This 1 Second to 60 Hour Pulse-Pause Relay Timer kit is a general purpose cyclical timer for various automation applications. It provides intermittent (ON-OFF-ON-OFF, etc) operation of external equipment via the high current 16 Amp mains rated onboard relay output.

This timer actives the relay for a user-set Pulse time between 1 second and 60 hours. Once this time period has elapsed, the relay will turn off for a user-set Pause time between 1 second and 60 hours. This process is repeated with the relay turning on and off for the same time periods until power is removed.

Also available as a pre-assembled module (Order Code VM188).

Please note that the product supplied will be the new WST188 version that Velleman has rebranded and now supplies in environmentally friendly packaging. The kit is identical to the original Velleman MK188.
