Fiber optic networking - PSI-MOS

What are the arguments for it?

Powerful, safe and universal; for all serial bus standards

  • With integrated early warning system: Integrated path diagnostics
  • Top availability due to redundant design
  • Clear advantage: Less wiring - Added functionality with the DIN rail bus


The new dimension of Fiber Optic networking

Enter into a new dimension of fiber optic networking with PSI-MOS. It can't be beat for simplicity and you can use it with all serial communication systems. Particular features PSI-MOS include: Modular stations configuration with hot swap capability and automatic system cross wiring for data and power.

And as to ranges, high-performance FO interfaces open up new dimensions while still using the simplest of connection technology with polymer, HCS and glass fiber. And now for the first time you can have maximum availability by using the PSI-MOS to give you a redundant configuration of your FO networking for each bus system.


Fiber optic networking becomes simple and reliable with high availability

The modular PSI-MOS fiber optic transmission system is suitable for all serial bus standards. You can network your system cost-effectively with either polymer, HCS or glass fiber. Latest equipment technology guarantees a considerable increase in range.

The backplane bus allows easy cross wiring and the integrated path diagnostics show the quality of the fiber optic connection in detail. The system adapts perfectly to all topologies and installation concepts - and the redundant design meets very high reliability demands.


A modular system concept

The FO networking with PSI-MOS devices from Phoenix Contact allows you to configure your optical star coupler to suit your individual requirements. And that applies both to the number of channels and the type of fiber. There are devices for polymer, HCS and glass fiber to choose from.

The integrated backplane makes for convenient installation. Cross wiring for power and data between the modules is not only simple, but automatic when the modules are snapped onto the DIN rail - That saves costly and time-consuming wiring.


With integrated path diagnostics


The FO networking with PSI-MOS devices from Phoenix Contact holds a real novelty in store for top operational reliability: Integrated FO path diagnostics.

Right at startup the LED bargraph shows in detail the signal quality of the FO connection - Time-consuming calibration is therefore superfluous.

And while the system is running, the display constantly provides information on the remaining system reserve. If the performance limit is reached, you receive an early warning via the remote inquiry warning contact before a fault has even occurred.

Integrated path diagnostics



Top availability due to redundant design


For the first time, redundant networking of your bus devices is also possible. The system can thus guarantee the highest possible availability for your plant. The concept comprises FO cabling, FO couplers and the supply voltage. There are two FO paths to each device.

If the quality of the signal falls below that required, the system automatically switches over to the redundant path element without any interruption. The integrated diagnostics switching contact informs you that the redundant path is being used.




Installation plus: The modular DIN rail bus or "T-Bus"


The T branch plug connectors are snapped onto the DIN rail and pushed together. The INTERFACE modules are simply snapped onto this bus.

Hot Swapping

The DIN rail bus or "T-Bus" supplies the modules on the DIN rail with voltage and carries the data between the modules. If a device is ever removed from the DIN rail bus, the connection between the remaining modules remains intact.




Flexible power supply


Matching "Power Packages" from the INTERFACE range can be snapped on at any point to provide the power.

Reliable operation with redundant supply

And of course you can operate more than one power supply unit in parallel. That is the easy way to realize redundant systems.
