Remote monitoring (options).
PSU has been adjusted to operate in a system that requires a remote control of parameters in a
monitoring centre. Implementation of this function is possible upon installation of an additional communication
interface. Data are transmitted using the modbus protocol, and their exchange may be effected through a RS485
bus or through the Ethernet.
ETHERNET network communication.
compliant to IEEE802.3 standard. Ethernet „INTE-C” interface features full galvanic isolation and protection
against surges. It should be mounted inside enclosure of PSU. Upon installation, a possibility of connection to the
Ethernet is enabled.
Communication in Ethernet network is possible due to additional Interface: Ethernet „INTE-C” ,
RS485-ETHERNET network communication.
Communication with the PSUs may be effected on the basis of the RS485 bus via additional „INTR-C”
and „INTRE-C” modules.
In this kind of communication, an additional RS485-TTL „INTR-C” interface must be installed in each PSU,
enabling connection of the PSU to the RS485 bus. A maximum of 247 PSUs may be connected to the bus.
Connection with the Ethernet will be enabled by the RS485-ETHERNET „INTE-C” interface equipped with a
RJ45 socket.
RS485-ETHERNET „INTRE-C” interface is a device used to convert signals between RS485 bus and Wi-Fi
network. For proper operation, unit requires an external power supply in range of 10÷30 V DC e.g. drawn from a
PSU of EN54C-LCD series. Unit is mounted in a hermetic enclosure protecting against adverse environmental
conditions.
