Overview

Our FLEX 5000® I/O modules are a rugged and flexible distributed I/O solution, which allows you to choose your I/O to meet your operational needs. FLEX 5000 I/O enhances communication with 1 Gb EtherNet/IP™ connectivity, which offers higher speed and increased bandwidth. To provide flexibility in your network architecture, these modules include 2 copper or 2 fiber ports (SFP) and support for DLR, Star, Linear, and PRP topologies.

What’s New?

Support high availability safety needs

FLEX 5000 EtherNet/IP adapters are enhanced with concurrent communications support. Through concurrent communications, different safety controllers can maintain separate network paths to the same safety I/O module, enabling flexibility and seamless failover. This latest capability supports the new Logix SIS solution with GuardLogix® 5580 controllers, providing a high availability safety solution up to SIL 3 for process applications.

Overview

Reduces system costs and complexity with the flexibility to mix and match standard and safety I/O modules in one platform
Offers true integrated safety with discrete and analog fail-safe I/O modules, TÜV certified up to SIL 3, PLe, Cat. 4, with up to 10 ms safety reaction time
Enhances communication with 1 Gb EtherNet/IP connectivity through copper or fiber, with SFP adapters
Supports a wide range of network topologies: Device Level Ring (DLR), Star, Linear, and Parallel Redundancy Protocol (PRP)
Optimizes footprint with horizontal or vertical installation and interconnect cable extension
Provides direct fiber connection to the adapter with the option to connect up to 16 modules per adapter
Allows users to replace modules while the system is in operation with easy snap-on installation via Removal and Insertion Under Power (RIUP)
Offers flexible and modular capability to support up to 32-channel digital and 8-channel analog input/output
Operates in -40…+70 °C (-40...+158 °F) temperatures and in hazardous areas in Class I, Division 2, Zone 2, Groups A, B, C, D
Allows for use in extreme environments with XT version up to G3 with conformal coating, which helps protect against environmental stresses
Offers the ability of reporting frequency, acceleration and directions with isolated-frequency input modules
Functions as remote I/O modules with ControlLogix® 5580, CompactLogix™ 5380 and CompactLogix 5480 standard controllers and with GuardLogix 5580 and Compact GuardLogix 5380 safety controllers
Supports ControlLogix 5580 controller redundancy (in DLR and PRP network topologies) for high availability applications from Studio 5000 Logix Designer® application version 33 or later
Ideal for Hybrid and Process applications such as emergency shutdown, burner management, turbine control, compressor control, oil and gas auxiliary boilers, high-pressure protection, lighting, and ventilation management
