RS-408 Redundant Ring Ethernet Switch, 8-port 10/100Base-TX

The RSM-408 CR is an 8-port Industrial Ethernet redundant ring switch for 10/100Base-TX networks. Each RJ-45 port negotiates between 10 and 100 Mbps and adapts automatically between MDI and MDI-X wiring, so cabling is simple. Its built-in Cyber-Ring technique allows several switches to form a redundant ring, and a copper link failure is typically detected and recovered within approximately 20 ms.Set-up requires no software. Redundancy mode and maximum recovery time are chosen with DIP switches, and the unit is supplied ready for use once the DIP settings are made. Two DC inputs can be connected to live sources at the same time, so if one fails the other keeps the switch running. A relay output raises a warning when power or network link fails. Modbus/RTU and Modbus/TCP support allows remote monitoring, including through the Modbus OPC Server.The metal housing carries an IP30 rating and is rated for operation from -40 °C to +75 °C. The RSM-408 CR is supplied with the 4SNPNA010021G wall mount kit, and it can also be installed on a DIN rail.ApplicationsRedundant industrial Ethernet ring networksRemote monitoring of switch status over Modbus

The RS-405 CR is a five-port industrial Ethernet switch built for real-time redundant ring networks. Each RJ-45 port negotiates 10 or 100 Mbps automatically and adapts to crossover or straight-through cabling, so it can be installed without software configuration. Ring redundancy is handled by the built-in ICP DAS Cyber-Ring technique, which can recover from a copper link failure in approximately 20 ms.Store-and-forward switching, 2048 MAC addresses and 1 Mbit of frame buffer memory support stable operation in busy control networks. Two isolated DC inputs (+10 ~ +30 VDC) can be connected to live sources at the same time, so the unit keeps running if one supply fails. A relay output signals dual-power or network link failures to the control system.Settings are made with DIP switches for redundancy mode and maximum recovery time. The plastic DIN-rail housing measures 65 x 120 x 99 mm and operates from -40 °C to +75 °C. This model is RoHS compliant.ApplicationsIndustrial control and automation networksRedundant Ethernet ring topologies

RS-405AFCS-T is a 5-port managed-free industrial Ethernet switch for building real-time redundant ring networks. It provides three 10/100Base-TX RJ-45 ports and two 100Base-FX single-mode fibre ports with SC connectors, so a ring can span longer distances than copper alone allows. The built-in Cyber-Ring technique lets several switches form a redundant ring, with recovery from a copper link failure in approximately 20 ms.Configuration is kept simple, with no software setup required. Redundancy mode and maximum recovery time are selected with DIP switches, and the unit accepts two DC power sources connected simultaneously, so one can back up the other. A relay output signals power failure or network link failure. Modbus/RTU and Modbus/TCP remote monitoring is supported, along with a Modbus OPC Server.This ordering code, RS-405AFCS-T CR, is the RoHS-listed version of the single-mode SC fibre model. The unit operates from -30 °C to +75 °C and mounts on a DIN rail in a plastic housing rated IP30.ApplicationsIndustrial control and automation networksRedundant Ethernet ring topologiesLong-distance fibre links within an industrial Ethernet network

The RS-405FC CR is a 5-port Industrial Ethernet switch for building redundant ring networks in industrial control and automation. It combines three shielded RJ-45 10/100Base-TX copper ports with two 100Base-FX multi-mode fibre ports fitted with SC connectors, so a ring can mix copper and fibre runs in a single device.Redundancy is built in through the Cyber-Ring technique, with STP also available as a redundancy strategy. Typical recovery from a copper link failure is approximately 20 ms. The switch needs no software configuration: redundancy mode and maximum recovery time are set with DIP switches on the unit.Two DC inputs accept +10 VDC to +30 VDC and can be connected to live sources at the same time, so one source can back up the other. A relay output signals a power failure or a dual-power or network link fault. The unit is designed for DIN-rail mounting and is rated for operation from 0 °C to +70 °C.ApplicationsIndustrial control and automation networksRedundant Ethernet ring topologies combining copper and multi-mode fibre linksRemote monitoring of ring status over Modbus
