Honeywell SZR-MY/LY series general-purpose power relays are suitable for a variety of application environments, including power, factory automation logic control, various mechanical equipment control, and various control cabinets, control boxes, etc. The SZR series power relay has a compact design, which is suitable for various application occasions. MY series two-way type can carry a load current of 5A, four-pole contact type can withstand a current of 3A, LY series can carry a current of 10A. There are three optional additional functions: LED indication, diode protection, and simultaneous LED indication and diode protection.
The SZR-MY/LY series from Honeywell are compact power relays designed for a wide range of industrial applications such as automation logic control, machine control panels, and control cabinets. They offer options with different contact materials (pure silver, silver‑plated, silver‑alloy) and ratings up to 10 A.
The leaflet includes detailed selection tables, electrical and mechanical ratings, environmental limits, and certification information (UL, CE, CSA). It also describes mounting options, terminal types, and optional features like LED indicators and diode protection. This manual is written in Chinese.
