IB200 Isolators
The Isolators are peripherals which can be connected directly to the I-BUS in order to increase
both its extension and performance.
FUNCTIONS
Each isolator has 4 terminals for input connections to the I-BUS and 4 terminals for output
connections to the I-BUS. The functions they provide are:
• Galvanic Isolation, up to 2750V, for the entire BUS between input and output
• regeneration of communication signals, limiting losses caused by the excessive length of
the I-BUS cable
• detection of functional anomalies in direction of the output section and the consequent
isolation of the section concerned
MODELS
3 versions are available:
• IB200/P, model with BUS isolation functions, signal regeneration on BUS, uninsulated
power supply; comes in a plastic enclosure with protection against forced opening.
• IB200/U, model with BUS isolation functions, signal regeneration on BUS, uninsulated
power supply; comes in a plastic enclosure with on-view terminals, without protection
against forced opening and dislodgement.
• IB200/P, model with BUS isolation functions, signal regeneration on BUS, insulated power
supply; and DC/DC converter, comes in a plastic enclosure with protection against forced
opening and dislodgement.
INSOLATOR
The isolator makes it possible to create two groups of peripheral devices by means of the
galvanic isolation of the power supply, the ground and the data channels D and S of each
group. In this way it is possible to separate one group of peripherals connected and powered
directly via the control panel (“group A”) from the group connected to the control panel via
isolator and not powered via the control panel (“group B”).
The protection function is achieved by isolating group B in the event the isolator detects
malfunctions in this group:
- short-circuit between terminals “+” and “-”
- short-circuit between terminals“D” and “+” or “D” and “-”
- short-circuit between terminals“S” and “+” or “S” and “-”
- short-circuit between terminals “D” and “S”
- current absorption higher than 1A between the “+” and “-” terminals (only if the
IB200/A model is used)
Once one of these malfunctions has been detected, the isolator will isolate group B thus
protecting group A. This status will remain active for 10 seconds or until the next control panel
reset operation.
