Questions about this product
- Which model do I pick, DA or AA?
- The DA series takes a 3-32V DC control signal and switches at zero voltage, which suits heaters and temperature controllers. The AA series is AC input with random turn-on for instant switching like lighting or motors. Match the series to whether your controller outputs DC or AC.
- Does this relay need a heatsink?
- Yes, it requires an external heatsink to shed heat under load. Solid state relays run warm because current passes through them constantly. Mount it to a suitable heatsink, especially at the higher current ratings, or it can overheat.
- What load current can these handle?
- The lineup runs from 10A all the way up to 120A, so you size the model to your load. Small heaters use the lower ratings, while big industrial systems need the high end. Load voltage range is typically 24-480V AC.
