Standards ČSN EN 45545-2 ČSN EN 45545-2 ČSN EN 45545-2
ČSN EN 50155 ČSN EN 50155 ČSN EN 50155
50155, as well as the fire protection of railway vehicles accor-
ding to ČSN EN 45545-2 and can also be used to ensure the sa-
fety of machinery according to ČSN EN 60204-1.
The devices meet the requirements of EMC tests according to
EN 50121-3-2 and EN 61326-2-4 and the limitation of haza-
rdous substances according to EN 50581.
For all devices, data can be read using Modbus/RTU.
For applications where non-sinusoidal voltages in the DC to
15 Hz frequency range can also be expected, we recommend
using the top of the range isoRW685.
This range of devices allows connection and display of data via
a web browser, as well as the ability to set individual alarm pa-
rameters or read data via a Modbus/TCP interface.
