Emerson PAC8000 8522-EB-NV-01 Input safety barrier module

Description

Emerson PAC8000 8522-EB-NV-01

This is an 8-channel thermocouple input safety barrier module designed for the PAC8000 process automation control system.

Key Features & Functions

1. Signal Type:

   • Input: Accepts signals from eight thermocouples. It supports various common thermocouple types (e.g., J, K, T, E, R, S, B, N, C), which are typically configured via the system software.

   • Output: Transmits the converted digital signal to the PAC8000 controller via the backplane bus.

2. Intrinsic Safety (IS):

   • This is its core value as a “safety barrier.” The module provides an intrinsic safety barrier for each thermocouple line connected to the hazardous area.

   • It limits the energy (voltage and current) supplied to the hazardous area, preventing electrical sparks from igniting flammable gases or dust, thus ensuring the safe operation of the entire system. It typically holds safety certifications such as FM, ATEX, and IECEx.

3. Channel Count:

   • 8 channels. This allows one module to process eight independent thermocouple signals simultaneously, offering high density that helps save cabinet space and cost.

4. High Accuracy & Reliability:

   • Features high-precision analog-to-digital converters and provides Cold Junction Compensation (CJC) to ensure accurate temperature measurement.

   • Offers strong immunity to electromagnetic interference, making it suitable for harsh industrial environments.

5. Diagnostic Capabilities:

   • The module provides comprehensive diagnostics, capable of detecting issues such as wire break (open circuit), signal out-of-range, module hardware fault, and power supply abnormality. It reports these issues to the control system, enabling quick troubleshooting and maintenance.

6. Integration & Configuration:

   • As part of the PAC8000 family, it communicates with the controller and other I/O modules via a standard backplane.

   • It is configured using Emerson’s PROFICIY Control System (PCS) or related configuration tools, where parameters like thermocouple type, engineering units, and alarm limits are easily set.

7. Nomenclature Breakdown:

   • 85: Series number for PAC8000 I/O modules.

   • 22: Specific model identifier for an 8-channel thermocouple input.

   • EB: Typically stands for “European Board” or a specific hardware version identifier.

   • NV: This combination is critical. It stands for Non-Isolated Version. This means the 8 channels are not electrically isolated from each other; they typically share a common reference. This is acceptable in many applications, but requires special attention if high common-mode voltages are present.

   • 01: Hardware revision number.
