Questions and answers
Can I use the SSRC-04 on 120 V AC?
The listing gives 220/230 V AC only. For 24 V DC or 120 V AC panels, look at a wide-range relay such as the GEYA GRL8 (AC/DC 24–240 V).
What does 5–50 kΩ sensitivity mean?
The relay senses the liquid through its resistance between the probes. You set the threshold between 5 and 50 kΩ so it responds to your liquid; it works only with conductive liquids.
What can the output switch?
One changeover contact rated 8 A / 2000 VA. Compare it with your pump or contactor coil before wiring.
Where is it used?
The listing names level and discharge control of conductive liquids in tanks in industrial plants and domestic applications.
Can I order several for a project?
Yes. For quantity pricing, request a written quote on our Wholesale & Bulk Orders page.
