SZR-MY Series
®
SZR-MY Series general-purpose power relays are designed for a wide
range of applications including power as well as logic control for factory
machines and control panels.
SZR-MY Series relays have a small package design for multiple
application needs. Relays are available in two configurations: DPDT with a
5A load and 4PDT with a 3 A load.
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.
