RO8 Relay Output Board

Each RO8 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 RO8 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.
