Product Summary
The Allen-Bradley 1766-L32AWAA is a compact MicroLogix 1400 controller. It manages small automation tasks with 20 discrete inputs and 12 relay outputs. Engineers use this PLC for reliable, mixed-protocol industrial control.
Product Procurement & Buyer Guide
This controller provides a smart solution for micro automation systems.
You get twenty 120VAC discrete inputs for direct AC sensor wiring.
The 1766-L32AWAA also includes two voltage analog input channels.
These analog inputs accept a 0 to 10VDC signal range.
Twelve relay outputs switch loads up to 264VAC or 125VDC.
Two analog voltage outputs complete the embedded I/O set.
It requires a 120 to 240VAC external power supply.
The controller consumes 100 VA during operation.
Its operating frequency range spans 47 to 63 Hz.
You gain extensive communication flexibility with this model.
The device has one isolated RS232/RS485 combo port.
It also features one non-isolated RS232 communication port.
One Ethernet port supports 10/100 Mbps network speeds.
Serial protocols include DF1, ASCII, Modbus RTU, and DNP3.
Ethernet protocols include EtherNet/IP, DNP3, and Modbus TCP/IP.
This connectivity allows integration with SCADA and HMI systems.
It can expand with up to seven 1762 I/O modules.
Step-by-Step Installation Guide
Mount the controller on a panel or a standard DIN rail.
Its dimensions are 3.5 by 7.08 by 3.43 inches.
The device weighs only two pounds for easy handling.
Use it only in clean, dry industrial environments.
This equipment is suitable for Over Voltage Category II circuits.
First, apply the 120 to 240VAC supply to the power terminals.
Connect your 120VAC discrete inputs to the input terminals.
Wire your relay outputs to the 16 output terminals.
The relay outputs handle both AC and DC loads safely.
Connect analog voltage sensors to the two analog inputs.
Wire your field actuators to the two voltage output channels.
Next, configure the serial port for your specific protocol.
Use the isolated RS232/485 port for longer cable runs.
Connect the Ethernet port to your local area network.
Access the embedded web server using a standard browser.
Program the controller using RSLogix 500 software.
