About RS20-1600M2M2SDAU

The RS20-1600M2M2SDAU switch is an unmanaged multi-mode fiber Ethernet switch that has been designed by Hirschmann Automation. This switch comes with 16 ports and one plug-in terminal block that enables the switch to receive voltage so it can work properly. This switch operates with a voltage rating of 12 to 48 Volts DC and a redundant voltage rating of 18 to 30 Volts AC. The Hirschmann Automation RS20-1600M2M2SDAU multi-mode fiber Ethernet switch can be mounted on a DIN Rail. This DIN Rail must be a 35-millimeter DIN Rail according to the DIN EN 60175 standards. When redundant power is used, the power supply unit supplies the device with the higher output voltage, and this voltage is then electrically isolated from the housing. This switch needs to be grounded to minimize the risk of having electromagnetic interference.


Once the Hirschmann Automation RS20-1600M2M2SDAU unmanaged multi-mode fiber Ethernet switch has been mounted on the DIN Rail, the terminal block needs to be added. The terminal block has to be mounted for the voltage supply and for signal contact on the front of the device. Once it has been installed, the voltage supply needs to be connected to the switch via the terminal block. The Hirschmann Automation RS20-1600M2M2SDAU multi-mode fiber Ethernet switch operates at communication distances from 0 to 5000 meters and it has a power output rating of 40.3 BTU per hour. This switch can operate in a temperature range of 0 to 60 degrees Celsius and a non-condensing relative humidity range of 10 to 95 percent. This switch does not have any protective paint on its PCB, but it has an MTBF rating of 40.1 years.
