Electronics relay designed to switch loads using 6V to 28V AC or DC inputs, the Raraion Relay offers compact control for small projects. That reassurance helps DIYers and technicians complete wiring and automation tasks without fuss. Does the 8A/240Vac (30Vdc) rating match common workshop requirements?

⚡ At a Glance
  • Switching Rating: 8A at 240Vac or 30Vdc
  • Best for: DIY electronics, small automation projects and hobbyist control circuits
  • Not ideal for: Heavy industrial loads or continuous high-current switching

Nominal coil current is 70mA with input compatibility from 6V to 28V AC or DC. Compact dimensions measure 28 x 33 x 53 mm.


Reliable Low-Voltage Control – With 6V to 28V input compatibility

Coil accepts both AC and DC within a 6–28V range, so standard low-voltage supplies can drive the coil directly. Nominal coil current sits at 70mA, giving a predictable load for drivers and controllers.

Direct compatibility with common 12V and 24V systems simplifies wiring and reduces the need for extra interface electronics.

Suitable for Small Mains Loads – Thanks to an 8A contact rating

Contact assembly is rated for 8A at 240Vac and 30Vdc, defining the safe switching envelope for resistive and modest inductive loads. Conservative AC and DC ratings help avoid overload when matching loads.

Capable of switching lighting circuits, small motors and similar workshop loads within the stated limits, when correctly specified.

Easy to Fit in Crowded Projects – With compact 28x33x53mm dimensions

Small rectangular housing minimises panel footprint and eases placement inside tight enclosures or control boxes. Low volume also helps with tidy wiring runs and closer component packing.

Compact size makes it straightforward to include in hobby builds and compact control panels without taking up valuable space.
