Modicon AEG B814 -108 Selectable N.O./N.C. Relay Output AS-B814-108

Modicon AEG B814-108 Selectable N.O./N.C. Relay Output Module (AS-B814-108)

The Modicon AEG B814-108 is an 8-point relay output module designed to interface with programmable logic controllers (PLCs) in industrial automation systems. This module effectively converts PLC signals into eight independent relay outputs, each capable of handling various loads such as relays, pilot lamps, motor starters, and solenoids.

Key Features

• Configurable Relay Outputs: Each of the eight outputs can be user-configured for either normally open (N.O.) or normally closed (N.C.) operation, providing flexibility to meet specific application requirements.
• High Load Capacity: Each output supports loads up to 5.0 A, accommodating a wide range of industrial devices.
• Electrical Isolation: Outputs are electrically isolated from the I/O bus and from each other, ensuring reliable operation and protection against electrical interference.
• Surge Current Tolerance: Designed to withstand high surge currents typical of industrial loads, enhancing durability and performance.

Specifications

• Output Points: 8
• Load Capacity per Output: 5.0 A
• Operating Voltage: 115V AC
• Module Type: Relay Output
• Compatibility: Compatible with other Modicon input modules

Applications

The AS-B814-108 module is suitable for various industrial applications, including:

• Controlling motor starters
• Operating solenoids
• Activating pilot lamps
• Driving other industrial loads requiring relay outputs

Installation and Configuration

The module is initially shipped with all eight channels configured for normally open operation. Users can reconfigure any channel to normally closed by adjusting the wire jumpers on the printed circuit board. Detailed instructions for this process are provided on the module’s side label.

Maintenance

For maintenance purposes, the B814-108 module includes internal 3AG fast-acting glass body fuses in series with each output. These fuses can be accessed by removing the plate covering the option jumpers. Replacement fuse part numbers include Schneider 57-0083-000, Littelfuse 312007, and Bussman MTH7.

The Modicon AEG B814-108 relay output module offers a robust and flexible solution for managing relay-driven devices within industrial automation systems, ensuring reliable performance and adaptability to various operational needs.
