Allen Bradley Compact-IO based on the Bulletin 1769 Compact I/O is the chassis-based modules built for local and distributed I/O for Allen Bradley’s CompactLogix, Compact GuardLogix, or MicroLogix 1500 controller. It features a rackless design to reduce costs of installation and to save space to the parts inventory. The module has a built-in removable block that provides connections to actuators and I/O sensors. There are various types of 1769 Compact modules starting from digital, analog, as well as specialty I/O modules. Each of modules comes with their specifications and specialties. Among of that, in fact there are several main features offered by Bulletin 1769 Allen Bradley Compact-IO.
Features of Bulletin 1769 Allen Bradley Compact-IO Modules
As the ranges of 1769 Allen Bradley Compact-IO Modules as part of the chassis-based modules, the most prominent beneficial feature is due to their flexibility. The 1769 Allen Bradley Compact-IO Modules are compatible with DIN rail or panel mounting options. All units include individual point diagnostics with status indicators for easier troubleshooting. The software keying provided to prevent incorrect positioning of module. Users can connect up to three banks of Compact I/O to a controller as they are installed communication adapter module and power supply.
The Several Types of 1769 Allen Bradley Compact-IO Chassis-Based Modules
The 1769 Allen Bradley Compact-IO Modules has several types to support users need as below:
1769 Compact Digital I/O Modules
This type of Allen Bradley Compact-IO Modules offers a variety of AC and DC voltages. The type also includes 8-32 points per module, contact output models, and high-speed input modules. As for further benefit the type, also offer input filtering mechanism and optical isolation feature.
1769-AENTR I/O Modules
The Aentri Allen Bradley Compact-IO Modules support for single network system to EtherNet/IP TCP-CIP connection 96. There are available dual linear topologies as good as DLR with the distribution of input and output via EtherNet/IP. The modules also offer direct connection. Other benefits are including control migration with the existing 1769 I/O and I/O packet rate of 10,000 pps.
1769 Compact Analog I/O Modules
The 1769 Compact Analog I/O Modules has high accuracy ratings. The features include over-range and under-range detection/indication, on-board scaling, and ability make direct output device operation in the abnormal condition. Auto calibration of inputs also included. The modules are also aimed for individual configurable channels.
The data on each on-board module can be configured as Engineering Units in volts or milliamps, scaled-for PID, percent of range and raw or proportional data for optimum resolution.
1769 Compact Specialty I/O Modules
The 1769 Compact Specialty I/O Modules are available for address reverse, ASCII, Boolean control, and high speed counter modules. The modules offers direct 1769 platform connection to various drivers (including PowerFlex) and various devices using Compact I/O to DPI/SCANport and Compact I/O to DSI/Modbus modules.
Conclusion
Allen-Bradley Compact I/O modules are available in various types. In addition to the compact design of each unit for super versatile and easy installation, they are also features great benefits and features on each unit. Users can select among four available choices depending on their requirements. In instance, they should pick for the Compact I/O Analog if they want range of benefits to select power source, on-board scaling, individually configurable channels and auto calibration if inputs.
