Description

PVD164A2059 (Order Number 3BHE014340R2059) is a process variable diagnostic module produced by ABB, mainly used for signal acquisition, diagnostics, and processing in industrial automation systems. The following is all the detailed information about it:

Core Functions

1. High-Precision Signal Acquisition: Supports the acquisition of analog signals (such as 4-20mA, 0-10V, and other industrial standard signals). Can connect to sensors for temperature, pressure, flow, etc., to achieve real-time monitoring of on-site process variables.

2. Fault Diagnosis and Alarm: Features signal anomaly diagnosis capabilities, able to detect faults such as disconnection, short circuit, and over-range, and trigger alarms through the system to reduce equipment downtime risk.

3. Signal Isolation and Interference Resistance: Equipped with built-in electrical isolation design to effectively suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in industrial environments, ensuring stable signal transmission.

4. Data Preprocessing: Can perform preprocessing on collected raw signals, such as linearization and filtering, and output standardized data to upper-level controllers, reducing system computation load.

5. Redundancy Compatibility: Supports adaptation to ABB system redundancy architectures and, in some scenarios, can achieve module-level redundancy to enhance overall system reliability.

Physical and Installation Parameters

1. Dimensions: Approximately 150mm (L) × 110mm (W) × 25mm (H) (subject to the actual product, compatible with standard DIN rail or ABB system rack installation)

2. Installation Method: DIN rail mounting (compliant with EN 50022 standard rails) or fixed to the system rack with screws

3. Weight: Approximately 300g (single module weight, excluding connecting cables)

Application Areas

1. Process Industry: DCS systems in industries such as petrochemicals, chemicals, and metallurgy, used to collect key process parameters like reactor pressure, pipeline flow, and medium temperature.

2. Energy Industry: Auxiliary systems in thermal power plants and nuclear power plants (e.g., feedwater systems, desulfurization systems), monitoring pump and valve status, medium levels, and other variables.

3. Manufacturing Industry: Production lines in paper, cement, and food processing, used for real-time monitoring of equipment operating parameters and anomaly diagnosis to ensure production continuity.

4. Infrastructure: Water treatment plants and urban heating systems, collecting signals such as water quality indicators (e.g., pH value, turbidity) and pipeline pressure to support remote control.

Product Features

1. High Reliability: Uses industrial-grade components and has passed environmental tests such as high temperature and vibration, meeting the long-term stable operation requirements of industrial sites (MTBF – Mean Time Between Failures ≥ 100,000 hours).

2. Ease of Maintenance: The module supports hot-swapping (in certain system adaptation scenarios), allowing replacement without power shutdown, thereby reducing system downtime; the front panel features status indicator lights (power, communication, fault) for quick troubleshooting.

3. System Compatibility: Can be seamlessly integrated into DCS systems such as ABB Advant OCS and AC 800M, and can also adapt to third-party control systems (such as Siemens and Rockwell systems) through protocol conversion modules.
