C Bus Upgrades

WORKS: C Bus power supply and Relay upgrades

Client: Telstra - Global Operations Centre


Scope of Works

Being one of the first large scale C-Bus Projects installed many components are now nearing their used by date.

To maintain the operational integrity of the system it was requested that JNJ change over many of the original enclosed module power supplies and standalone relay units.

New Din rail C-Bus2 modules were supplied and installed by JNJ during a scheduled shut down period.


As there was no initial cabling standard for C-bus the system was wired using a different cabling method.

This wiring method was not compatible with the new C-Bus 2 modules which were connected with RJ45 plugs.

A methodical approach was required to ensure the new and old cabling systems were modified to be compatible with each other.
