AVT1459 B

Extremely simple but functional timing system that allows control of any devices with intermittent operation - it is used to cyclically turn on and off the load. The 'heart' of the timer is the immortal and legendary cube of the NE555. A typical astable system was used - the generator generates constant time pulses determined by the combination of capacitor and resistors. A relay was used as the control element. This guarantees full separation from the 230V grid.

The device is particularly recommended where it is necessary to periodically switch on / off the electrical device

Selected parameters:

• smooth adjustment of the break time between attachments
• smooth adjustment of switching on and off times
• the switch-on time range is 0.5 - 8 s
• OFF time range 0.5 - 60 s
• work signaling - LED diode
• executive element - relay
• contact load 8A / 230Vac
• power supply - 12-15 Vdc
• dimensions of the tile 47x35mm
• in the set a printed circuit board, a set of elements and documentation
