Application of Pick-and-Hold Modules

From GEEPLUS Inc.
 

 

Geeplus's Pick & Hold Modules are designed to work with a wide range of different solenoids, and over a wide range of operating voltage. We recommend the use of a high source voltage to minimise electrical time constant, but modules will work down to 20v supply. Control inputs are opto-isolated so local variations in ground potential should not affect operation.

In distributed systems the pick-and-hold circuit should be situated as close as possible to the driven solenoid. In systems where pick-and-hold is used primarily for force/speed benefits, and where the solenoid is situated close to the control system, it may be more cost-effective to build the P&H unit into the control PCB. This eliminates the need for opto-isolation, and reduces the cost of both opto-isolator and connector costs. Geeplus will license the design of P&H circuit for use in such applications.
