PROFI-8255-G CR
PROFIBUS Remote I/O Unit with 2 I/O Slots
The PROFI-8155/8255 Remote I/O Unit is specially designed for the slave device of PROFIBUS DP protocol. It supports up to 1/2 slots for ICPDAS I-8k series, I-87k Low Profile series, and I-87k High Profiles series I/O modules. In addition, we also provide hot-swap function for I-87k High Profiles series I/O modules. To setup network, users can choose and configure I/O modules by using the GSD file without any other setting tools.
