feature
Performance upgrade: The H1B version has optimized diagnostic accuracy and power management, improved electromagnetic interference resistance, and is suitable for more demanding industrial scenarios.
Professional output: 12 relay outputs are compatible with solid-state/electromagnetic relay terminal boards, meeting the driving requirements of actuators and adapting to single redundant scenarios.
Redundancy adaptation: Supports Mark VIe single/double/triple redundancy systems, can be configured redundantly with controllers, improves control output reliability, and adapts to key scenarios such as power plants and petrochemicals.
Strong diagnostic ability: LED real-time display module, communication and channel status, infrared serial port supports local diagnosis, can detect voltage loss, terminal board mismatch and other faults.
Hot swappable support: It can be replaced with power according to system specifications, reducing downtime for maintenance and improving system availability.
Industrial grade stability: multi-layer PCB and surface mount components, resistant to vibration and electromagnetic interference, suitable for harsh industrial environments.
Application scenarios
Gas/steam turbine control system: outputs relay commands for fuel valve control, intake guide vane adjustment, safety interlock action, etc., supporting equipment start stop and protection logic.
Generator set control: Output control signals for circuit breaker closing/opening, excitation system regulation, etc., to ensure the safe operation of power generation equipment.
Petrochemical/Metallurgical Power Equipment: Output compressor, pump unit start stop control, fault alarm and other instructions to achieve process monitoring and automatic control.
Distributed Control System (DCS) Expansion: As a signal interaction node between Mark VIe and on-site actuators, it is suitable for multi device centralized monitoring scenarios.
