Model SR1-1450R is a genuine Autonics single-phase solid state relay (SR1 series, Single-Phase Solid State Relays (Detachable Heatsink Type)).
Solid-state relays switch AC loads with a semiconductor instead of moving contacts, so they can switch heaters and lamps millions of times silently and without contact wear.

Compatibility and replacement
Order with the full model code SR1-1450R: in the Autonics code the letters and digits after the series select the size, sensing distance or resolution, the output type and the supply, so a different suffix may not fit your wiring.
If the label of the old unit is worn or the model is discontinued, send us a photo and we will confirm the current Autonics equivalent before quoting.
What to check first
