The DNx-DIO-403 offers high density I/O and flexibility with forty-eight 5V-compatible TTL digital lines configurable as either inputs or outputs in groups of eight-bit ports. The DNA-DIO-403 is compatible with UEI’s “Cube” chassis, the DNR-DIO-403 is designed for use in RACKtangle I/O chassis, and the DNF-DIO-403 is compatible with the DNF series FLATRACK chassis.
All DIO lines are isolated from the rest of the system (they share the same internal ground), and each pin is individually protected against ESD and over voltage, making this layer suitable for the harsh industrial environment use. Guaranteed 2.4V @15 mA output allows direct interfacing of this layer to solid-state relays and other TTL-compatible devices. The DNx-DIO-403 is an excellent digital I/O solution for a wide array of data acquisition and control applications.
The DNx-DIO-403 is a member of UEI's popular Guardian series, which provide high levels of user diagnostics. The DIO-403 board provides voltage monitoring functionality, which can help you reduce mean downtime by protecting the boards from external hardware failures.
