For controller installations where end devices are located long distances away, field I/O or distributed I/O systems can greatly improve system efficiency and reduce wiring costs. Localizing field terminations at the machine or device being monitored/controlled allows for easier installations/modifications, shorter wire runs, and faster troubleshooting.
The Protos X "Xpansion" I/O System ...
using serial Modbus RTU (RS-485) or Ethernet Modbus TCP or Ethernet/IP communication protocols
The Protos X compact, modular field I/O system
allows a user to install remote field I/O devices without having to invest in another controller. The unique slim design and low cost of the Protos X I/O makes it the most practical distributed I/O available today. The ultra-slender form factor makes it easy to install on or near machine or application components, saving time and excess field wiring and speeding up troubleshooting.
The Stride Field I/O family of modules provides a simple and economical means to connect inputs and outputs to a Modbus TCP communications network. Each module operates as a standalone Modbus TCP server, and can be configured via a built-in web server. Analog input, output and thermocouple modules have fully isolated or isolated-in-pairs channels for noise-sensitive applications.
Terminator Field I/O provides you with an industrial I/O system with remote I/O, distributed I/O and digital I/O module capabilities. It combines the I/O points with their field terminations into a modular package to save panel space and money. With Terminator I/O, you can use distributed I/O nodes close to field devices for faster and more efficient wiring and troubleshooting.
