The HK1653 delay ON time relay is a ready-to-use enclosed device designed to control electrical loads with an adjustable delay time.
When power is applied, the preset delay time starts counting. After the time expires, the relay switches ON and remains active until the power supply is removed. Each power-up restarts the timing cycle.
The delay time is smoothly adjustable from 1 to 30 units using a trimmer potentiometer. The time unit (seconds, minutes or hours) is selected via jumpers and must be set while the power is OFF.
The device features LED indicators for power supply and relay status. The timer is fully assembled and housed in a plastic enclosure, ready for immediate use.
