 and I-7520R/AR is different. If the user want to supply the power from PLC, he should use the I-7520R/AR. Otherwise the isolation will be broken. Please refer to the manual I-7000 bus converter for detail information.
