SZR-LY Series®

SZR-LY Series general-purpose power relays are designed for a wide
range of applications including power as well as logic control for factorymachines and control panels.
SZR-LY Series relays break 10 A loads and are ideal for control panels
that require stable and reliable relays.
One standard and three options are available: LED indicator, internal
surge protection diode, and LED indicator/diode protection. Honeywell’s
global sales and distribution channels ensure a rapid response and excellent
customer service.
