The Allen-Bradley 1766-L32BWAA is a MicroLogix 1400 Programmable Logic Controller. It comes with the EtherNet/IP network, online editing capabilities, and a built-in LCD with enhanced network capabilities. There is also a backlight on the LCD to set the network configuration and view the controller and I/O status. The 1766-L32BWAA controller requires 120 to 240 Volts AC input power and it has battery-backed RAM. It supports 32 digital I/O points that consist of 12 digital fast 24 Volts DC inputs, 8 digital normal 24 Volts DC inputs, 12 relay outputs, and 6 analog (12 bits) I/O points with 4 inputs, 2 outputs. It can be expanded with as many as seven 1762 expansion I/O modules. It has dimensions of 3.5 x 7.08 x 3.43 inches and it weighs 2 pounds.

For communication, the 1766-L32BWAA has an isolated RS-232/485 port, an Ethernet port, and a non-isolated RS-232 port. It also has an embedded real-time clock to provide a reference for applications that need time-based control. For installation, it has the panel or DIN-rail mounting options with an open enclosure. It is suitable for use in a clean and dry industrial environment with circuits not exceeding Over-Voltage Category II.

The 1766-L32BWAA controller comes with an Ethernet port that provides DNP3 protocol support as well as a web server and email capabilities. It has 2 Serial ports with DH485/DF1/Modbus RTU/DNP3/ASCII protocol support, up to 6 embedded 100 kHz high-speed counters, and a 20 KB memory for user programs and data.

The 1766-L32BWAA is MicroLogix 1400 controller that is manufactured by Allen-Bradley. This controller features a user program memory of 10KB and data space of 10KB. It has a variety of input and output channels such as Twenty (20) digital 120V AC inputs, Four (4) 0-10VDC analog inputs, Twelve (12) Relay outputs and Two (2) 0-10VDC analog outputs. The analog input has a resolution of 12-bit and converted to a 12-Bit signed integer value. The analog output has typical parameters with an output resolution of 12 bit unsigned integer.



It is provided with Two (2) Serial ports such as One (1) Combo isolated channel compatible for RS232 / 485 communication, One (1) non-isolated RS232 channel and One (1) Ethernet communication port. Serial protocols support communication protocols such as DF1 Full Duplex, DF1 Half Duplex Master/Slave, DF1 Radio Modem, DH-485, Modbus RTU Master/Slave, ASCII, DNP 3 Slave. Ethernet port supports Ethernet based protocols such as EtherNet/IP messaging, DNP3 over IP and Modbus TCP/IP.

Aside from the embedded analog inputs channels, this controller also features integrates Trim Potentiometers that may be used to simulate internal registers or incorporate to a user program for manual analog entry or test parameter.
