Description
The VLP is a three terminal device designed specifically to protect the signal inputs to the vehicle detector unit. The device offers protection in the common mode (line to ground) and differential mode (line to line). Any of the three terminals may be used as ground, while the other two serve as inputs for two signal inputs. Specially selected solid state clamping elements have been chosen for the electrical design of the VLP. These elements have been arranged in such a manner as to appear virtually invisible to the detector unit, while offering the maximum surge protection available on the market today.
Installation
The VLP is designed to be installed on the equipment-side of the terminal strip. Simply loosen the three corresponding terminal strip screws and insert the VLP spade lugs under them. Remember, any one of the lugs may be used as ground. This unit is designed to fit either a terminal strip with 9/16” centers or 7/16” centers. Be sure to specify which size when ordering.
* Stud mounting and wire leads also available. See ordering/mounting information.
