WINSTON
General
■ Applications
- Designated for delay ON of motors star/delta.
■Function Features
- Time t1 (star) :
time scale 0.1 s - 10min devided into 4 time ranges
rough time setting by rotary switch.
- Time t2 (delay) :
time scale 0.1 s - 1 s
time setting by potentiometer
- Relay status is indicated by LED.
- 1-MODULE,DIN rail mounting.
