What is a sequential timer?
A sequential timer, also referred to as a sequencer or sequence timer, will energize and de-energize multiple outputs over a period of time. The amount of time before each output is energized and the amount of time the output remains energized is variable. The outputs may be energized one at a time in order. For mechanical relay applications, the relay contacts of the first relay will close. Then, after a set amount of time, the first relay's contacts will open and the second relay's contacts will close.
Programming a Sequential Timer
Phenix offers a full line of programmable multi-output timers, up to 10 outputs. Any multi-output timer device may be programmed for sequential timing applications. The Phenix Programmer Software provides an easy interface for setting up a sequential timer.
Sequential Timer Program Sample
The sample program above demonstrates the basic design for a 4 output sequential timer. Selecting the "On Power" event will start the sequence when the timer is powered. The first command in the sequence will set the first output to ON and initiates a 2 second interval. After the 2 second ON interval expires, the next command in the list is executed. The timer sets the first output to OFF, the second output to ON, and then another 2 second interval is initiated. This process is continued for each command in the sequence until each of the 4 outputs has been activated for 2 seconds. When the last command interval expires, the timer will loop back to the top command and automatically repeat the sequence. The sequence will be repeated until the power is removed from the timer.
Two to 10 outputs devices are available over a full range of operating voltages and switching current. For the list of available timers, please see Phenix Timer Catalog.
The timer program memory is stored non-volatile memory in the timer. The memory will persist through power outage. Timer devices may be ordered preloaded with any delay time desired or changed at any time using Phenix Infrared Programming
