Here’s a quick summary of the flexitimer’s capabilities. First, it provides
either one or two programmable time periods (Time A and Time B), each of
which can be set independently to any time between one second and 99 minutes
59 seconds – with a resolution of one second. Second, you can set it for just a
single Time A period, or a single (Time A + Time B) sequence, or for multiple Time A or (Time A + Time B) cycles. In fact, there can be anything from 2-99 such cycles. Third, the timer has two internal relays, one of which is activated during the Time A period and the other during Time B. Both relays have a set of mains-rated single pole, double throw (SPDT) contacts, so they can be used either separately or together to switch a wide variety of loads. Finally, the unit operates from 12V DC, which can come from either a battery or a plugpack power supply.
