Features Separation of ON and OFF: The time settings of delay ON and OFF are separated, and different delay times can be set. The cycle timer relay is mainly set by the knob, the setting accuracy is 10%, and the repetition accuracy is 0.2%. Wide Delay Range: The mini asymmetric loop timer has an ultra-wide delay time range, which can be set from 0.1 seconds to 100 days (10 time ranges). LED Indicator: Delay off time relay to switch different working modes by shorting S-A1. The working status of the relay is indicated by the LED indicator, which is very convenient and fast. Easy Installation: This cycle timer relay is small and lightweight, and can be installed on a 35mm DIN rail. Electrical components that support this standard can be easily clipped on the rail without screws, and maintenance is also very convenient. Wide Range Of Applications: This GRT8-S1 time delay relay has a wide range of applications and is suitable for various periodic delay control occasions, such as providing periodic power-on, lighting control and heating control for circuits.
