Features 【Adjustable】Adjustable cycle timer, its on and off timer is separated, so you can set different delay times. 【Time Setting】The cycle timer relay has an ultra-wide delay time range, adjustable from 0.1 sec to 100 days (10 options). After A1 is short-circuited to power on with S, 15-18 will be disconnected first by t2 time, then closed by t1 time, then disconnected by t2 time. 【Different Modes】Electronic on/off relay can switch to different operating modes by short-circuiting S-A1. The working status of the relay is indicated by LEDs, and the relay can control 2 groups of loads. Starting - Disconnection - Permanent Cycle 【Rail mounting】In case of small size, this relay can be mounted on 35 mm DIN rail. 【General purpose】GRT8-S2 asymmetric small cycle timer is used for cycle delay control to provide cyclic power, lighting control and heating control for circuits.
