Overview

The FLEX I/O™ terminal base is an essential component for connecting I/O modules in industrial automation systems. It attaches to the DIN rail next to the I/O adapter and provides terminal connection points for I/O wiring, creating a backplane when modules are connected together. Available with cage, screw, or spring-clamp terminations, the terminal base is designed to work seamlessly with various FLEX I/O modules. Optional accessories are available depending on the I/O module and system setup.

Key Features

• Compact Design: Wire directly from the sensor to the terminal base, eliminating the need for a terminal strip, saving space.
• High Functionality: Supports 4- to 32-point modules with functionality comparable to larger rack-based I/O systems.
• Enhanced Productivity: Simplified configuration and setup with built-in wizards to speed up engineering and installation processes.
• Reduced Downtime: Features Removal and Insertion Under Power (RIUP) and built-in diagnostics to minimize system downtime.
• Extensive Options: Over 90 catalogue numbers, including specialty modules, to meet a wide range of application requirements.
• Harsh Environment Support: Conformal coated and extreme environment-rated modules are available for challenging operational conditions (contact NHP for more details).
• Network Flexibility: Compatible with EtherNet/IP™, ControlNet™, DeviceNet™, and PROFIBUS DP for flexible network integration.
• Improved Operations: HART analog modules allow seamless data transfer to asset management software or controllers for improved plant operations.
