III. Product Features

High Reliability and Safety

• Adopts advanced control technology, supporting the selection of electromagnetic relays and solid-state relays to adapt to different load requirements.
• Complies with the IEC 61508 standard, suitable for hazardous areas (Class 1, Zone 1).
• Built-in soft-start and fast current-limiting functions to prevent faults caused by power fluctuations.

Flexible Communication and Diagnostics

• Supports multiple communication protocols (such as Modbus, Profibus-DP) and enables high-speed data exchange via Ethernet.
• Equipped with LED status indicators and an infrared port for convenient local monitoring and fault troubleshooting.

Modular Design

• Composed of a processor board and an acquisition board, supporting hot-swap installation for easy maintenance.
• Can be seamlessly integrated with other modules of the Mark VIe system (such as input modules and power modules).

IV. Structure and Composition

Core Components

• Processor Board: Shared among all Mark VIe distributed I/O modules, responsible for data processing and logic control.
• Acquisition Board: Specifically designed for discrete outputs, directly connecting to the terminal board and controlling relays.

Connection Methods

• Input End: Connected to the control network via dual RJ45 Ethernet interfaces, powered by a 3-pin power interface.
• Output End: Docked with the terminal board through a DC-37 pin connector, supporting 12 relay outputs.

V. Application Fields

Industrial Automation

• Widely used in gas turbine control and process automation in industries such as power plants, petroleum refining, and water treatment.
• Supports integration with PLC and DCS systems to achieve complex logic control.

Safety and Redundancy Control

• In hazardous areas (such as chemical plants), it is used in conjunction with the Mark VIeS safety system to meet TMR (Triple Modular Redundancy) requirements.

Energy Efficiency

• High-efficiency design (>95%) reduces energy consumption, suitable for motor drive and energy-saving renovation projects.

VI. Installation and Maintenance

Installation Steps

• Install the module on a DIN rail or a dedicated base to ensure electrical isolation and mechanical fixation.
• Physically connect to the terminal board via the DC-37 connector, and wiring must comply with the 24V DC standard.

Maintenance and Diagnostics

• Use LED indicators to monitor the module status in real-time (such as power supply and output activation signals).
• Perform local configuration and fault troubleshooting through the infrared port, supporting remote diagnostics.
• Regularly check the relay contacts and connector contact conditions to avoid faults caused by oxidation or loosening.
