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.

PAL - Pneumatic Automation
Link I/O
... New!
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.
- Supports a large amount of I/O - up to 16 discrete input and 16 discrete output modules per system, plus 4 analog output, plus 4 analog temperature
- IP65 rated, machine mountable system decreases design and installation time
- Quick-disconnect electrical and push-to-connect pneumatic connections keep installation clean and simple
- Local expansion allows for several subsystems controlled from one Ethernet/IP node
NITRA PAL System Overview
Protos X™ I/O
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 ultra-compact design makes it perfect for applications where a typical PLC or I/O solution simply would not fit
- Unique interlocking design of the terminals means the data and power buses are carried from module to module and used only when needed
- Four Bus Couplers that utilize Modbus RTU, Modbus TCP and EtherNet/IP protocols
STRIDE Field I/O
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.
- Interfaces remote I/O points to a Modbus TCP network via Ethernet 10/100 Base-T
- Digital inputs, discrete relay and transistor outputs
- Analog current, voltage, resistance & temperature inputs; analog current and voltage outputs
Terminator I/O
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.
- Network interface modules supporting Ethernet, DeviceNET, MODBUS and Koyo remote I/O; some adapters include an on-board RS232 serial port
- Discrete and analog industrial I/O modules with modular terminal bases
- Configuration flexibility by plugging together a network interface module with up to 16 I/O modules. Use local expansion or large I/O drops. No more confining I/O bases.
- AC or DC power supplies. For high power systems, combine multiple supplies on a single I/O set
- Horizontal or vertical DIN rail mounting
