Key Features
- SPST-NO (Single Pole Single Throw, Normally Open) configuration for reliable general-purpose switching
- 48 V DC coil voltage with low 200 mW coil power consumption and 11,520 ohm coil resistance
- Compact body dimensions of 20 mm x 10 mm x 10.6 mm for space-efficient PCB integration
- DC coil operate voltage of 33.6 V and release voltage of 4.8 V for deterministic switching thresholds
- Low coil current of 4 mA maximum enabling direct drive from low-power microcontroller outputs
Applications
The RE030048 is well-suited for general-purpose switching in industrial control panels, building automation systems, and 48 V DC power distribution equipment where reliable SPST-NO relay contacts are required. Its low 4 mA coil current draw makes it compatible with microcontroller-driven relay driver circuits in PLC I/O modules and home automation gateways. The compact 20 mm body fits both DIN-rail mounted relay sockets and direct PCB footprints in telecom power systems and battery management units.

Frequently Asked Questions
What coil voltage and current are required to reliably operate the RE030048 relay?
The RE030048 requires a coil operate voltage of 33.6 V DC with a maximum coil current of 4 mA and a nominal coil voltage of 48 V DC. Its 11,520 ohm coil resistance and 200 mW rated coil power allow it to be driven directly from 48 V bus supplies through a simple transistor switch or relay driver IC without a separate power stage.
How does the RE030048 release voltage of 4.8 V DC affect system design for deenergization circuits?
The 4.8 V DC release voltage of RE030048 means the relay will drop out when coil voltage falls below 4.8 V, providing a clear hysteresis band between the 33.6 V operate and 4.8 V release thresholds. This wide hysteresis ensures the relay does not chatter during 48 V bus transients and simplifies deenergization circuit design in battery-backed systems with voltage droop characteristics.
For which 48 V industrial applications is the RE030048 SPST-NO configuration most suitable?
The RE030048 SPST-NO configuration is most suitable for load-switching applications in 48 V telecom rectifier systems, DC motor starters, solenoid valve control panels, and battery management systems where a single normally-open contact is needed to switch loads up to the relay's rated contact current. Its compact 20 mm body also fits space-constrained DIN-rail modules in factory automation systems.
How does the RE030048 body size compare to competing 48 V relays and what PCB mounting footprint does it require?
At 20 mm long by 10 mm wide by 10.6 mm tall, the RE030048 occupies approximately 200 square millimeters of PCB footprint, which is competitive with industry-standard miniature relay packages. Engineers can mount it on standard relay footprints compliant with common PCB relay socket patterns, enabling direct substitution in existing board designs without layout changes.
