Multifunction relay switch

Velleman K8015: Multifunction Relay Switch Kit

Velleman K8015

The Velleman K8015 Mutifunction Relay Switch Kit

With timers, delays, flashers, intervals, and blinkers, this switch kit has it all. The K8015 has 14 different functions that operate using two pre-programmed delays. There is also a learning mode for the delays that allows you to reset time durations anywhere between two seconds and 12 days. The board hosts a transient filter for the relay contacts.

Use to control incandescent lights, halogen lights, fluorescent lights, fans, buzzers, valves, and more. Delay times are stored on an EEPROM to protect from any power failures.

Different modes can be selected by setting on-board DIP postions.


Modes Include: 

Momentary Mode Start/stop Timer Random Timer
Trigger-at-release Timer Non re-triggerable Timer Turn-on Delay
Timer with Early Re-trigger Prevention Turn-off Delay Toggle Mode
 Interval Timer  Blinking Circuit  Blinking Circuit with Timer
