1769-OA8 Allen-Bradley CompactLogix Discrete Output Card

1769-OA8 Allen-Bradley CompactLogix Discrete Output CardAllen Bradley 1769 OA8 CompactLogix 8 Point AC Digital Output Module Product Description The 1769 OA8 (1769 OA8) is a high performance 8 point AC discrete output module engineered for the Allen Bradley CompactLogix and MicroLogix 1500 controller platforms. It provides a robust interface for controlling AC powered field devices such as solenoids, motor starters, and industrial indicator lamps. By utilizing solid state switching technology, the 1769 OA8

Analog Output Range: ±10 V

matching input limits from 95-130 VAC or 190-260 VAC without needing external step-down transformers

operates as a dedicated hardware component for localized machine control and data processing within CompactLogix L3 platforms

Maximum Power Dissipation: 30 W

The TC-CEN021 is a high-performance Ethernet communication interface specifically engineered for the Honeywell Experion PKS Series C architecture

Rated Input Voltage: 24 V DC

allowing maintenance teams to decouple field wiring from the 3500 rack

The configuration for the 3500/15-01-01-00 indicates a standard universal AC setup:

and remote diagnostics

This architecture guarantees an emergency shutdown response in under 20 milliseconds

but the machinery protection monitors continue to function without interruption

Diagnostics: Built-in self-test (BIST)
