X20AI8221 - Analog input module - B&R
This B&R analog input module is reference X20AI8221. It belongs to the X20 range.
X20 analog input module, 8 inputs, ±10 V, 13-bit converter resolution
This B&R input module is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
With its well thought-out details and a sophisticated ergonomic design, the X20 system is more than a remote I/O system – it is a complete control solution. The X20 system family combines the components that are needed according to the requirements and the application.
Each module consists of 3 subcomponents – the terminal block, electronics module and bus module. This results in a system that combines many advantages:
• Pre-wiring without modules
• Hot-pluggable electronics
• Bus connector slots available for options
X20 modules consist of three submodules to provide maximum ease of use throughout their entire life cycle. This division into bus module, electronics module and terminal block has several advantages.
• Preconfigured for different machine types
X20 bus modules are the basic platform for many machine variants. The electronics modules used determine the machine's degree of expansion. The software automatically detects this degree of expansion and makes the necessary functions available.
• Industrial control cabinet construction
X20 system terminal blocks are separate from the electronics module and make it possible to pre-wire the entire control cabinet. This is especially ideal for series-produced machines.
• Easy maintenance
X20 modules can be easily exchanged to simplify troubleshooting. The electronic modules can be exchanged without interrupting operation. The wiring remains exactly the same thanks to the separate terminal blocks. Being able to exchange the automation components quickly reduces downtime.
The X20 system makes it possible to combine the exact components necessary depending on the user's demands and individual application requirements. This allows machine options to be implemented easily and flexibly. Bus modules provide the base, and are more or less a rack replacement. Depending on the option, the necessary electronics modules are then inserted in the predefined slots.
Addresses are assigned implicitly via the slot. Software that has been developed once is valid for all versions and does not need to be changed. This is even possible for later machine expansion. The I/O modules are simply inserted in the defined bus modules, and assigned to the corresponding potential groups and E-stop groups.
To prevent unwanted expansion, each module can be identified and then enabled using the application software.
The CPUs in the X20 system series cover a wide range of requirements. Areas of use include simple applications where cycle times in the millisecond range are sufficient to applications that place the highest demands on performance. Even cycle times of 100 μs can be used effectively.
In terms of design, the CPUs correspond to the X20 system. X20 I/O modules are connected directly to the CPU.
Attached seamlessly to the CPU, they allow the entire space-saving system to fit inside the control cabinet. The supply for the CPU, X2X Link power supply and I/O modules is part of the CPU. No additional power supply modules are required.
Bus controllers consist of a base module, power supply module for providing power to the entire system and the fieldbus interface. This makes the bus controller an extremely flexible fieldbus interface.
Unlike a CPU with an integrated fieldbus connection, the bus controller does not need to be programmed in order to transfer or receive I/O data on the fieldbus. It works simply by configuring it on the fieldbus master.
Expandable bus controllers
On expandable bus controllers, up to 2 interface or hub expansion modules can be connected depending on the bus module being used.
Coated modules are X20 modules with a protective coating for the electronics component. This coating protects X20c modules from condensation and corrosive gases.
The modules' electronics are fully compatible with the corresponding X20 modules.
