The Y-series I/O board is specifically designed for the ARMxy series of ARM industrial computers with Industrial Embedded Systems. Equipped with its own MCU, they are compatible with EMC and EMI standards. it connects directly to the motherboard of the ARMxy series ARM-Based Devices via pin headers with SPI. The Y-Series I/O board providing a wide range of signal interfaces, including RS485, RS232, DI, DO, AI, AO, IEPE, RTD, TC, CAN, relay outputs, PWM, pulse counting, GPIO, and more. When standard models do not meet specific requirements, it allows for rapid custom development based on user needs without the need for a complete redesign of the ARM industrial computer system.
