7.3 Technical Specifications of the ELS TP80
Attachments
Attachment of DTEs or Network
Components over Twisted Pair
RJ-45 jacks with MDI-X pinning 10/100
Mbps (half/full duplex)
Electrical Data
Power Supply
24 V dc supply
(18 to 32 V dc)
safety extra-low voltage (SELV)
Power loss at DC 24 V
3.6 W
Current consumption at rated voltage
150 mA
Overcurrent protection at input
PTC resettable fuse (0.6 A / 60 V)
Permitted Cable Lengths
TP Connection
0-10 m with TP cord.
When using the FC Outlet RJ-45, the
following cable lengths are permitted:
100 m for standard cable
85 m for trailing cable
85 m for marine cable
Note
The number of ELS switches connected influences the frame propagation time.
When a frame passes through the ELS, it is delayed by the Store&Forward func-
tion of the switch.
-
with a frame length of 64 bytes by approximately 10
µs
-
with a frame length of 1500 bytes by approximately 130
µs
This means that the more ELS switches the frame passes through, the longer the
propagation time.
Aging Time
5 minutes
