ACQUISITIONLOGI AL81G Input output module

Input/output module 1. Input/output module
Function: Designed to convert analog signals from sensors or other sources into digital signals that can be processed by PLC systems.
characteristic:
It has 8 input channels, each of which can be configured as a different type of analog signal, such as voltage or current.
The supported signal types include 0-10V, 0-20mA, 4-20mA, and thermocouple signals.
Equipped with a high-resolution ADC (Analog to Digital Converter), it can process signals up to 16 bits.
Equipped with LED indicator lights, it can display the status of each input channel for easy monitoring of module performance.
Easy to install and use, it can be easily installed into the corresponding PLC system using the built-in installation clip.
2. Radio communication module
Function: Provides deterministic control and PC connectivity, supports complex mathematical algorithms and string or array data processing.
characteristic:
Suitable for backplane communication with DL205 CPU slots and DL205 I/O 40MHz or 100MHz CPU models.
Built in Ethernet port and RS232 serial port, supporting MODBUS wireless communication system and MODBUS trade agreement (only supported).
Equipped with advanced software development tools for easy control, data management, communication, and integration with business systems.
Can be used by VB and C++programmers to develop their own control code.
3. Digital input module
Function: Provides multiple input channels for receiving external digital signals and monitoring the status of switches, sensors, or other digital input devices.
characteristic:
Supports different types of digital input signals, such as discrete signals (such as switch states), pulse signals (such as encoder outputs), or high-speed counter signals.
It may include signal processing functions such as filtering, debounce, and signal amplification.
Provide logical functions such as edge detection (triggered by rising or falling edges) and counter functionality.
It has standard interfaces such as digital input/output (I/O) interfaces, Ethernet interfaces, serial interfaces (such as RS-232 or RS-485), etc., making it easy to connect to other devices or systems.

The less people know about our company and technology, the more successful we are, “said Ke Ruisi, former President of ABB China and now Executive Vice President of ABB Group, with a smile when talking to reporters about ABB’s World Expo trip.

Although it did not win the title of Global Partner at the Shanghai World Expo like its main competitor Siemens, this electrical giant still won 53 projects at the Shanghai World Expo through open bidding.

For example, the central stage of the World Expo Cultural Center uses ABB frequency converters to precisely control the operation of various motors; The Expo’s rail transit line extensively uses ABB’s complete set of transformers. In addition, the construction of the World Expo supporting facilities and China’s only 500 kV underground substation – Jing’an Center Underground Substation – also uses ABB 550 kV gas insulated switches.

For example, if your home appliances are functioning properly, it means that behind these products, our equipment is very stable, “explained Ke Rui.” Once a problem occurs, users will trace back to us and find us. “As a company that provides technical services to end product manufacturers, we do not directly contact end consumers.

Of course, the World Expo Park is just a microcosm of this company’s fierce competition in China. Against the backdrop of the 2009 financial crisis, ABB increased its investment in China, reaching a proportion of 19%. These investments are mainly used to establish new joint ventures in the world’s largest market.

Railways, smart grids, and new energy are all key development areas that ABB hopes to focus on in China in the future.

Taking advantage of the rapid development of China’s wind energy industry, ABB’s orders in China increased by 125% last year. As the world’s largest supplier of wind turbine electrical components, ABB holds 70% of the equipment products, including transformers, in wind power plants.

The domestic railway is also a huge market that ABB is looking forward to. By 2020, the country plans to build 160000 kilometers of railways, 60% of which will be electrified. ABB has already received good returns in China, with orders increasing by 380% last year compared to 2008.
