Allen-Bradley 1756HP-GPS HiProm Global Positioning System Module

Description

The Allen-Bradley 1756HP-GPS is a specialized communication module engineered by HiProm, a Rockwell Automation Encompass Partner, to provide high-precision time synchronization and location tracking within the ControlLogix platform. This single-slot module serves as a bridge between GPS satellite telemetry and the programmable automation controller (PAC) backplane, enabling microsecond-level synchronization across complex industrial control systems.

By utilizing data from the global satellite constellation, the 1756HP-GPS delivers Coordinated Universal Time (UTC) to the controller, facilitating accurate Sequence of Events (SOE) recording. This capability is essential for distributed applications where precise time-stamping of alarms and events is required to perform accurate forensic analysis of system faults across geographically dispersed infrastructure.

Features

• Precision Time Sync: Provides high-resolution UTC master time reference for ControlLogix backplane synchronization.
• Geospatial Data: Outputs real-time latitude, longitude, altitude, and velocity data directly to controller tags.
• External Antenna Interface: Equipped with a dedicated port for connection to a remote GPS antenna mast.
• ControlLogix Integration: Native integration into the chassis, occupying a single standard slot.
• Diagnostic Tracking: Monitors satellite signal strength and tracking status for reliable operation.

Applications

This module is frequently utilized in wide-area SCADA systems, utility grid management, and pipeline monitoring networks. It is particularly effective in environments requiring synchronized clock references for distributed I/O, such as leak detection systems or large-scale energy distribution networks where event timing is critical to operational integrity.

Technical Specifications

Installation Guidelines

• Slot Placement: The module can be installed in any available slot within a standard ControlLogix chassis.
• Power Safety: Ensure the chassis is powered down before inserting or removing the module to prevent electrical damage.
• Antenna Cabling: Route external antenna cables away from high-voltage power lines and high-EMI sources to maintain signal integrity.
• ESD Protection: Use standard electrostatic discharge (ESD) precautions when handling the module to protect internal circuitry.
• Grounding: Ensure the ControlLogix chassis is properly grounded in accordance with local electrical codes.

FAQ
