Technical Specifications

7.3Technical 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 ∝s

-with a frame length of 1500 bytes by approximately 130 ∝s

This means that the more ELS switches the frame passes through, the longer the propagation time.
