Advantys FTB splitter boxes are of the monobloc type.
Each splitter box comprises one part for connection of sensors and actuators by
means of M12 connectors, and one part for connection of splitter boxes on InterBus
fieldbus.
This splitter box enables inputs/outputs to be located remotely, as close as possible
to the equipment being controlled.
InterBus bus presentation
InterBus is a serial link type fieldbus for sensors and actuators which satisfies the
requirements of industrial environments.
Conforming to the standard specification, an InterBus can operate with up to 256
Slaves:
b 12.8 km (41,999 ft.) with copper conductors,
b beyond 80 km (262,500 ft.) using fiber optic cables.
The distance between 2 different components of the bus must not exceed 400 m
(1312 ft.) when using copper conductors.
The InterBus system is designed in the form of a loop and has the structure of a shift
register distributed on the bus. Each Slave, with its registers, constitutes a
component in this shift register loop.
The cyclic exchange of information between the Master and the Slaves is carried out
independently by the Master.
The physical link consists of 3 pairs of twisted wires with common shielding.
In addition to the main bus (long distance bus), a local bus can be set up.

24 V power supply also passes along the system cable (3 additional
wires, 0.75 mm 2 / #19 AWG) to supply the electronics and the Slave peripherals,
d the maximum current is limited to 4.5 A, in accordance with the specification,
d the maximum distance is 50 m (164 ft.).
