Key Technical Specifications

Product Features

• High Reliability & Redundancy: Adopts a dual-channel redundant design, which enables automatic switching in case of faults to ensure uninterrupted system operation.
• Safety Certification: Complies with SIL 3 requirements, making it suitable for safety-critical systems.
• Multiple I/O Expansion Options: Supports a variety of input/output modules, allowing flexible connection to on-site devices such as sensors and actuators.
• Easy Integration: Compatible with the DeltaV SIS platform, providing standardized communication protocols and configuration tools.
• Strong Environmental Adaptability: Features a wide operating temperature range, shock resistance, and vibration resistance, meeting the harsh conditions of industrial sites.
• Self-Diagnosis & Hot-Swapping: Real-time monitoring of its own status during operation; supports on-line module replacement without interrupting the system.

Structure & Composition

• Host Unit: Houses the CPU, memory, power supply circuit, and communication interfaces.
• I/O Expansion Slots: Used for inserting different types of terminal modules (e.g., KJ2201X1-BA1 terminal), enabling signal acquisition and output.
• Redundant Channels: Two sets of independent processing paths that serve as backups for each other.
• Heat Dissipation & Protection Structure: Features a metal housing with DIN rail mounting, providing basic protection (IP20) and facilitating heat dissipation.

Typical Application Fields

• Safety control for petrochemical processes
• Safety systems for natural gas transmission, distribution, and compression stations
• Protection and automation of power systems
• Machine safety interlocking in manufacturing industries
• Safety monitoring in high-risk industries such as mining, rail transit, and nuclear energy

Key Points for Installation & Maintenance

1. Mounting Method: Adopt standard 19-inch DIN rail mounting to ensure the chassis is fixed securely.
2. Wiring: Use corresponding terminal modules (e.g., KJ2201X1-BA1) for on-site signal access, and follow the wiring specifications of the IEC 61850/ISA-S71.04 standards.
3. Power Check: Verify that the 24 V DC power supply is stable and the current does not exceed the rated value.
4. Environmental Check: Ensure the operating environment’s temperature and humidity are within the specified range, and prevent the intrusion of dust and corrosive gases.
5. Self-Diagnosis: The system will automatically perform a self-check after startup and display fault codes; regularly check the diagnostic logs via the DeltaV SIS software.
6. Redundancy Test: Conduct regular redundancy switching drills to verify the dual-channel switching function.
7. Hot-Swapping: I/O modules can be replaced while the system is running, but it is necessary to confirm that the module status has been updated in the software.
