Prince Castle’s second generation of Merlin Timers
feature a new slim design which gives you mounting
flexibility. The 740 Series Timers are designed so
each channel can be programmed independently,
and used simultaneously. The timers are simple to
program and simple to use. The push of a button
activates each channel, and a alarm and multi­colored flashing channel buttons alert the operator
when timing is complete.
