ISW-621T/ISW-621TS15
1
4-Port 10/100BASE-TX + 2-Port 100BASE-FX Industrial Ethernet
Switch with Wide Operating Temperature (-40~75 degrees C)
Highly Convenient and Feasible Industrial Robust Switch
PLANET has upgraded two models named ISW-621T and ISW-621TS15 for use
in environments with wide-ranging temperatures. The capital ‘T’ (ISW-621T and
ISW-621TS15) shown in the model names means that they can be operated under
a WIDE-TEMPERATURE environment ranging from -40 to 75 degrees C. As we
know the temperatures in many places and countries of the world are lower than
-10 degrees C, these two new models, ISW-621T and ISW-621TS15, are denitely
suitable for Transportation, Manufacturing, Security and Surveillance network
deployments in those harsh environments. The ISW-621T / ISW-621TS15 also
provides a high level of immunity against electromagnetic interference and heavy
electrical surges which are usually found on plant floors or in curb-side traffic
control cabinets.
Flexibly Extendable Distance
They (the ISW-621T and ISW-621TS15) each include four 10/100BASE-TX auto-
negotiation ports and two 100BASE-FX ports. The ISW-621T is equipped with
100BASE-FX multi-mode SC interfaces for transmission distance up to 2km while
the ISW-621TS15 is equipped with 100BASE-FX single-mode SC interfaces for
transmission distance up to 20km. The two 100BASE-FX ports provide more
flexibility for Transportation, Manufacturing, Security and Surveillance when it
comes to distance extension, making the ISW-621T / ISW-621TS15 suitable either
for long distance (ISW-621TS15) or short distance (ISW-621T) network deployment.
Easy Installation and Wide Range of Power Usages
The ISW-621T and ISW-621TS15 are designed with a compact case that allows
either DIN-rail or panel mounting for the efficient usage of cabinet space. It
provides an integrated power supply with a wide range of voltages for worldwide
operation. It also offers dual-redundant, reversible polarity 12V DC to 48V DC
power supply inputs for high availability applications requiring dual or backup power
inputs.
