The UR1 rack (like this one) is a single-tier rack for straightforward, single-row module configurations. The UR2 rack is a two-tier, segmented rack that allows for more complex, high-density setups and can be split into two electrically isolated segments. Question? Can I use S7-300 modules in this S7-400 rack? No, S7-400 racks are exclusively designed for S7-400 series modules. The form factor, backplane bus connector, and communication protocol are different from the S7-300 series, making them incompatible. Question? Is a separate power supply required for this rack? Yes, the 6ES7400-1TA01-0AAO is a passive rack. A dedicated S7-400 power supply (PS) module must be installed in the dedicated power supply slot(s) to power the backplane bus and the connected modules. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
