The Model ETH-DIO-48 Ethernet module 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 permit user configuration of I/O lines for pull-up to +5 Vdc, pull-down to ground, or floating depending on application requirements. Pull-ups are useful for contact monitoring and ensure that there are no erroneous outputs at power-up until the board is initialized by system software. 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 as inputs or outputs. For external circuits, 0.5A fused +5VDC power is available at pin 49 of each I/O connector. Available accessories include a broad range of ribbon cables, screw terminal boards, optically isolated adapters, electromechanical relay boards, and industry standard solid state module racks. Special order items such as conformal coating, custom software, right angle headers, and more, are also available. Prices start at $179.
