The Allen-Bradley 1783-EMS08T switch is a managed Ethernet switch. It comes with eight rated 10/100 Mbps RJ45 ports and an optional fiber port. The SFP modules supported by the switch include the 1783-SFP1GSX and 1783-SFP1GLX modules. The 1783-EMS08T switch is part of the Stratix 6000 series. The 1783-EMS08T switch has a rated power input of 250 MA (24 volts DC). The switch supports an input voltage range of 12 to 48 volts DC. The 1783-EMS08T switch has a peak power consumption of 5.8 watts and a peak heat dissipation of 24.6 BTU/ hour at 60 degrees Celsius. The network protocols supported by the switch include TCP/IP, Ethernet/IP, Telnet, Http, DHCP, BOOTP, FTP, IGMP, and SMTP. The 1783-EMS08T switch has 16 port indicators and 3 status indicators.

Ethernet /IP capabilities available on the 1783-EMS08T switch include active connectivity, bandwidth alarm, and port control capabilities. The available switch functions include VLAN, port mirroring, DHCP server, IGMP listening, and IGMP query. The maximum surge current level of the switch is 2.2 amps. The operating and storage temperature ranges of the 1783-EMS08T switch are 32 to 140 degrees Fahrenheit and -40 to 185 degrees Fahrenheit, respectively. The switch is sensitive to ESD (electrostatic discharge). Therefore, safety precautions must be followed when handling the device, including wearing a grounding wrist strap, touching grounded objects to release static electricity, avoiding touching electronic components, and storing the switch in an ESD package when not in use. In hazardous environments, wiring should only be connected when power is off.

The module provides status indicators, including sixteen (16) port indicators for reporting link and activity and three (3) status indicators for reporting overall module operation and mode diagnosis. The module has the functions of MAC ID management, bandwidth alarm, port control, link status, scaling bandwidth information, connection activity, etc.

The 1783-EMS08T supports the expansion and installation of a 1 GB optical transceiver or a single form factor pluggable interface for connecting optical media for faster and noise-resistant communication networks.

For Ethernet interfaces, you are advised to use Class 5e cables that comply with TIA 568-B.1 or Class 5 cables that comply with ISO/IEC 24702. For power connections, the recommended wire size range is 0.33... 3.3 mm2 or 22... 12 AWG, solid or stranded copper wire with an insulation rating of 75 °C or 167 °F or higher with a maximum insulation of 1.2 mm or 3/64 inch. For ground connections, the recommended wire is 3.3 mm2 or 12 AWG solid or stranded copper wire with an insulation class of 75 °C or 167 °F or higher. When connecting the wire to the device's power and ground terminals, the required torque is 1.36 Nm or 12 lb-inch.
