Product Information
Full details
The R-TECH RT2150 is designed for engineers and hobbyists requiring a robust, PCB-mountable switching solution for higher power devices. Its primary benefit is the combination of a high 30A contact capacity with a compact, sealed footprint, making it ideal for managing power-intensive circuits in tight spaces. A key caveat to keep in mind is that this unit uses a non-latching configuration, meaning it requires continuous current to the 12V DC coil to remain in the closed position.

Extended Product Information
FAQs
Is this relay suitable for AC and DC switching?
Yes, it is a general-purpose relay, but always ensure the voltage and current ratings of your specific load do not exceed the relay's maximum specifications.
Does this relay include a Normally Closed (NC) contact?
No, the RT2150 is configured as an SPST-NO (Single Pole Single Throw, Normally Open) relay only.
Can I use this relay to switch 24V?
The coil is designed for 12V DC, but the contact ratings depend on the specific load type. Check the datasheet to ensure the contact voltage rating matches your circuit requirements.
Is the relay waterproof?
The relay features a fully sealed construction, which protects against dust and moisture, but it is not intended for immersion or extreme submersion applications.
What happens if I lose power to the coil?
Because this is a non-latching relay, it will immediately return to its open (off) state once power to the coil is interrupted.
Troubleshooting
Relay makes a clicking sound but does not switch the load.
Verify the high-power circuit connections and ensure the relay contacts are not pitted or welded from previous over-current events.
Relay fails to actuate.
Check the 12V DC coil voltage with a multimeter to ensure it meets the minimum activation requirement.
Overheating on the PCB traces.
Ensure that the copper traces on your PCB are wide enough to handle the 30A load and consider adding solder reinforcement to the traces.
Pros and Cons
Pros
- High 30A current switching capacity
- Compact and lightweight footprint
- Fully sealed for protection in harsh environments
- Standard 12V DC coil requirement
- Long operational lifespan of 100,000 cycles
Cons
- Non-latching design requires constant coil power
- SPST-NO only (no Normally Closed contact)
- PCB mount requirement limits breadboard prototyping
Setup, Compatibility & Care
When installing the RT2150, ensure your PCB layout accommodates the pin configuration for a 30A-rated device, using heavy-duty traces to prevent overheating at high current loads. The coil terminals require a clean 12V DC source; ensure your control circuitry includes a flyback diode (typically a 1N4007) across the coil terminals to suppress voltage spikes that occur when the relay is de-energized. For maintenance, keep the device in a dry environment and ensure the ambient temperature does not exceed the component's thermal ratings, as excess heat can degrade the sealed housing over time.
