Product Performance
Redundant design
Dual channel architecture: Two independent channels are redundant to each other, and when either channel fails, the other channel automatically takes over to ensure uninterrupted signal acquisition.
Fault diagnosis: Real time monitoring of channel status, feedback of fault information through LED indicator lights and system software.
HART protocol support
Bidirectional communication: Sensor parameters (such as range and damping time) can be remotely configured through the HART protocol, and device diagnostic information (such as sensor drift and line faults) can be read.
Compatibility: Compatible with mainstream HART devices and supports seamless integration with DeltaV systems.
anti-interference ability
Optoelectronic isolation: The input signal is completely isolated from the system bus, effectively preventing ground potential interference and surge impact.
Filtering technology: Built in digital filter to suppress high-frequency noise and ensure signal stability.
flexible configuration
Multi range support: Different signal types (such as 4-20 mA, ± 10 V) can be configured through software to adapt to various industrial sensors.
Hot swappable function: Supports live plugging and unplugging, without the need to shut down during maintenance, reducing system downtime.
