RO8S Relay Output Board
(with override switches)
Each RO8S connected to an AKC 55 must have a
unique address starting with 01. Each address switch has
an arrow pointer which is also a screwdriver slot for setting
the address.
The RO8S board is designed for 3” snap track mounting. It
can be mounted (1) inside of a Danfoss I/O enclosure, or
(2) in control panels where codes and good electrical
practice permit.
Up to 95 I/O nodes (OI8, RO8, SI8, AKC 16x Smart Case
Controllers, etc) can be connected to one AKC 55.
A maximum of 5 cable runs (1 shown) can be used to connect
any combination of nodes to the AKC 55.
The total length of all I/O cable runs (including stubs) is limited
to 5000 feet. Use point-to-point (“daisy-chain” connections
between boards.
The last I/O board on each cable run must be terminated.
Terminations are supplied with the AKC 55 controller as shown.
When necessary, individual I/O boards can be placed on
individual stubs up to a maximum of 25 feet long off a main
cable run.
