PRV-330 Relay Controller
The PRV-330 Relay Controller provides mission-critical monitoring for transformer pressure relief devices. It facilitates rapid fault detection and remote signaling to protect high-value power distribution assets.
PRV-330 Specifications
Enclosure
The NEMA 4X and IP66-rated die-cast aluminum housing provides superior corrosion resistance for long-term survival in extreme substation environments.
Data Output
A high-precision 4-20mA analog loop enables continuous real-time pressure monitoring and seamless integration with existing SCADA infrastructure.
Power Supply
The universal 24V-240V AC/DC self-regulating input circuit ensures hardware reliability and simplified power sourcing across various substation platforms.
Signal Relays
Independent SPDT dry contacts offer high-speed, isolated switching for simultaneous local alarm notification and remote fail-safe protection tripping.
Connection
A standard ANSI 4-bolt interface allows for streamlined mechanical mounting and direct bolt-on integration with industry-standard PRD hub assemblies.
