Product Overview

The 1769-OF8C is a high-density analog output module for Allen-Bradley CompactLogix (1768 and 1769) and MicroLogix 1500 systems. It provides eight high-resolution current output channels, enabling precise control of Final Control Elements (FCE) such as modulating valves and motor drives in automated processes.

Industrial Control Integration

  • Control Elements: Ideal for VFDs, I/P transducers, and valve positioners.

  • Monitoring Hardware: Can drive meters, chart recorders, and data acquisition systems.

  • Configuration: Software-defined channel parameters for safe operation in "Fault" or "Program Mode".

  • PID Control: Provides stable 4–20 mA signals with superior noise immunity.

Mounting and Installation

  • Connection: Integrated bus to controller assembly; local I/O or remote expansion via 1769-AENTR.

  • Orientation: Horizontal or vertical on 35 mm DIN rail.

  • Wiring: Removable terminal block (RTB) for pre-wiring and maintenance.

  • Shielding: Use shielded twisted-pair (STP) cabling; ground shield at one end only to prevent loops.

Common Technical Questions

What is the advantage of 16-bit resolution?
It provides extremely granular control (~0.323 µA per step), critical for sensitive control valves.

Can this module output 0–10V signals?
No. It is strictly current-output. For voltage outputs, use 1769-OF8V or combination modules like 1769-IF4XOF2.
