FAULT: The two sets of relay contacts of the 6-pin terminal block connector are used to detect user-configured events. The two wires attached to the Fault contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the Fault circuit will be closed.

STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals.

STEP 2: To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connector.

STEP 3: Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on the EDS-728/828’s top panel.

Wiring the Digital Inputs

The EDS-728/828 has two sets of digital input—DI 1 and DI 2. Each DI comprises two contacts of the 6-pin terminal block connector on EDS’s top panel. The terminal block is also used for EDS’s two DC inputs. Top and front views of one of the terminal block connectors are shown here.

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.
