ABB AI845

Details

Operating Parameters

Input Signal Types:

It supports analog signal inputs such as 0-20 mA, 4-20 mA, 0-5 V or 1-5 V DC, in single-ended and single-polar mode.

Number of Channels:

It has 8 channels.

Resolution: 

With a 12-bit resolution, it can convert analog signals into digital signals relatively accurately.

Input Resistance: 

For voltage input, the input resistance is greater than 10 MΩ; for current input, the input resistance is 250 ohms. It can withstand an overvoltage or undervoltage of at least 11 V DC.

Product Dimensions: 

The net depth/length of the product is 102 mm, the net height is 119 mm, and the net width is 45 mm. The net weight of the product is 0.2 kg.

Product Features

Multi-mode Applicability:

ABB AI845 can operate in either single mode or redundant mode, applicable to different system reliability requirement scenarios. Firstly, it can ensure the stable operation of critical applications over a long period of time and minimize the downtime caused by module failures of the entire system. Secondly, it supports multiple Module Terminal Units (MTUs). When using MTU TU844 or TU845, each channel can flexibly choose voltage or current input; when using other MTUs, all channels are uniformly set to voltage or current input, which is convenient for users to configure according to actual needs.

Enclosure: 

The enclosure has a height of 119 mm, a length of 102 mm, and a width of 45 mm. There are 8 channels, and each channel has a 12-bit resolution, enabling relatively accurate signal conversion and integration. The net weight is 0.2 kg.

Isolation: 

There is a group of 8 channels isolated from the ground. This isolation design effectively reduces the interference between signals, improves the accuracy and stability of the signals, and also protects the module and the entire system from external interference.

Diagnostic Function: 

The advanced on-board diagnostic function can monitor the running status of the module in real time, detect and report possible failures promptly, avoid subsequent failures within the system, remind users to carry out maintenance, and ultimately reduce maintenance costs and the possibility of downtime.

Communication Ability: 

ABB AI845 supports HART pass-through communication, enabling it to communicate with HART-compatible transmitters, thereby realizing remote configuration and monitoring of the transmitters and making the system management more intelligent and efficient.

Power Supply: 

Each channel has its own current-limiting transmitter power supply, which can control the power supply to the transmitters and other equipment. In addition, the power of the transmitter is current-limited and monitored to ensure the safety and stability of the power supply and avoid damage to the equipment caused by overcurrent or other problems.

Application Fields

Power Industry: 

It can be used in power plants, substations and other places to collect and monitor analog quantity signals such as voltage and current in the power system, conduct real-time monitoring and protection of the operating status of power equipment, and ensure the safe and stable operation of the power system.

Energy Field: 

In the oil, natural gas and other energy industries, ABB AI845 is used to monitor and control parameters such as pressure and flow in the production process and optimize the process to improve the efficiency of energy exploitation and utilization.

Chemical Industry: 

For the automatic control systems of the chemical production process, it helps to accurately measure and control analog quantity signals such as temperature, liquid level and composition, aiming to ensure the safety, stability and high efficiency of chemical production.

Pharmaceutical Industry: 

ABB AI845 is used to control the operating parameters of equipment in the pharmaceutical production process, such as composition and drug quality, to maintain the quality and safety of drug production.
