7. Remote monitoring (options: Ethernet, RS485).
The PSU has been adjusted to operate in a system that requires a remote control of the parameters in a
monitoring centre. Transmitting data concerning PSU status is possible due to an additional, external
communication module responsible for communication in Ethernet or RS485 standard.
Different connection topologies, presented later in this chapter, are only a part of possible communication
schemes. More examples can be found in the manuals dedicated to individual interfaces.
When installing optional features in the power supply unit, power supply current consumption, used
for the calculation of standby time, should be taken into account (see section. 6.4).
7.1 ETHERNET network communication.
Communication in the Ethernet network is possible due to the additional interfaces: Ethernet „INTE” and
RS485-
ETH „INTRE”, according to the IEEE802.3 standard.
The Ethernet „INTE” interface features full galvanic isolation and protection against surges. It should be
mounted inside the enclosure of the PSU.

The RS485-
WiFi „INTRE” interface is a device used to convert signals between the RS485 bus and the Wi-Fi
network
. For proper operation, the unit requires an external power supply in the range of 10÷30 V DC e.g. drawn
from a PSU of the PSBEN series. The unit is mounted in a hermetic enclosure protecting against adverse
environmental conditions.
