Naval supervision relay RSN

Categories:
Description: The RSN supervision relay is an equipment intended for the protection of the generating sets usually employed on board. It can be used both in naval and industrial installations. It is prepared to be connected to a centralised control point, by using a RS 485 bus, which allows both the configuration and the sending of operation records. It is also possible to set the relays through the potentiometers on it’s front and through it’s USB port. It is possible to configure the equipment through the USB port, without the need for auxiliary voltage. The design of the equipment ensures high precision, as well as allowing huge flexibility in terms of selecting the output and up to to two digital inputs. In addition to precisión, special care has been taken to ensure robustness and reliability, as well as high electromagnetic immunity for use in harsh industrial environments with high insulation characteristics.
