One method of consuming less energy is to apply a voltage to the solenoid coil to provide the necessary force to pull the plunger in, then, when seated, drop the voltage down to a level sufficient to maintain the plunger in a seated position.
The Pick and Hold Module is designed to apply an initial higher voltage to the coil for a pre-determined period of time and then drop the voltage to a pre-determined percentage of the initial value through pulse width modulation to avoid over heating the solenoid coil
The above voltage sequence will be applied to the coil when a voltage (2 to 40 VDC) is applied to the trigger. The trigger voltage can be a secondary voltage (external trigger) or the same voltage used for input voltage (internal trigger).
This is particularly useful when a solenoid requiring a relatively large amount of power needs to be turned on and off with a low power trigger voltage such as a TTL compatible signal.

* Peak time can be made longer in factory on special orders.
** Holding voltage is preset in factory at 30% of input voltage.
This value can be adjusted with the potentiometer on the board.
