Siemens 3RP1527-1EM30 Time Delay Relay 0.5-256 SEC 90-240V AC

Siemens 3RP1527-1EM30 is a compact ON-delay timing relay designed for control circuits that require a precise, time-delayed energization of a load. It operates from 90–240 V AC/DC and delivers a timing interval in the range of 0.5–256 seconds, enabling straightforward tailoring of when a circuit closes in response to a control signal. The device provides a single semiconductor normally-open (NO) contact and offers four selectable time ranges, all wired via two screw terminals for simple installation, and it carries the E49 designation on its label. This model is listed as a phased-out product within Siemens’ timing-relay portfolio, with a recommended route for new designs to the 3RP2527-1EW30 series; replacement guidance is documented by Siemens and third-party listings. Typical applications include delaying activation of a contactor coil or other automation loads in machine controls, conveyors, and packaging lines where a defined start-up interval is required, while the solid-state output helps minimize wear on mechanical contacts and simplify wiring in control cabinets.
