Product Overview

The EISW8-100T switching hub is an eight-port unmanaged Ethernet switch that provides 10/100 Mbps performance on all ports to accommodate a range of control devices and workstations commonly found in an automation project. For 10 Mbps legacy devices, the switch will automatically reduce its port-speed accordingly. This low-cost compact unit utilizes a rugged metal enclosure, with DIN-rail and wall mounting installation.

The switch supports plug-and-play operation and requires no configuration. All ports automatically configure their data rate and duplex using the auto-negotiation protocol. Depending on the capability of the link partner, communication is set at 10 or 100 Mbps and at either half- or full-duplex. Each port accommodates either a straight-through or crossover cable using the Auto-MDIX protocol.

The unit is powered from a choice of low-voltages (AC or DC). Redundant power connections are provided for back-up power schemes. LEDs assist in troubleshooting.

Product Details

The EISW8-100T Switch can be used in control panel installations where DIN-rail space is at a premium by requiring a width of only 41 mm of rail space. A metal DIN-rail clip attached to the steel enclosure can survive the toughest installation. In addition, the unit comes equipped with a wall-mount kit for wall-mount installations.

The EISW8-100T has eight Auto-MDIX ports for attaching local devices. Each port has one LED that glows with an established link and flashes with activity which assists in troubleshooting connection issues.

The unit features dual power inputs with wide-ranging voltages (12-48 VDC or 24 VAC). For power redundancy, two DC supplies can be used. A normally open (NO) fault relay contact held closed, opens upon a P1 or P2 power failure. This contact is rated up to 24 VDC at 1A. A wide operating temperature range of –40°C to +75°C make the EISW8 suitable for outdoor applications.

A removable power connector facilitates the servicing of the unit.

The switch is UL Listed for Industrial Control Equipment. It complies with CFR 47 Part 15 Class A and carries the CE Mark. It is UKCA compliant.
