Your control signal (e.g., from a PLC or microcontroller, typically 3–32V DC) connects to the input side, while the high-voltage AC load (e.g., heater or motor) connects to the output side.

At higher load currents, solid state relays generate heat. It is strongly recommended to mount the HPR-80DA on an appropriately rated aluminum heat sink to ensure stable operation and maximum component longevity.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the FOTEK HPR-80DA compatible with standard temperature controllers?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The DC input on the HPR-80DA is compatible with most standard temperature controllers (such as REX-C100, PID controllers, and similar units) that provide a DC SSR-drive output signal.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does the \\\"DA\\\" in HPR-80DA stand for, and what does it mean for wiring?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The \\\"DA\\\" designation means DC input controlling an AC output.
