SINOTIMER ATO-SSR-TH120AA Operating instructions

  • Hello! I'm your chat assistant and I've reviewed the Autonics SR2 / SR3 / SRH2 / SRH3 series SSR catalog. This catalog details 2/3-Phase Solid State Relays with various configurations like detachable or integrated heatsinks. Key features include mounting options, overheat protection, and high heat dissipation. Feel free to ask any questions you have about the specifications, features or applications.
  • What are the available input voltage ranges?
    What are the rated load voltage options?
    What is the purpose of the alarm function?
