Industrial I/O Solutions
Scalable I/O for every industrial application
Emerson offers a broad range of industrial I/O modules built to support reliable, high-performance control across a variety of environments. Whether you’re designing a compact machine or a distributed process system, our I/O solutions provide the flexibility and durability needed to connect devices, collect data and execute control with precision.
From on-machine IP67-rated modules to high-density slice I/O and intrinsically safe options for hazardous areas, the Emerson I/O portfolio makes it easy to tailor your architecture to your application.
- VersaMax I/O
- VersaMax modules offer a cost-effective I/O option for small machines and light process applications. Designed for flexibility, they support both Emerson and third-party controllers.
- RSTi and RSTi-EP Slice I/O
- Compact and modular, these I/O platforms provide high channel density and rapid update rates for distributed systems. Ideal for space-constrained installations where performance and ease of configuration are key.
- RSTi-OM On-Machine I/O
- Built to withstand tough conditions, RSTi-OM modules are IP67-rated for direct installation on equipment. They help reduce wiring complexity and support fast integration with existing field devices.
- RX3i High-Performance I/O
- Designed for demanding applications, RX3i I/O modules offer fast response times, high channel counts and advanced functionality when paired with PACSystems RX3i controllers.
- VersaSafe I/O
- This SIL3-rated safety I/O works with the RX3i platform to deliver distributed machine safety. It simplifies compliance with safety standards and helps protect operators and equipment.
- PAC8000 I/O
- Engineered for process environments, PAC8000 modules include intrinsically safe options for use in hazardous areas. They provide robust performance in locations where reliability is critical.
