Core Functions
16-Channel High-Voltage Signal Acquisition: Converts 240V AC field switch signals into controller-recognizable digital quantities, suitable for high-voltage equipment status monitoring scenarios.
Channel-Level Isolation and Interference Suppression: 1500V AC opto-isolation suppresses electromagnetic interference in industrial environments, ensuring signal acquisition accuracy.
Fault Diagnosis and Alarm: Real-time monitoring of channel faults and signal failures, with system alarm prompts for quick problem location.
Hot-Swap and Easy Maintenance: Supports online hot-swapping, adaptable to standard terminal bases, reducing downtime for maintenance.
Harsh Environment Adaptability: Coated protective design withstands high and low temperatures and humid/dusty environments, suitable for harsh operating conditions in petrochemical, power, and other industries.
Functions, Applications, and Typical Scenarios
Power Energy High-Voltage Monitoring: Acquires auxiliary contact signals from high-voltage circuit breakers, disconnect switches, and grounding switches, monitoring switch opening and closing status to provide data for power grid control and safety interlocking.
Petrochemical High-Voltage Systems: Monitors the status contacts of high-voltage pipeline emergency shut-off valves and high-voltage pump sets, working with Safety Instrumented Systems (SIS) to achieve high-voltage equipment fault alarms and safe shutdown.
Metallurgy and Heavy Industry: Collects status signals from high-voltage motors, transformers, and high-voltage control cabinets for equipment start-stop interlocking, overload protection, and remote monitoring.
Rail Transit High-Voltage Equipment: Monitors the status of contact network disconnect switches and high-voltage circuit breakers to ensure safe operation and rapid fault response of the power supply system.
Building and Industrial Power Distribution: Collects the status of 240V AC circuit breakers in distribution cabinets to achieve remote monitoring, fault location, and safety alarms for the power distribution system.
