For operation, the Electronic-Key is inserted in the Electronic-Key adapter and is held in place by a spring clip.
The power supply for the transponder and the data are transferred contactlessly between the Electronic-Key
adapter and Electronic-Key.

The data carrier in the Electronic-Key is equipped with a combined memory:
116 bytes E
2
PROM (programmable) plus 8 bytes ROM (serial number)
3.1.2 Additional functions of the version EKS FSA
The version EKS
FSA
has two additional semiconductor relay outputs (LA1/LA2 and optionally LB1/LB2) that
are switched off as long as there is no Electronic-Key in the Electronic-Key adapter or if it is not possible to read
the Electronic-Key.
The semiconductor relay outputs are electrically isolated from the device electronics and from each other. Either
AC or DC can be switched.
Each of the outputs is operated with diversity by a dedicated processor that switches off the outputs on removal
of the Electronic-Key (see Figure Block diagram EKS
FSA
).

FSA
By separately evaluating channel LA and channel LB, the EKS
FSA
device can be used in conjunction with a
safe evaluation device in safety-related applications. Integrated voltage monitoring switches off the switching
contacts LA and LB if the power supply drops below 4.5 V or exceeds 5.5 V.
Information!
The switching contacts
FSA
close when the Electronic-Key is inserted, irrespective of the data allocation
on the memory.
