Abstract	The Power Trigger Controller (PTC) of the LHC Beam Dumping System (LBDS) is in charge of the control and supervision of the Power Trigger Units (PTU), which are used to trigger the conduction of the 50 High-Voltage Pulsed Generators (HVPG) of the LBDS kicker magnets. This card is integrated in an Industrial Control System (ICS) and has the double role of controlling the PTU operating mode and monitoring its status, and of supervising the LBDS triggering and re-triggering systems. As part of the LBDS consolidation during the LHC Long Shutdown 2 (LS2), a new PTC card was designed, based on a System-on-Chip (SoC) implemented in an FPGA. The FPGA contains an ARM Cortex-M3 softcore processor and all the required peripherals to communicate with onboard ADCs and DACs (3rd-party IPs or custom-made ones) as well as with an interchangeable fieldbus communication module, allowing the board to be integrated in various types of industrial control networks in view of future evolution. This new architecture is presented together with the advantages in terms of modularity and reusability for future projects.
