Rtu Layout - Kingfisher PLUS+ Installation Manual

1. RTU Layout

The exact layout should be defined in layout and wiring drawings supplied with the RTU. If these have
not been supplied, then the RTU layouts shown below can be used as a guide.
Every RTU has a backplane (eg BA-4, BA-6), a power supply (eg PSU-3 or PS-11) and a processor
module (eg PC-1 or CP-11). The two common types of RTUs are shown below.
BA-4
PSU-3
PC-1
MAINS
POWER
An RTU can have additional communications ports (MC-11) and a wide variety of input/output
modules (eg. IO-4, AI-1, DI-5). Some of these are shown below.
BA-4
PSU-3
PC-1 MC11 IO-4
MAINS
POWER
If a communications module is used, standard practice is to install it to the right of the processor. IO
modules are usually installed in alphabetical order from left to right. Eg an AI-1 module would be
located to the left of a DI-5 module. The modules can be installed in any order if so desired (except a
PC-1 must be installed in the leftmost slot of a BA-4 backplane since it has two sockets).
