The HK88CTB14 cyclic time relay is a ready-to-use device designed to control electrical loads in a repetitive cycle: work - pause - work - pause, and so on.
The device allows independent adjustment of the ON time (load energized) and OFF time (load de-energized). Each interval can be set from 1 to 120 seconds or minutes.
When power is applied, the POWER LED lights up. The relay is activated and the WORK LED turns on (work mode). After the preset work time expires, the relay switches off, the WORK LED turns off, and the pause mode (PAUSE) begins. After the pause time expires, the cycle restarts automatically.
The two time intervals (WORK and PAUSE) are fully independent and are adjusted using separate potentiometers. The selection between seconds or minutes is done via a jumper located on the rear side of the enclosure. The jumper setting must be changed with the power disconnected.
The device can be powered either by AC 220V or DC 12V, but only one supply voltage may be used at a time. The output is a relay with normally open and normally closed contacts, suitable for controlling various electrical loads.
The product is fully assembled, enclosed in a housing, and ready for operation.
