Autonics SR1-4440: single-phase solid state relay from the Autonics SR1 range (Single-Phase Solid State Relays (Detachable Heatsink Type)).
SSRs are standard in temperature control of heaters (plastic machines, ovens, packaging sealers), driven directly by the voltage output of a temperature controller.

Compatibility and replacement
Order with the full model code SR1-4440: 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.
Compare the old unit with the technical data above (taken from the official Autonics data sheet); if anything differs, send us a photo and we will check it.
What to check first
