Version
DEHNsignal E 3: Receiver module for optical transmission for selective operating state indication / centralised fault indication of three coordinated DEHNbloc Maxi S and, where appropriate, DEHNgap Maxi S lightning current arresters in five-wire systems
Details
The DEHNsignal E 3 receiver module for optical transmission transmits remote signals of DEHNbloc Maxi S and DEHNgap Maxi S surge protective devices.
The DEHNsignal E 3 receiver module is particularly adapted to the place of installation of the coordinated DEHNbloc Maxi S and DEHNgap Maxi S surge protective devices.
Three DEHNbloc Maxi S arresters and, if necessary, the N-PE protective circuit can be remotely monitored by the receiver module via optical fibre cables.
Considering the special installation environment of surge protective devices in a switchgear installation, communication via optical fibre cable between the protective devices and the DEHNsignal E 3 receiver module is a considerable safety benefit.
The operating states of the individual arresters are transmitted to the DEHNsignal E 3 receiver module in the form of an optical signal via EMC-resistant plastic optical fibre cables. The optical signals are evaluated in the DEHNsignal E 3 receiver module and are converted into an electrical signal. The operating states can be directly read at the DEHNsignal E 3 receiver module or can be transmitted via a floating changeover contact. The DEHNsignal E 3 receiver module features a green indicator light to check its operating state. In addition to the operating state indication, the three red indicator lights of the selective operating state indication indicate the operating states of the assigned protective devices. The receiver module signals if a protective device of a phase fails. The surge protective devices and the DEHNsignal E 3 receiver module can be easily connected via optical fibre cable by means of the accessory parts described.
