Switch description
The 16 port 10/100-TX with 4 Port High-Power PoE Industrial Switch is a cost-effective solution, which
meets the high reliability requirements demanded by industrial applications, and also supports to operate
in the wide temperature range from -40°C to 75°C. The equipment supports 12 V to 48
V DC
power input
and provides the PoE function with 48
V DC
output for kinds of Powered Devices to receive power as well
as data over an RJ-45 cable.

High-Speed Transmissions
The
wienet
LMS 16-W includes a switch controller that can automatically sense transmission speeds
(10/100 Mbps). The RJ-45 interface can also be auto-detected, so MDI or MDI-X is automatically selected
and a crossover cable is not required. All Ethernet ports have memory buffers that support the store-and-
forward mechanism. This assures that data is properly transmitted.
3.2
Dual Power Input
wienet
LMS 16-W
redundant power input design is with power reserve protection to prevent the switch
device broken by wrong power wiring. When one of the power inputs fails, P-Fail LED will turn on and
send an alarm through a relay output for notifying the user.
3.3
Flexible Mounting
wienet
LMS 16-W
is extremely compact and can be mounted on a DIN-rail or a panel, so it is suitable for
any space-constrained environment.
3.4
Advanced Protection
wienet
LMS 16-W supports up to 3,000 V DC
surge protection for power line, and also supports
6,000 V ESD for Ethernet ports. With these two strong protections, it can secure equipment against unregu-
lated voltage and make systems safer and more reliable. Further,
wienet
LMS 16-W provides currency over-
load protection with a resettable fuse to ensure that the device component won’t be damaged by overload
current.
3.5
Wide Operating Temperature
The operating temperature of the
wienet
LMS 16-W is between -40 ~ 75
℃
. With such a wide range, you
can use the
wienet
LMS 16-W in some of the harshest industrial environments that exist.
