Asymmetric Cycler Timer Relay WTT8-S1

Used for cyclic delay control scenarios, periodically powering on a certain electrical circuit, lighting control,and heatingcontrol.

Available in AC/DC 12V-240V ultra wide working voltage specifications.

Product Detail

Function choice is done by an external jumper of terminals S-A1.
Time scale 0.1 s – 100 days devided into 10 time ranges:(0.1 s – 1 s / 1 s – 10 s / 0.1 min – 1 min / 1 min – 10 min / 0.1 hrs – 1 h / 1 hrs – 10 hrs / 0.1 day – 1 day /1 day – 10 days /3 days – 30 days / 10 days – 100 days).
Relay status is indicated by LED.
1-MODULE, DIN rail mounting.
