The Ether I/O 24R is a UDP/IP controlled Digital Input/Output module. The module features three 8-bit ports with 5V level signal lines. Each of the 24 lines can be independently programmed as either an input or output via the 10Mbps Ethernet interface.

The module connects to any Ethernet network supporting the TCP/IP protocol suite and can communicate with any point on that network. By connecting to an internet router, it can communicate to any device which is connected to the internet.

24 Digital I/O over Ethernet Control Board Features

• Supports ARP, BOOTP, DHCP, ICMP and UDP/IP protocols
• Programmable, port number, subnet mask and gateway address
• Programmable fixed IP or Dynamic IP assignment from a DHCP server
• Jumper to force fixed IP address of 192.168.0.10
• Sends multiple bytes via SPI on PORT A
• Link Status LED built into the RJ45 connector
• 10BaseT Ethernet interfaced with RJ-45 connector
• 24 independent programmable signal lines with configurable CMOS, TTL or Schmitt Trigger thresholds and programmable pull-ups per line
• Easy connection by three 10 way box headers to suit low cost, standard IDC or crimp connectors
• Integrated Switch Mode Voltage regulator which allows power from any 8-32V DC power source
• 5V, 500mA user output to power external interface boards or sensors
• Compact module measures only 72mm x 72mm
• Advanced configuration allows the modules to automatically scan the input ports and transmit changes directly to another ETHER I/O 24 module without host connection or to any internet port by router connection
• On board EEPROM allows all ports to power up in a user programmable state
• Small packet size and connectionless protocol allows real time sensing and control
• Can be connected to a wireless network gateway or access point for wireless operation
• Low Power consumption only 1.1W fully operational applications
• Home or industrial automation
• Digital input and output from any networked PC
• Remote data acquisition and/or alarm monitoring by network or internet
• PC controlled machines and distributed machine I/O
• Remote lighting / Power control and/or monitoring
