ENDA ATF02-UV is an analog cyclic timer relay, also known as a flasher timer, designed for applications where equipment must switch ON and OFF automatically at repeating time intervals.

The ATF02-UV operates from 90-250V AC, 50/60Hz and mounts directly onto a TH35 DIN rail. Its narrow 18 mm housing makes it suitable for compact industrial control panels.

The ON and OFF periods are adjusted independently:

• ton - relay ON duration
• toff - relay OFF duration

After the OFF period expires, the cycle automatically repeats while the timer remains powered.

Six selectable timing units are available for ON and OFF periods:

• seconds
• 10 seconds
• minutes
• 10 minutes
• hours
• 10 hours

The front scale is adjustable between 0 and 1, allowing the same timer to cover both short and long repeating cycles.

Typical applications include fans, pumps, lubrication systems, solenoid valves, ventilation equipment, contactors, signaling systems, dosing equipment and industrial machinery requiring repetitive ON-OFF operation.
