W-Auto type multifunction flashing relay

The ERV-09 is a multi-function, dual-time (ON/OFF) flashing relay designed for applications requiring precise cyclic control between operating and pause times. It is ideal for automation in industrial, commercial, and residential environments.
This device allows independent adjustment of the on ( ON ) and off ( OFF ) times, offering great flexibility in repetitive processes. Its regulation system, using range selectors and fine adjustment, ensures precise configuration even over long intervals.
During operation, the relay automatically alternates between ON and OFF cycles, with visual indication via LEDs, ensuring continuous and reliable control as long as the equipment is powered.
