Wiring Requirements

WARNING

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your Moxa EDS-728/828.

Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size.

If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

You should also pay attention to the following guidelines:

yUse separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.

yNOTE: Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.

yYou can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

yKeep input wiring and output wiring separated.

yIt is strongly advised that you label wiring to all devices in the system when necessary.

Grounding Moxa EtherDevice Switch

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw, on the side panel of the EDS-728/828, to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.

Wiring the Relay Contact

In this section, we explain the meaning of the two contacts used to connect the alarm contact.

The EDS-728/828 has two sets of relay output—relay 1 and relay 2. Each relay contact consists of the two contacts of the terminal block on the EDS-728/828’s top panel. Refer to the next section for detailed instructions on how to connect the wires to the terminal block connector, and how to attach the terminal block connector to the terminal block receptor.

EDS-828, EDS-728/828 specifications

Moxa Technologies is renowned for its advanced networking solutions, and the EDS-728 and EDS-828 series of Ethernet switches exemplify this commitment. Designed specifically for industrial environments, these switches deliver exceptional performance, reliability, and versatility, making them ideal for various applications, including factory automation, traffic management, and public utilities.

One of the standout features of the EDS-728 and EDS-828 switches is their robust design. They operate efficiently across a wide temperature range from -40°C to 75°C, ensuring reliable performance in harsh conditions. This thermal endurance is complemented by a fanless design, which minimizes potential points of failure, making the switches suitable for environments where dust and vibrations are prevalent.

These switches come equipped with Gigabit Ethernet ports, providing high-speed data transmission crucial for demanding network applications. The EDS-728 features 8 ports, while the EDS-828 offers 24 ports, allowing for flexible network expansion according to user needs. Both models support a range of protocols, including IEEE 802.1Q VLAN for traffic segmentation, which enhances network efficiency and security.

In terms of network resilience, the EDS series utilizes redundant power inputs with a wide voltage range (12 to 48V DC) to prevent any downtime. In addition, they support various redundancy protocols like MRP (Media Redundancy Protocol) and RSTP (Rapid Spanning Tree Protocol), ensuring continuous data flow even in the event of a link failure.

Security is also a key consideration in the design of the EDS-728 and EDS-828. They support advanced security features such as IEEE 802.1X port-based authentication and Access Control Lists (ACLs), safeguarding the network against unauthorized access and potential cyber threats.

The user-friendly interface of these switches facilitates easy configuration and monitoring. Moxa’s MXview network management software enhances this usability, allowing users to visualize their network topology in real-time, manage configurations, and troubleshoot potential issues promptly.

Additionally, the EDS series is compliant with various international safety and electromagnetic compatibility (EMC) standards, ensuring they can be deployed globally without concerns regarding compliance.

Overall, Moxa Technologies’ EDS-728 and EDS-828 series of Ethernet switches are engineered to meet the demanding requirements of industrial networking applications. Their fusion of robust design, advanced features, and security capabilities makes them an excellent choice for organizations in need of reliable and efficient networking solutions.
