Modbus Distributed I/O
Modbus Distributed I/O
SeaI/O Modbus data acquisition modules provide powerful digital, analog, and serial expansion to any computer. Connect to the host via wireless, Ethernet, USB, RS-485, or RS-232 to add the functionality required for your particular application. Multiple units can be daisy chained using convenient pass-through connectors to create a versatile distributed control and monitoring network.
  • eI-O Series (Modbus TCP)eI/O Series (Modbus TCP): Modbus TCP Ethernet digital I/O modules. Remote monitoring of digital I/O from anywhere on your 10/100BaseT Ethernet network.
  • Ethernet I-O (Modbus TCP)Ethernet I/O (Modbus TCP): Compatibility with Modbus TCP allows communication with Modbus-compliant devices over any TCP/IP wired network.
  • Wireless I-O (Modbus TCP)Wireless I/O (Modbus TCP): Compatibility with Modbus TCP allows communication with Modbus-compliant devices over a 802.11b and 802.11g wireless network.
  • Modbus GatewaysModbus Gateways: Modbus Gateways bridge devices on Modbus serial networks (RS-232, RS-422 or RS-485) with those on Modbus TCP networks, allowing seamless integration of any Modbus device.
  • USB I-O (Modbus RTU)USB I/O (Modbus RTU): Control Modbus RTU data acquisition and control devices via a point-to-point USB host connection. Transforming USB-equipped PCs into a powerful industrial controllers.
  • RS-232 I-O (Modbus RTU)RS-232 I/O (Modbus RTU): Add digital and analog I/O to industrial computers. Communicate using industry-standard Modbus RTU protocol over a RS-232 network.
  • RS-485 I-O (Modbus RTU)RS-485 I/O (Modbus RTU): Add digital and analog I/O to industrial computers. Communicate using industry-standard Modbus RTU protocol over a RS-485 network.
  • Modbus I-O Expansion ModulesI/O Expansion Modules: Expansion modules communicate with SeaI/O base modules via RS-485 Modbus RTU. Add additional I/O to an existing SeaI/O Modbus network.
