5 Port Managed Ethernet Switch

उत्पाद वर्णन

Features Automatic MDI/MDI-X crossover for plug-and-play Each port supports both 10/100 Mbps speed auto negotiation Full duplex IEEE 802.3x and half duplex backpressure flow control Power failure alarm by relay output Store-and-forward architecture Modbus remote monitoring Supports Modbus OPC Server Built-in Cyber-Ring redundant techniqueIntroductionThe MSM-508 is an 8-port Industrial Ethernet (10/100 Base-TX) Layer 2 Managed Switch. MSM-508 supports 10/100M auto negotiation feature and auto MDI/MDI-X function. It can automatically switch the transmission speed (10 Mbps or 100 Mbps) for corresponding connections. The connectors of Ethernet port are shielded RJ-45. The shielded RJ-45 connectors offer a high reliability Ethernet environment for industrial control and automation.It can be managed through RS-232 port via serial console or Ethernet port using telnet or Web browser. In addition, the switch supports a lot of powerful managed functions, such as 802.1Q Tag-based VLAN, Portbased VLAN, 802.1p QoS (Quality of Service), Port Trunking, Spanning Tree, Cable Testing and Port Mirroring. Built-in ICP DAS Cyber-Ring technique that enable multiple switches to be placed into a redundant ring. Typically the switch detects and recovers from a copper link failure within approximately 20 ms for the majority of applications a seamless process. Modbus/TCP, Modbus/RTU and OPC supported, SCADA application can monitor status of Ethernet port with Modbus or OPC protocol.MSM-508 provides two power inputs that can be connected simultaneously to live DC power sources. If one of the power inputs fails, the other live source acts as a backup to automatically support the its power needs. And the relay output facility can deliver warning signal while power or network link failure.LED IndicatorsStatusPower, 10/100M, Link/Act, MasterEthernetPorts8 x RJ-45, 10/100Base-TXStandardsIEEE 802.3, 802.3u and 802.3xProcessing TypeStore & forward, wire speed switchingMAC Table2048Memory Bandwidth3.2 GbpsFrame Buffer Memory1 MbitFlow ControlIEEE 802.3x flow control, back pressure flow controlProtocolVLAN, QoS, Port Trunk, SMTP, TELNETRedundant StrategySTP, Ring (ICP DAS)Isolation1500 Vrms 1 minuteDIP SwitchYes, Normal Run / Repair ModeDigital InputChannels3TypeWet ContactON Voltage Level+19 VDC +30 VDCOFF Voltage Level+11 VDC Max.Digital OutputChannels3TypeOpen CollectorSink/Source (NPN/PNP)Sink (NPN)Load Current30V/100 mA Max.COM PortsPorts1 x RS-232 (Console)1 x RS-485PowerReverse Polarity ProtectionYesInput Range+12 +48 VDC Redundant Dual Inputs (Non-isolated)Redundant Power InputsYesConsumption0.25 A @ 24 VDCAlarm OutputYes,Relay 2 A @ 30 VDCMechanicalCasingMetalDimensions (mm)DIN-rail mounting: 47 x 175 x 129 (W x L x H)Wall mounting: 51 x 190 x 129 (W x L x H)InstallationDIN-rail mounting or wall mountingIngress Protection RatingIP30EnvironmentOperating Temperature-40 C +75 CStorage Temperature-40 C +85 CHumidity10 90% RH, non-condensing
