EMAS SSRP1DA025 - 1PH Solid State Relay 25A 24~320V + Heatsink

Complete SSR and heatsink assembly for DIN rail or flush mounting — the 25A SSR pre-fitted with a matched heatsink for continuous-duty use straight out of the box. Driven directly by the pulse output of a PID temperature controller. If you don't need the heatsink, see the standalone SSRP1DA025.

It saves you sourcing and fitting a matched heatsink separately — this comes pre-assembled with the heatsink already attached, ready for DIN rail or flush panel mounting. See the standard SSRP1DA025 if you're fitting your own heatsink or don't need one. Is the heatsink sized correctly for 25A continuous use? Yes — EMAS matches heatsink size to relay rating, so this assembly is suitable for continuous-duty switching at up to 25A without needing to calculate thermal derating yourself. What control signal does it need? 4-32V DC — compatible with most PLC digital outputs directly, and with the pulse output of any PID temperature controller. Can I use this for phase-angle or PWM temperature control? Yes — this is a common choice for driving heating elements from a PID temperature controller's low-voltage output signal. Industry Applications Process heating — PID/PLC-driven temperature control for ovens, extruders, and heated tooling Plastics & packaging machinery — high-cycle switching of heater bands without mechanical contact wear Panel builders — a ready-to-mount assembly that saves selecting and pairing a separate heatsink {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"Why buy this instead of the SSR alone?","acceptedAnswer":{"@type":"Answer","text":"It saves you sourcing and fitting a matched heatsink separately — this comes pre-assembled with the heatsink already attached, ready for DIN rail or flush panel mounting.
