Distances of up to 120km can be bridged with the uplinks via single or multimode fibres. The version with optical uplinks additionally has two dual-speed ports (100/1000 BASE-FX) for Fast or Gigabit Ethernet SFP transceivers, which are also available as bidirectional (BIDI) variants and allow data to be transmitted in both directions over a single fibre. The switches can be cascaded as often as required, permitting implementation of decentralised networks with short transmission paths and hence considerably reducing the cost of cabling.īoth switches feature 16 RJ45 ports, which support fast Ethernet (10/100 BASE-TX). These uplinks, which support Gigabit Ethernet, ensure that no bottlenecks develop - even for applications with high data volumes - thus, guaranteeing smooth communication at all times. The 16TX/2DS-S EEC variant offers two optical dual-speed uplinks, which can be equipped with Small Form-factor Pluggable (SFP) transceivers for different optical fibre types. Thanks to the high port density, they also offer an excellent price/performance ratio." Product Manager Sebastian Preiss says: "These two SPIDER switches provide cost-effective solutions for data communication in harsh industrial environments. The switches, which can be mounted on a DIN rail and activated quickly via plug-and-play functionality, are suitable for connecting to the backbone or for networking linear and tree topologies. A second power supply may also be connected to further increase operational reliability. Each RJ45 Fast Ethernet port supports auto-crossing, auto-negotiation, and auto-polarity.The switches have stable metal housing, can withstand extreme heat and cold, and are approved for use in environments with a high explosion risk. The RS20-0800T1T1SDHUHH Managed Switch has a maximum port density of 8 fast Ethernet ports (6 standard RJ45 ports and 2 RJ45 Uplink ports). The RS20-0800T1T1SDHUHH Managed Switch has a 6-pin plug-in type of terminal block for the power connection. The RS20-0800T1T1SDHUHH Managed Switch supports DIN Rail mounting and it comes with an IP 20 industrial ingress protection rating. The RS20-0800T1T1SDHUHH Managed Switch has a fault relay contact that can be used to monitor its functions and enables remote diagnostics. It has an acceptable operating voltage range of 9.6 to 60 Volts DC or 18 to 30 Volts AC. The RS20-0800T1T1SDHUHH Managed Switch has 2 Type D power connectors (P1 and P2) for connecting to redundant AC or DC power supplies. It supports connections to a power supply with a Safety Extra-Low Voltage (SELV) circuit, and its power supply connection is electrically isolated from the switch housing. The RS20-0800T1T1SDHUHH Managed Switch is designed to operate at low voltage.
