Adding portable, easy-to-install, digital I/O to any Ethernet network—even wirelessly—becomes possible with ACCES I/O’s Model ETH-DIO-48 Ethernet module.

Adding portable, easy-to-install, digital I/O to any Ethernet network—even wirelessly—becomes possible with ACCES I/O’s Model ETH-DIO-48 Ethernet module. The device features 48 or 24 industrial-strength TTL digital I/O lines. Each I/O line is buffered and capable of sourcing 32 mA or sinking 64 mA. Jumper-selected resistors enable user configuration of I/O lines for pull-up (to +5 V dc), pull-down (to ground), or floating, depending on the application. Connections to the board come via two 50-pin IDC-type headers—each header has three 8-bit I/O ports. Each port can be programmed as inputs or outputs. For external circuits, 0.5-A fused +5-V dc power is available at pin 49 of each I/O connector. The board measures 3.550 by 3.775 in., and is housed in a steel powder-coated enclosure with anti-skid bottom. Board size and pre-drilled mounting holes match the PC/104 form factor; as such, it can be integrated into any PC/104-based stack by connecting it to an embedded CPU’s Ethernet port. A DIN rail mounting provision is available for industrial settings.
