Description

Allen-Bradley 1769-BOOLEAN CompactLogix Boolean Control Module

Configured for Boolean signal execution in CompactLogix control systems, the Allen-Bradley 1769-BOOLEAN (1769-BOOLEAN Boolean Control Module) provides direct physical and electrical control of sink inputs and source outputs. The module operates at 24 VDC and uses I/O memory mapping for application-specific configuration.

EtherNet/IP and CompactLogix I/O Integration

The 1769-BOOLEAN module operates within the CompactLogix platform through the local I/O architecture. Therefore, the controller exchanges Boolean data through the mapped I/O memory structure. The module supports configurable input and output behavior, which allows engineers to define signal handling according to machine control requirements.

In addition, the CompactLogix backplane communication system transfers control data between the controller and the Boolean module. The module supports I/O density scaling within the CompactLogix family, while firmware compatibility depends on the installed controller and system revision.

Frequently Asked Questions

Q: What type of signals does the 1769-BOOLEAN module process?
A: The module processes Boolean signals through sink-type inputs and source-type outputs with a 24 VDC operating voltage.

Q: Can the terminal block of the 1769-BOOLEAN module be replaced?
A: Yes. The terminal block and access door can be replaced using compatible CompactLogix accessory components.

Q: Does the 1769-BOOLEAN module require a separate communication interface?
A: No. The module communicates through the CompactLogix local I/O backplane connection.

Field Installation Guidelines

Install the 1769-BOOLEAN module on a compatible CompactLogix system rack according to the controller and I/O installation manual.

Maintain proper separation between control wiring and high-voltage power conductors to reduce electrical interference. Connect field wiring with correct polarity for sink inputs and source outputs.

Use suitable grounding practices for the control cabinet and verify shield termination methods when signal cables require noise protection. Confirm backplane power loading before adding additional modules to the CompactLogix system.

Before commissioning, check I/O mapping configuration, controller recognition, and field signal response through the programming environment.
