Description
Feature
- Designated for delay ON of motors star/delta.
Delay ON Star/Delta Timer Relay GRT8-ST
Function Features -Time t1 (star) : time scale 0.1 s – 10min divided 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.
