Allen-Bradley 1746-OW8-SERA Relay Output Module, 8-Point AC/DC

Allen-Bradley 1746-OW8-SERA Relay Output Module

The Allen-Bradley 1746-OW8-SERA is an industrial relay output module designed for dependable switching performance inside SLC 500 control systems. Using eight normally-open mechanical relay contacts, it supports a wide operating range for both AC and DC loads, making it suitable for diverse automation panels and mixed-voltage equipment.

Why It Helps

This module enables direct load switching without the need for external interposing relays, reducing wiring complexity and panel cost. The dual-group architecture allows different voltage categories within one module, while LED status indicators simplify troubleshooting and monitoring during operation.

Key Highlights

• Eight relay outputs provide mechanical isolation and support a wide variety of industrial loads, offering flexibility across AC and DC control applications.

• Two groups of four outputs allow mixed-voltage operation in a single module, improving panel efficiency and reducing hardware requirements.

• Built-in LED indicators provide real-time channel status, aiding rapid diagnostics and minimizing downtime.

• The removable terminal block design simplifies installation and component replacement within existing SLC 500 chassis configurations.

• Rugged design supports demanding industrial environments, including wide temperature ranges and high mechanical durability.

System Compatibility

Designed exclusively for Allen-Bradley SLC 500 systems, including local and remote I/O racks. Fully compatible with all SLC 5/01 through 5/05 processors and standard 1746-series power supplies.

Applications

Ideal for HVAC systems, material handling equipment, assembly lines, SCADA-driven processes, and general-purpose automation tasks requiring mixed AC/DC load control. The module provides long-term reliability and consistent switching performance for demanding industrial environments.
