The LEE DAN 1601-010 Replacement Control Board is designed for 1601 Series Barrier Gates to provide advanced control and precise gate operations. It features an advanced microprocessor, ports for plug-in open and reverse loop detectors compatible with DKS loop detectors, and selectable loop functions including stop or reverse. Equipped with direct driven limit nuts for accurate gate control, the board also includes an auto-close timer adjustable from 1 to 23 seconds with a timer override to prevent tailgating. Additional functionalities include gate tracker reporting output, a keyed manual release, and a built-in power switch. External obstruction sensing devices are required for operation with these gates.
