Well Adapted for Any Tough Environment
 
 
Industrial Standards Certified Reliability
 

Industrial environments often involve unknown, hazardous factors that can influence the operation of Ethernet devices. In fact, some of the factors could cause serious disasters or the loss of life and property. Many of MOXAs industrial products have received UL508 and UL60950-1 certifications, which were developed to indicate which industrial control and information technology equipment is suitable for hazardous locations such as maritime environments, or in mining, oil refineries, and other ndustrial settings. In addition, UL/cUL Class 1 Division 2, ATEX IIG3 C1Z2, and DNV and GL maritime type approvals have strict standards for testing which devices can be used safely and reliably in these critical environments.

ABB, a global leader in power and automation technologies, is well known for its high-performance industrial automation solutions. Industrial automation engineers around the world trust ABB to use
only the most stringent testing standards during the certification process. ABB IIT has certified MOXA's products, making MOXA one of only a handful of industrial Ethernet switch manufacturers that have been granted certification under the Industrial IT enabling program.

 
M12/IP67 Solution

The EDS-305-M12 is rated to provide IP67-level protection, which means that the switch will not be affected by tiny dust particles, dirt, water, humidity, or vibration in most industrial environment.

In addition, the EDS-305-M12 is designed to operate reliably in a temperature range of -40 to 75°C.

 
Power-over-Ethernet Solution

MOXA provides a complete range of solutions for any IEEE802.3af PoE compliant unit and Ethernet-enabled device. The EDS-P308 and SPL-24 (PoE Splitter) can be used to simplify wiring in the field, and provide a more versatile environment for installing devices. The devices can be placed up to 328 feet (100 m) from a PSE.

 
Redundant Power Inputs

The EDS-P308/316/308/305 series of unmanaged Ethernet switches provide 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 provide the Ethernet switchs power needs automatically.

 
Relay Output Alarm for Port Breaks, Power Failure

The EDS-P308/316/308/305 series of unmanaged Ethernet switches provide relay contact outputs to warn technicians on the shop floor when the power fails or a port link breaks, so that they can respond quickly with appropriate emergency operation procedures.

 
Broadcast Storm Protection

MOXAs unmanaged Ethernet switches are protected from receiving too many broadcast packets. During normal use, broadcast packets will be forwarded to all ports except the source port. However, unmanaged Ethernet switches will discard broadcast or multicastpackets if the number of those packets exceeds a threshold in a preset period of time. When the preset time period expires, the switch will then resume receiving broadcast or multicast packets until the threshold is reached again.

 
VLAN Tag Packets Transmitted Transparently

The IEEE802.1 standard defines a VLAN tag, which includes TPID Control (Information) with an additional 4 bytes inserted into an untagged Ethernet frame. The EDS-P308/316/308/305/208/205 seriesof switches can transmit and receive these data packets without any change.

 
DC or AC Power Input Options

The EDS-208/205 series of unmanaged Ethernet switches allow users to use either a 24 VDC or 24 VAC power input. The 24 VAC power input is specially designed for applications in the building automationfield where the power input source is often restricted. The EDS- 208/205 series of unmanaged Ethernet switches are low-cost versatile solutions suitable for all industrial applications.
