Allen Bradley 1756HP-TIME ControlLogix High-Precision Time Synchronization Module

Product Overview

The Allen Bradley 1756HP-TIME functions as a high-precision clock synchronization module within the ControlLogix platform. This specialized hardware establishes an accurate, uniform time reference across distributed programmable automation controllers, network switches, and peripheral field devices. It acts as the backbone for plant-wide Sequence-of-Events (SOE) recording, multi-axis motion coordination, and precise timestamping in power substations, oil and gas facilities, and continuous processing applications. We guarantee this unit arrives in 100% brand new, original factory condition.

Technical Specifications

Engineering Advantages

• Heavy-Duty RFI/EMI Shielding: The module meets strict IEC 61000-4 industrial immunity standards. It deflects up to 8 kV air ESD discharges and suppresses ±2 kV electrical fast transients (EFT/B) on communications lines, which prevents clock drift near high-voltage switchgear and massive motor starters.

• Chassis-Based Thermal Optimization: The hardware adapts dynamically to cabinet ventilation limitations. When engineers insert this module into a Series C ControlLogix chassis, the upgraded thermal pathways raise the maximum operating threshold to +60°C (+140°F), preventing component overheating in unconditioned environments.

• Low-Impact Backplane Draw: The module optimizes power consumption by pulling only 1.01A at 5.1V DC from the local chassis backplane. This low power signature protects your existing ControlLogix power supply capacity, leaving ample overhead for dense I/O configurations.

• Standard Single-Slot Footprint: The compact dimensions ($14.52\text{ cm} \times 3.46\text{ cm} \times 13.96\text{ cm}$) match standard ControlLogix I/O modules perfectly. It slides into any available chassis slot without disrupting wire-way routing layouts or requiring special extension brackets.

FAQs

• Does this 1756HP-TIME module arrive with its original factory packaging?

  Yes. We ship this module as a 100% brand new, original factory-sealed product. It includes all authentic manufacturer labeling, factory inserts, and box seals intact.

• How does the chassis selection affect the operating temperature of the module?

  The module utilizes the thermal properties of the hosting hardware. A Series B chassis supports a maximum ambient temperature of +50°C (+122°F), whereas a Series C chassis allows the module to run safely up to +60°C (+140°F).

• What precautions should I take regarding signal port wiring?

  You must follow Category 2 wiring guidelines for all signal and communication ports. Route these cables through dedicated conduits separated from high-voltage AC power lines to maintain optimal signal integrity and compliance with IEC standards.

• Does the module require external power connections to operate?

  No. The module draws its operating voltage ($5.1\text{V DC}$ and $1.2\text{V DC}$) directly from the ControlLogix backplane power rails when you seat it firmly into the chassis slot.
