Emerson PAC8000 8750-CA-NS-01 Module

Description

Emerson PAC8000 8750-CA-NS-01

This is an 8-slot non-isolated controller rack. It is the “skeleton” for building the PAC8000 control system, determining the system’s physical size, module capacity, and basic electrical characteristics (non-isolated). When selecting, engineers need to decide whether to use a non-isolated rack or an isolated rack based on the electrical environment, signal type, and reliability requirements of the on-site application.

 

Core Features & Characteristics

1. Backplane & Structure:

   • 8 Slots: Provides 8 module slots for installing various functional modules.

   • Standard Slot Allocation:

     • Slot 1: Typically used for the Power Supply Module.

     • Slot 2: Typically used for the Controller Module.

     • Slots 3-8: Used for various I/O Modules or Communication Modules.

   • Rugged Design: Constructed with a robust metal structure suitable for industrial environments, capable of withstanding vibration, shock, and harsh temperature conditions.

2. Power Distribution:

   • The chassis backplane distributes power received from the power supply module in Slot 1 to all other modules in the remaining slots.

   • The 8750-CA-NS-01 is a Non-Isolated chassis, meaning its backplane’s I/O bus is non-isolated. This is its primary distinction from an isolated chassis.

3. Communication Bus:

   • The chassis backplane integrates an internal communication bus responsible for high-speed data exchange between the controller and all I/O modules.

4. Modularity & Flexibility:

   • Allows users to flexibly mix and configure controller, discrete/analog I/O, and communication interface modules according to specific application needs.

   • Supports hot-swapping (I/O modules can be installed or removed while the system is powered, depending on configuration and safety requirements).

Technical Specifications

• Model: 8750-CA-NS-01

• Number of Slots: 8

• Type: Non-Isolated – The I/O bus on the backplane is common, with no electrical isolation between slots.

• Compatibility: Fully compatible with all PAC8000 series controller modules, I/O modules, power supply modules, and communication modules.

• Mounting: Can be mounted on a standard DIN rail or a panel.

• Certifications: Typically carries certifications for industrial environments (e.g., ATEX, IECEx, cFM, depending on the specific ordered model).

Non-Isolated vs. Isolated Chassis

This is a critical decision point when selecting a PAC8000 chassis:

• Non-Isolated Chassis (8750-CA-NS-01):

  • Characteristic: The I/O bus on the backplane is common; all I/O modules installed in the chassis share the same electrical reference ground.

  • Advantage: Cost is typically lower than an isolated chassis.

  • Application: Suitable for general industrial applications where I/O signal types are relatively uniform, grounding is good, and there is no risk of high common-mode voltage or complex ground loops.

• Isolated Chassis:

  • Characteristic: The backplane provides independent electrical isolation for each I/O slot. The reference ground for each module is isolated from the others.

  • Advantage: Superior noise immunity, effectively preventing signal errors and equipment damage caused by ground potential differences. Enhances system reliability and safety.

  • Application: Suitable for environments with complex grounding, long cable runs, high electrical noise, or where signals from different ground reference points need to be connected.

Typical Applications

The PAC8000 system is widely used in various industrial automation and control fields. The 8750-CA-NS-01 chassis, as its foundation, is commonly found in:

• Oil & Gas production platforms and pipelines

• Refineries and chemical plants

• Power generation facilities

• Water/Wastewater treatment plants

• Pharmaceutical industry

• And other processes requiring highly reliable process control and safety monitoring systems.
