About RS20-0900MMM2SDAUHH

The RS20-0900MMM2SDAUHH RS20 Unmanaged Ethernet Switch is a Hirschmann DIN Rail-mounted industrial Ethernet network switch designed for low-cost networking switching solutions. The RS20-0900MMM2SDAUHH Switch offers a rugged and compact design that makes it suitable for basic industrial automation applications that require minimal switch management. The RS20-0900MMM2SDAUHH Switch is designed to meet industry standards such as the CE, FCC, c-UL, and c-UL-us standards. It is also designed to provide operational as well as long-term reliability in harsh industrial conditions. The RS20-0900MMM2SDAUHH Switch has an IP 20 ingress protection rating (without a fan), and it is designed to operate within a -40 to 70 degree Celsius ambient temperature range. The RS20-0900MMM2SDAUHH Switch provides users with industrial Ethernet network switching that conforms to the IEEE 802.3 standards. It is used with a twisted pair cable or fiber-optic patch in either the line or star topology.


The Hirschmann RS20-0900MMM2SDAUHH Unmanaged Switch has a total of 9 ports for the switching network (6 standard ports, 2 uplink ports, and 1 multi-mode SC port). The six 10/100 BASE-TX RJ-45 ports support twisted wire connection as well as auto-polarity, auto-crossing, and auto-negotiation capabilities. The operating voltage for the RS20-0900MMM2SDAUHH Switch is supplied redundantly. The RS20-0900MMM2SDAUHH Switch has a SELV voltage range of 12 Volts DC to 48 Volts DC (18 to 30 Volts DC redundant) and a maximum current rating of 496 Amps at 24 Volts DC and 75 milliamps at 48 Volts DC. The RS20-0900MMM2SDAUHH Switch has an approximate shipping weight of 440 grams and dimensions of 74 x 131 x 111 millimeters. The RS20-0900MMM2SDAUHH Switch has one 6-pin plug-in terminal block with spring-clamp terminals for easy and fast wiring. It can be mounted on a DIN Rail simply by snapping it securely into place.
