The HK1611 reset time relay is a fully assembled electronic module without enclosure, designed for cyclic control of electrical loads with long ON periods and short periodic OFF intervals. The device operates as an automatic reset timer using a timed OFF cycle.
When power is applied, the relay switches ON and starts counting the preset ON time. After the ON time expires, the relay switches OFF for a fixed period of 1 or 5 minutes, selectable via jumper W2. Once the OFF time expires, the relay switches ON again and the cycle repeats continuously until power is removed.
The ON time is smoothly adjustable from 1 to 24 hours using a trimmer potentiometer. For easier setup, jumper W1 allows the time to be initially adjusted in seconds before switching to hours. All jumper settings must be changed with the power OFF.
LED indicators display power status and relay activity. The module is intended for integration into an enclosure or control panel.
