Product Overview

The 1756-OF4 module is an Allen-Bradley ControlLogix analog output module providing four single-ended outputs capable of sourcing either current (4…20 mA) or voltage (-10…+10 V) signals. It installs in a ControlLogix chassis and is used to drive field devices such as actuators, valves, or analog-signal instruments. It supports both integer and IEEE 32-bit floating point data formats with configurable ramping and is suitable for applications requiring mixed current and voltage outputs with precise control and diagnostics. Part number 1756-OF4.

Best Suited For

  • ControlLogix chassis output expansion
  • Mixed current (4-20 mA) and voltage (±10 V) analog control
  • Process control actuator or valve control
  • Applications needing electronic keying and RTB wiring
  • Embedded ramping and signal fault detection
