Ethernet, Digital I/O, 48-bit, enclosure.

The ETH-DIO-48 was designed for compact control and monitoring applications. The product features 48 industrial strength, high-current TTL digital I/O lines. Connections to the board are made via two industry standard, 50-pin IDC-type headers. Each header has three 8-bit I/O ports designated A, B and C. Each port can be programmed to accept inputs or drive outputs. For external circuits, 0.5A fused +5VDC power is available at pin 49 of each I/O connector. Power is supplied to the card via an included AC/DC regulated 5VDC external power adapter.

This Ethernet device is an ideal solution for adding portable, easy-to-install, digital I/O to any Ethernet network, even wirelessly. The ETH-DIO-48 is excellent for use in applications sensing inputs such as switch closures, TTL, LVTTL, CMOS logic, and is ideal for controlling external relays, driving indicator lights, and more. Applications include home, portable, tablet, laboratory, industrial automation, and embedded OEM.

Each I/O line is buffered by a type 74ABT543A tristate buffer transceiver capable of sourcing 32mA or sinking 64mA. Jumper selected resistors permit user configuration of I/O lines for pull-up (to +5 VDC), pull-down (to ground), or floating depending on the application requirement. Pull-ups are useful for contact monitoring and assure that there are no erroneous outputs at power-up until the board is initialized by system software.

OEM ETH/104 FORM FACTOR

The ETH-DIO-48 was designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board itself measures just 3.550 by 3.775 inches and ships inside a steel powder-coated enclosure with an anti-skid bottom. A DIN rail mounting provision is available for installation in industrial environments. What makes the OEM option unique is that its PCB size and pre-drilled mounting holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most embedded enclosures or systems. The ETH-DIO-48 can be integrated into any PC/104-based stack by simply connecting it to an Ethernet port included with embedded CPU form factors.
