Product Description

The 1769-OA8 is a high-reliability discrete AC output module for Allen-Bradley CompactLogix and MicroLogix 1500 systems. It provides 8 solid-state AC outputs using Triac switching, suitable for motor starters, solenoids, and indicators.

Each channel includes optical isolation to protect backplane logic from electrical noise. The module is compact and DIN-rail mountable, enabling high I/O density without increasing footprint.

Specifications

Specification Details
Output Count 8 discrete outputs (non-isolated)
Voltage Category 120V AC / 240V AC
Operating Voltage 85–265V AC
Operating Frequency 47–63 Hz
Output Type Triac (solid-state AC switching)
Backplane Current Draw 145 mA at 5.1V DC
Max Modules from Power Supply 8
Heat Dissipation 2.12 W total
Signal Delay Turn-on/off within 1/2 AC cycle

Application Notes

  • Triac outputs are suitable for high-cycle AC switching; use surge suppressors with inductive loads.

  • Compact footprint allows I/O expansion without additional space.

FAQ

Does the 1769-OA8 require a separate power supply?
It draws logic power from the 1769 backplane. AC loads must be supplied externally via the module terminals.

Can this module switch DC loads?
No. Triac outputs require AC zero-crossing and will not turn off in DC circuits.
