FLEX I/O Modules

Our Bulletin 1794 FLEX™ I/O modules offer flexibility for your application with digital, analog, HART analog, and specialty I/O, with 4…32 points per module. You can mix and match digital and analog I/O with mounting and wiring options.

1794 FLEX I/O Modules |  Overview

Overview

  • Modular design provides the flexibility to select the I/O, termination style and network interface independently
  • Supports a wide variety of applications with digital, analog and specialty modules
  • Allows users to replace modules and make cable connections while the system is in operation with easy snap-on installation via Removal and Insertion Under Power (RIUP)
  • FLEX I/O-XT™ extreme environment modules are rated for -20…+70 °C (-4…+158 °F) and are compatible with the ControlLogix-XT™ extreme environment system
  • Conformal coated modules are available
  • Each I/O module requires a terminal base for connection points for I/O wiring

1794 FLEX I/O Digital Modules

  • Cover a wide electrical range
  • Densities range from 8…32 points
  • Isolated inputs or outputs, protected outputs, electronic fusing, or diagnostics available on some modules

1794 FLEX I/O Analog Modules

  • Individually configurable channels
  • Selectable input filters on many modules
  • Single-ended or differential inputs
  • On-board scaling
  • Internal calibration
  • Thermocouple, RTD, and HART (Highway Addressable Remote Transmitter) modules available

1794 FLEX I/O Specialty Modules
