QLCP — QuEST Local Control Panel


The QuEST Local Control Panel (QLCP) is a specialized board designed to interface between a custom local control panel (switches and LEDs) and a railway interlocking controller. With 128 switch inputs, 128 LED outputs, RS-232, RS-485, Current Loop, Ethernet (optional), and multiple communication protocols, the QLCP is the perfect LCP solution for any railway signaling application that uses industry standard interlocking controllers. The Ethernet-equipped version (QLCP-NET) provides I/O expansion (up to 512 inputs and 512 outputs), panel duplication for remote houses without the need for additional logic, and a versatile soft panel feature. The QLCP is a drop-in replacement for the Harmon/GETS CLCP board.
