Technical Specifications of the ELS TP80
Attachment of DTEs or Network
Components over Twisted Pair
Power Supply
Power loss at DC 24 V
Current consumption at rated voltage
Overcurrent protection at input
TP Connection
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.
