Direction can be set by software in 8-signal units. All 48 input channels can be used as interrupt sources, with per-bit enable/disable and edge selection. Key I/O Features 48 bi-directional TTL channels 200 ns max response time 10 kΩ pull-up resistors Output current: IOL = 24 mA / IOH = 15 mA i8255 mode 0 compatible Interrupt & Filter Interrupt on all 48 input channels Bit-selectable enable/disable Rising edge interrupt (LOW→HIGH) Digital filter for noise/chattering Software configurable filter Interrupt signal INTA — All 48 input signals are combined into a single interrupt output. Interrupts are generated on the rising edge (LOW-to-HIGH transition). 02 USB hub & compatibility Features a built-in USB hub function, allowing up to 4 DIO-48DX-USB units to be connected to a single USB port. The 96-pin connector pin assignments are compatible with DIO-48D-PE and DIO-48D2-PCI for easy migration from PCI/PCI Express systems. USB hub – Up to 4 units on one USB port. Compatibility – Same connector shape and pin assignments as DIO-48D-PE. Migration – Easy upgrade from PCI/PCI Express to USB. Self-powered – AC adapter included (5VDC 2.0A). 03 Full specifications Specification Detail I/O format Unisolated TTL-level I/O (positive logic) Number of I/O channels 48 channels (all interrupt-capable) Pull-up resistance 10 kΩ Interrupt 48 inputs combined to INTA, rising edge Response time Within 200 ns Rated output current IOL = 24 mA (Max.) / IOH = 15 mA (Max.)
