The Allen-Bradley 1756HP-GPS is a specialized communication module designed for the ControlLogix platform, providing high-precision time synchronization and global positioning capabilities. Developed by HiProm, a Rockwell Automation Encompass Partner, this module serves as a master time reference, utilizing GPS satellite data to maintain accurate timing across distributed control systems. It is an essential tool for applications requiring microsecond-level event logging and wide-area synchronization.

Features

• Direct integration with ControlLogix chassis for seamless backplane data communication.
• Supports high-precision UTC time synchronization for accurate Sequence of Events (SOE) recording.
• Provides real-time geographical data including latitude, longitude, altitude, and velocity.
• Interfaces with external GPS antenna hardware for reliable signal acquisition.
• Maps telemetry data directly into the controller's I/O tag database for easy access in logic programs.
• Single-slot footprint optimizes space within the ControlLogix rack.

Applications

This module is engineered for industrial environments where precise timing is critical to system integrity. Typical use cases include:

• Distributed utility and power grid monitoring.
• Pipeline leak detection systems requiring synchronized time-stamping.
• Wide-area SCADA infrastructure.
• Mobile or marine asset tracking and location-based process control.

Technical Specifications

Installation Guidelines

• Ensure the ControlLogix chassis power is removed before inserting or removing the module to prevent electrical damage.
• Install the module in any standard slot within the chassis; ensure it is fully seated and the top/bottom latches are secured.
• Use appropriate shielded cabling for the external GPS antenna connection to minimize signal interference.
• Maintain proper clearance around the module to allow for natural convection cooling.
• Handle the module using standard ESD precautions to prevent damage to sensitive internal circuitry.
