CERTUS CBT is an expansion module which allows the

connection of the CMM with other expansion unit modules

placed at great distances. Up to 50m per connection.

Maximum 6 connections/system.

Through the use of a shielded cable (compatible with RS485

standard) two CBT modules placed at the desired distance

can be linked together.

Each CBT2 has two independent connection channel; the

connection of two CBT2 can be performed by wiring a

channel of your choice.

CBT1 has only one channel and must be connected as the

first or last module.

The CERTUS system units are provided with terminal blocks for the electrical connections. Each unit can have 16 or 24

terminals. Each unit also has a rear panel plug-in connector (for communication with the master and with the other expansion

units). The C 2R and C 4R are connected via terminal blocks only.
