Functions

Discrete AC Output:

Provides 8 AC outputs to directly energize devices like magnetic contactors, relays, solenoids, pilot lamps, buzzers, or sirens operating at 120/240 VAC.

Eliminates the need for interposing relays, reducing panel size and wiring complexity.

Grouped Outputs:

Two groups of 4 channels allow operation at different voltage levels within the 85-265 VAC range.

Compatibility:

Works with CompactLogix controllers and MicroLogix 1500.

Supports remote I/O via 1769-ADN (DeviceNet) or 1769-AENTR (EtherNet/IP) adapters.

Diagnostics:

LED indicators per channel for output status monitoring.

Supports diagnostic feedback in Studio 5000 Logix Designer for fault detection.

Installation Flexibility:

Connects to CompactLogix/MicroLogix via a ribbon cable for bus communication.

Compact design (single-width module) for space-constrained applications.

Application Scenarios

Manufacturing: Energizes contactors, relays, or solenoids in assembly lines for automotive, food processing, or electronics.

Process Control: Drives AC-actuated valves or pumps in chemical or pharmaceutical plants.

Material Handling: Controls AC-powered conveyors or sorting systems in warehousing/logistics.

HVAC Systems: Activates AC relays for fans, dampers, or heaters in building automation.

OEM Equipment: Embedded in packaging machines or conveyors requiring AC output control.

System Upgrades: Replaces legacy PLC-5 AC output modules (e.g., 1771-OQ16, 1771-OBD) in migration to CompactLogix systems.
