Description
UAC317AE HIEE300725R0001 ABB High-voltage Motherboard
UAC317AE HIEE300725R0001 is a measuring interface module produced by ABB, which belongs to the signal acquisition and processing component of ABB 800xA/AC 800M integrated automation platform (DCS distributed control system).
[Product Positioning]
UAC317AE HIEE300725R0001 ABB High-voltage Motherboard
This module is a dedicated analog measurement interface in ABB DCS system, with the core function of high-precision acquisition and conversion of on-site sensor signals (such as pressure, temperature, flow rate and other process variables), and uploading the data to the controller for processing through industrial communication bus. In system configuration, it often appears as a “measurement interface” role, and multiple UAC317AE can be used in parallel to expand the number of measurement channels in the system.
[Core Function]
Multi channel analog signal acquisition: supports multiple analog inputs (AI), with a typical configuration of 8~16 channels, and can access standard industrial signals such as 4~20mA/0~10V.
Sensor Communication and Management: Supports digital communication with intelligent transmitters (such as LG1237 pressure sensors, etc.), can read sensor diagnostic information, perform remote reset and other operations.
Signal conversion: Convert on-site analog signals into digital signals for upper level controllers (such as PM865, UAC389AE, etc.) to perform PID regulation, logic control, and other processing.
Communication interface: Equipped with RS-485 serial communication (RJ-45 interface), supporting protocols such as Modbus RTU, and can exchange data with transmitters, upper computers, or other I/O modules.
Resolution: 16 bit A/D conversion accuracy, ensuring high resolution and accuracy of measurement data.
[Technical Specifications]
Power supply voltage: 24V DC (typical, powered by DCS backplane)
Working temperature: -20 ° C to+60 ° C (industrial grade wide temperature design)
Protection level: IP20 (indoor installation)
Installation method: DIN rail installation, compatible with ABB standardized I/O racks (such as TK371, TK372, etc.)
Communication interface: RS-485 (RJ-45), supports full duplex 4-wire communication, built-in 120 Ω terminal resistor (can be set through jumper)
Maximum working resistance: 750 Ω (for 4-20mA current input)
Signal isolation: Electrical isolation between the on-site side and the system side, with strong anti-interference ability
Communication and Protocol
Supports RS-485 bus communication and can directly communicate with ABB smart transmitters such as LG1237.
Supports Modbus RTU protocol and is compatible with third-party system integration.
Support remote sensor reset command (sending a reset command to global address 15 can reset all sensors).
The command response data is returned by referencing the memory, making it easy for the upper level system to read.
Typical application scenarios
Process variable acquisition in power plant DCS system (pressure, temperature, flow rate, liquid level)
Automated production line monitoring in industries such as petrochemicals, metallurgy, and water treatment
Measurement signal access in ABB excitation system (UNITROL 5000/6000)
Used in conjunction with Bently 3500 monitoring system (this model has clear associated records in the Bently 3500 spare parts list)
Any industrial process control scenario that requires high-precision multi-channel analog data acquisition
[Associated Model]
Same series: UAC317AE01, UAC317AE02 (different variants)
Similar function: UAC318AE HIEE300744R0001 (another measurement interface)
Supporting use: PM865, SM810/SM811 (power/diagnostic module), CI801, CI840/CI840A (communication module), TB820/TB840 (terminal board)
Engineering tool: ABB Automation Builder (800xA system programming and configuration)
[Precautions for use]
This module is a specialized component for DCS system measurement. When replacing it, it must be confirmed that the model is completely consistent (HIEE300725R0001) and cannot be mixed with ordinary I/O modules or other platform controllers.
When communicating with RS-485, attention should be paid to the terminal resistance setting: If the module is at the beginning or end of the RS-485 network, a 120 Ω terminal resistance must be enabled (set through jumpers or shorts), otherwise it may cause communication errors.
When it comes to safety function applications, debugging needs to be carried out by engineers with functional safety qualifications.
Due to the predominance of inventory and disassembled parts in the market for this model, it is recommended to prioritize confirming the reliability of spare parts sources and verifying system compatibility (800xA/AC 800M/AC 800M HI platform) during procurement.
