Product description

The Siemens 3RP2555-1AW30 is an electronic flasher relay with an asymmetrical output function. It provides 1 change-over contact and features 2x7 time ranges, allowing for extensive timing flexibility from 0.05 seconds up to 100 hours. This relay operates on a wide voltage range of 12-240V AC/DC at 50/60 Hz AC and includes an LED for status indication. It utilizes screw terminals for secure connections.

This flasher relay is ideal for applications requiring cyclical or intermittent operation, such as traffic signals, warning lights, automated testing equipment, and intermittent lubrication systems. Its long time range capabilities make it suitable for processes requiring extended on/off cycles.
