May 16, 2014. ACCES I/O Products Inc. has released a new addition to its Ethernet family of products—Model ETH-DIO-48. Designed for compact control and monitoring applications, this product features 48 or 24 industrial-strength TTL digital I/O lines. This Ethernet device suitable for adding portable, easy-to-install digital I/O to any Ethernet network, even wirelessly. The ETH-DIO-48.
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 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.
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, 0.5-A fused +5-VDC power is available at pin 49 of each I/O connector.
Available accessories include a 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, and right angle headers are also available.
The ETH-DIO-48 is designed to be used in rugged industrial environments but is small enough to fit onto any desk or testing station. The board measures 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.
Prices start at $179.
