The 620-101293 from Linear is a PRO access gate operators and barrier arms use this common new advanced APeX II controller. The new APeX II control board contains all of the same great features as the original APeX control board, so you won't need to learn how to program and install a completely new system. Like the original APeX board, the APeX II features on-board, low-voltage surge protection for lightning protection. It has plug-in loop detector capability (open, shadow/reset, reversing), as well as pluggable, European-style field wiring connectors. There are LED diagnostic lights and a built-in MegaCode radio that can program up to 40 handheld transmitters and two MGT gate edge transmitters, as well as an integrated three-button station (momentary contact: Open, Close, Stop). To simplify dual gate installation and operation, the APeX II is networkable, and allows accessory devices to be wired to either machine in a dual gate application. The APeX II controller also features automatically resetting fuses, and there are no dipswitches or potentiometers to set. It has a dual seven segment LED display for programming and diagnostics. This controller also brings soft-start/soft-stop capability to OSCO's line of commercial DC battery backup gate operators.
