5.2 Installation
The following RBCs can be installed in a Series 505 base.
• PPX:505–6870, communicates over PROFIBUS-DP I/O channel using
12 Mbaud RS-485 cable. (Note: Series 505 Special Function modules
cannot be used in a DP base.)
• PPX:505–6851–A/B, communicates over Series 505 remote I/O channel
using 1 Mbaud RS-485 cable. This RBC can be used in a redundant
configuration (i.e., you can use two RBCs, and/or two power supplies) in
the PPX:505–6511 base. The RBC does not support dual media
(cabling).
• 505–6850–A/B, communicates over Series 505 remote I/O channel
using a PPX:505–6860 adapter to connect between coaxial cable and
1 Mbaud RS-485 cable. This RBC can be used in a redundant
configuration (i.e., you can use two RBCs, and/or two power supplies) in
the PPX:505–6511 base. The RBC also supports dual media (cabling).
RBCs used in a Series 505 base must always be installed in the second slot
from the left, adjacent to the power supply module. See Figure 5-2.
