Digital time delay relay is used to provide delay in a circuit

The relay can be configured as Hand reset or Self reset. Self reset mode can be configured as two types. One which does not depends on timer initiator state and one which depends on timer initiator state. The hand reset and self reset time is programmable.
The mode of operation, time delay and self reset time seting is done through tactile switches provided on front and these values will be stored in non-volatile memory.
If mode of operation is selected as hand reset, time delay is initiated by closing "Timer Initiate" terminals. When delay time reaches to zero the output relay operates. Until reset key is pressed the output contacts will not release.
If mode of operation is selected as self reset time which does not depends on timer initiator state, time delay is initiated by closing "Timer Initiate" terminals. When delay time reaches to zero the output relay operates which initiates self reset timer. When self reset timer reaches to zero the output relay will release.
If mode of operation is selected as self reset time which depends on timer initiator state then time delay is initiated by closing "Timer Initiate" terminals. When delay time reaches to zero the output relay operates. Self reset timer is initiated by opening "Timer Initiate" terminals. When self reset time reaches to zero the output relay releases.
In seting mode fast blinking of display indicates mode of operation, slow blinking of display indicates time delay seting and too slow blinking of display indicates self reset time seting. Atier seting changes press reset bution to accept new values.
