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 operating temperature. The capital ‘T’ (ISW-621T and ISW-
621TS15) shown in the model names means that they can support and operate under
WIDE-TEMPERATURE environment ranging from -40 up to 75 degrees C. As we know
the temperature in many places and countries of the world are lower than -10 degrees
C, these two new models, ISW-621T and ISW-621TS15, will be the right products
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 oors or in curb side trafc 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 15km. The two 100Base-FX ports provide more flexibility for
Transportation, Manufacturing, Security and Surveillance with distance extension without
any limitation, 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.
