Technical Specifications DC control input, AC load output. Rated control input voltage 24 V DC, rated output load current 12 A. Output voltage range 24‑280 V AC. Operating temperature ‑30 ℃ to +80 ℃, storage temperature ‑40 ℃ to +85 ℃. Protection grade IP20.
Functional Features Non‑contact electronic switching without mechanical contact wear. Low switching noise. Fast switching response speed. Built‑in over‑heat and over‑current protection mechanism. Compact DIN‑rail installation structure.
Application Scenarios Industrial automation control cabinet, packaging machinery, heating equipment and light‑load actuator control. Used for frequent switching occasions replacing mechanical relays.
Performance Parameters Long service life for frequent switching operation. Zero‑crossing switching characteristic reduces electrical surge. Protection circuit responds rapidly under overload condition.
Material Composition Flame‑retardant engineering plastic housing. Semiconductor power switching chip, trigger and protection circuit board. DIN‑rail metal spring clip. Screw‑type input and output terminals.
Structural Characteristics Compact DIN‑rail housing structure. Equipped with control input terminals and load output terminals. Built‑in spring clip for DIN‑rail mounting. Weight approximately 0.13 kilogram.
Working Principle When control input receives 24 V DC signal, internal trigger circuit activates semiconductor power chip. Load circuit turns on to supply power to field equipment. When control signal disappears, semiconductor chip cuts off load current. Internal temperature and current monitoring circuit triggers protection action under abnormal working condition.
Installation Requirements Mount 1SAR700012R0005 onto standard DIN rail. Tighten control input and load output wiring terminals strictly according to load current requirement. Ensure good natural ventilation and heat‑dissipation space around relay. Switch on power and verify switching function.
Usage Notes Do not exceed rated load current and voltage parameter. Reserve sufficient heat‑dissipation space during installation. Avoid long‑term operation under over‑load condition. Check terminal fastening condition in periodic maintenance.
