With the fibre optic I/O system FOB, up to 8 digital signals – such as switching, control, clock, synchronisation and fault signals – or up to 4 analogue measured values can be transmitted unidirectionally. Transmitters and receivers are available for different types of fibre optic cables (singlemode or multimode). Each system requires one transmitter and one receiver. Signals are transmitted via fibre optic cables, ensuring fast, interference-free data transmission even in harsh industrial environments or in the field.
Complete potential separation reliably prevents problems that can arise from potential carryover, interference voltages or similar influences. The system works on the plug-and-play principle – no software installation, parameterisation or adjustment is required, making installation and commissioning particularly easy and efficient.
The input signals are recorded and transmitted 1:1 to the remote station. The receiver continuously monitors the reception of the valid transmission protocol and has an integrated relay contact which, in addition to optical signalling via a red LED, can also be used as a fault signal contact. In the event of a fault, the normally open contact opens, making the system self-securing and ensuring that the fault message is reliably retained even in the event of a power failure.
