The Allen‑Bradley 1766-L32BWAA belongs to the MicroLogix 1400 controller series for small to medium automation systems.
It integrates a built-in LCD with backlight to view status and configure network settings directly on the unit.
This controller supports online program editing and offers flexible communication for industrial control applications.
It runs on 100–240V AC power and uses battery-backed RAM to maintain programs and data during power interruptions.
The 1766-L32BWAA provides a total of 38 I/O points, including discrete, relay, and analog signal channels.
It features three communication ports: Ethernet, RS232, and an isolated RS232/RS485 combo port.
A built-in real-time clock supports time-based control, scheduling, and event timestamping functions.
The controller can expand with up to seven 1762 expansion modules for increased I/O capacity.
It supports both DIN-rail and panel mounting for easy installation in control cabinets.
The 1766-L32BWAA includes 20 digital DC inputs: 12 fast 24V DC and 8 standard 24V DC channels.
It provides 12 relay outputs for switching common industrial loads and field devices.
Four analog inputs support 0…10V DC signals with 12-bit resolution for accurate measurement.
Two single-ended analog outputs deliver 0…10V DC control with 12-bit unsigned resolution.
Total I/O points reach 38, combining discrete and analog capabilities in one compact unit.
Integrated trim potentiometers allow manual analog simulation for testing and setup.
This controller offers 10KB program memory and 10KB data memory, for a total of 20KB user memory.
It supports up to six 100 kHz high-speed counters for fast pulse and position monitoring tasks.
Analog inputs convert to 12-bit signed integers for precise processing in user applications.
Analog outputs use 12-bit unsigned values for smooth and stable control of field equipment.
Battery-backed RAM ensures program and retain data are preserved during power loss.
The 1766-L32BWAA has one Ethernet port supporting EtherNet/IP, Modbus TCP/IP, and DNP3.
It includes one isolated combo port for RS232 and RS485 serial communication.
An additional non-isolated RS232 port is available for programming or serial device connection.
Supported serial protocols include DF1, DH485, Modbus RTU, ASCII, and DNP3 Slave.
The Ethernet port also provides a built-in web server and email notification functions.
Operating voltage range is 100 to 240V AC at 47–63 Hz with power consumption of 120 VA.
Inrush current is 25A for 8 ms at 120V AC and 40A for 4 ms at 240V AC.
The unit is rated for Over-Voltage Category II installations in clean, dry environments.
It uses an open chassis design suitable for standard industrial control panels.
Dimensions are 3.5 x 7.08 x 3.43 inches for compact mounting in limited spaces.
Shipping weight is 2.00 lbs, making the controller lightweight and easy to handle.
Mounting options include standard DIN rail and direct panel installation.
A backlit LCD displays controller status, I/O state, and network configuration.
Mount the 1766-L32BWAA on a DIN rail or secure it to a panel with mounting screws.
Connect 100–240V AC power to the designated power terminals with correct wiring.
Attach 24V DC sensors and input devices to the 20 digital input channels.
Wire field loads to the 12 relay output terminals using appropriate wire gauge.
Connect analog sensors (0–10V DC) to the four analog input channels.
Link analog output devices to the two 0–10V DC analog output terminals.
Connect serial equipment to the RS232 or RS232/RS485 port for DF1 or Modbus RTU.
Plug an Ethernet cable into the Ethernet port for network access and programming.
Apply power and use the front LCD to check controller and I/O status.
Set IP address and communication parameters via the LCD or programming software.
