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 NITRA Pneumatic Automation Link (PAL) system is an electro-pneumatic system as well as a field I/O system that can include electrical I/O or pneumatic valves or both. A system can be controlled either by an Ethernet/IP master or direct wiring (for configurations with exclusively pneumatic valves). Assemblies are rated for IP65 and are intended to be machine mounted. Power, I/O and network connections are made via standard quick-disconnect terminations.

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.
