[ Who We Are ]
The Platform
Specialist.
We’re not a general automation vendor. We’re the company engineers turn to when the standard modules don’t have what the project requires. Whether that’s high-density analog, universal inputs, HART communication, high-speed discrete I/O, or even cross-protocol connectivity.
[ Our Foundation ]
A Rockwell Automation Partnership.
Spectrum Controls became a Rockwell Automation Technology Partner in 1991, one of the earliest in the program’s history. That relationship is the foundation of everything we build.
Our modules use the same backplanes and chassis as standard Rockwell hardware. Drop-in compatible. No programming changes. No I/O tree edits required. The quality and reliability engineers already trust, with more capability built in.

[ What We Make ]
I/O Built for
Real Problems.
Every Spectrum Controls module is designed to solve a specific problem the standard Rockwell catalog doesn’t address. Here’s what that looks like in practice.
01
High Density
Do More in Less Space
A single high-density module replaces multiple low-density ones. This reduces cost, rack space, and power draw. Fewer modules means simpler installation, less wiring, and a cleaner panel.
02
Universal Analog
Maximum Efficiency
Eliminate the need for multiple dedicated input modules. Any channel can be independently configured for voltage, current, thermocouple, resistance, or RTD and in any combination.
03
HART™
Better Communication
The HART® protocol offers enhanced control and communication with devices over existing connections. Our analog + HART I/O combines the best of Spectrum Controls technology with the power of HART.
04
Specialty Modules
Unique Solutions
Some applications don’t call for standard I/O. Our specialty modules which include isolated inputs, thermocouple, RTD, BACnet, high-current relays, and more, provide the exact capability your project requires.
05
InView™ Displays
Plant Floor Visibility
LED message displays visible at up to 450 feet. Dynamic messaging with real-time variables, NEMA-rated enclosures, and superior viewing angles vs LCD.
[ Universal Industrial Gateway ]
More capability. Less cost.
Universal Industrial Gateway connects industrial systems running different protocols without custom programming, proprietary software, or changes to existing PLC logic.
[ Custom I/O ]
Built to spec. Fully licensed.
Spectrum Controls offers full turnkey custom I/O for Rockwell Automation platforms. We handle everything from requirements and design through prototype, certification, and lifecycle support. The result is a module built exactly for your application, fully licensed by Rockwell Automation, and ready to drop into your existing system.
Available for any Rockwell Automation platform.
[ InView Industrial LED Displays ]
Click to configure.
Seen from 450 feet.
InView Displays connect directly to your Allen-Bradley PLC and show live data including output counts, line status, and process values exactly as your system sees them. Browser-based GUI means no programming required. Configure messages, variables, and display logic without writing a line of code.
NEMA-rated enclosures and superior viewing angles vs LCD make InView the display engineers specify when plant floor visibility matters. Visible up to 450 feet.
[ Platform Support ]
10 Platforms. 50+ Modules.
Wherever your system is built, we likely have something for it. Spectrum Controls modules are available across the full range of Rockwell Automation platforms.
