The Allen-Bradley 1766-L32AWA belongs to the MicroLogix 1400 Product family. This controller features an integrated Twenty (20) 120VAC discrete inputs and Twelve (12) Relay output channels. It is powered by with an input supply voltage of 120/240VAC.
The embedded features of this controller enable it to implement manual and automatic control of discrete processes. It is also a cost-effective solution for migrating relay based or conventional control systems to an automated system. It is especially applicable for building automation, Heating Ventilation and Air Conditioning (HVAC) systems, Water and Waste Water, food and beverage, manufacturing, conveyors and material handling systems and other applications.
The 1766-L32AWA supports expansion installation of 1762 MicroLogix I/O expansion modules where up to Seven (7) modules may be installed or up to 256 Discrete I/O may be reached. Analog expansion modules are also available for this controller to implement manual and automatic control of an analog control loop, for control of modulating devices such as Variable Frequency Drives (VFD), Modulating Valves, Dampers, Louvers and other modulating Final Control Elements.
The 1766-L32AWA supports implementation of Proportional + Integral + Derivative (PID) algorithm, for implementation of a fully automatic control system, ideal for more critical applications which require higher control accuracy and efficiency.
This controller is equipped with multiple communication ports, such as an Isolated RS232 / RS485 combo port which supports DF1 Full and Half duplex mode, DH485, DNP3, ASCII and MODBUS RTU. Another communication port which is a non-isolated RS232 ports supports the same set of protocol while Ethernet communication is an industry popular protocol capable of high-speed communication over copper-based communication cable. All these communication ports are designed for simultaneous communication to Human Machine Interfaces (HMI), Supervisory Control and Data Acquisition (SCADA), Distributed Control Systems (DCS), Protocol gateways and Converters, and messaging services.
The added support for DNP3 protocol enables this controller to communicate with electrical devices, commonly found in substation and power meter systems. Additionally, with MODBUS RTU over RS485 communication, this controller may be configured to act as the master device to allow integration of MODBUS devices particularly power meters, industrial UPS systems, compressor equipment and many other devices. ASCII protocol is used to directly integrate barcode readers, typically used in sorting and packaging applications.
The 1766-L32AWA is configured using RSLogix 500 programming software and RSLogix Micro software. These programming software packages are installed to a programming workstation to enable any user to create a program for later download to the controller. The same software is also used to implement test and commission functions as well as online editing capability. This programming software also includes the RSLinx communication software, the communication manager where drivers responsible for establishing communication are managed.
The 1766-L32AWA is also designed with an LCD and keypad assembly, used for localized monitoring of the controller, change operating mode, configure communication settings, modify registers and manipulate controller data. This controller also has an integrated Real-Time Clock, to allow scheduling of execution of user programs. This approach is used typically with pumps and compressors, to evenly distribute runtime hours.
The Allen-Bradley 1766-L32AWA is a MicroLogix 1400 Controller. This controller is designed for Power Supply input voltage of 120VAC / 240VAC with embedded Twenty (20) 120VAC discrete inputs and Twelve (12) Relay output channels. This controller has One (1) isolated RS232 / RS485 combo port, One (1) non-isolated RS232 communication port and One (1) Ethernet communication port.
F.A.Q for 1766-L32AWA
|Q: 1.What are the available communication ports for this controller? ||A: Available communication ports are One (1) isolated RS232 / RS485 combo port, One (1) non-isolated RS232 communication port and One (1) Ethernet communication port. |
|Q: 2. Does this controller come with Trim potentiometers, similar to MicroLogix 1200 controllers?||A: Yes, the trim potentiometers are accessible via the display LED. |
3. What is the size of the internal memory of this controller?||A: The 1766-L32AWA has 20KB user memory, 10 KB memory for user program and 10KB for program data. |
The 1766-L32AWA is a MicroLogix 1200 controller. In terms of functionality, this controller has the least flexible set of I/O as the integrated channels of this controller are basically standard inputs and outputs. However, it is ideal for use in automation requirements that does not have fast inputs and outputs and mix of different output type.
