Information About 1766-L32AWAA

The Allen-Bradley 1766-L32AWAA is a compact Programmable Logic Controller (PLC) that is an ideal solution for micro and small automation requirements. This controller is part of the MicroLogix 1400 controller family with embedded functionalities, allowing this controller to implement digital and analog controls, both in manual or automatic mode. This controller has built-in discrete and analog I/O channels as well as variety of communication interfaces.

The 1766-L32AWAA comes with Two (2) serial communication interfaces, with primary serial interface having a 9-pin sub-D RS232C connector while the secondary serial interface having a circular 8-pin mini-DIN physical port. Both serial ports are compatible with a variety of communication protocols such as DH-485, DF1 Full-Duplex, DF1 Half-Duplex Master and Slave, DF1 Radio Modem, Modbus RTU Master and Slave, ASCII and DNP3 Slave. It is also equipped with One (1) RJ45 port supporting Ethernet I/P protocol for networked communication, supporting transmission speed of 10/100 Mbps communication speed. These ports may be used for programming and communication with Human Machine Interfaces (HMI) and Supervisory Control and Data Acquisition Systems (SCADA).

Additionally, this same communication port provides physical connection to the embedded webserver that may be accessed using standard web browsers such as Microsoft Internet Explorer, Edge, Google Chrome or Mozilla Firefox.

The 1766-L32AWAA has built-in Twenty (20) 120VAC discrete inputs, Two (2) Voltage analog inputs, Twelve (12) Relay outputs and Two (2) Voltage output channels. It also supports installation of up to Seven (7) 1762 I/O modules for expanding the embedded I/O capability of the controller.

The 1766-L32AWAA controller requires 120-240V AC input power and has battery-backed RAM. It supports 32 digital I/O points with 20 digital 120V AC inputs, 12 Relay outputs and 6 analog (12 bits) I/O points with 4 inputs and 2 outputs. It can be expanded by connecting it with as many as seven 1762 expansion I/O modules. It has dimensions of 3.5 x 7.08 x 3.43 in. and a weight of 2 lbs. For communication, it 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 Panel or DIN-Rail mounting options with an open enclosure. It is suitable for use in clean, dry industrial environments with circuits not exceeding Over Voltage Category II.

The 1766-L32AWAA controller’s Ethernet port provides DNP3 protocol support as well as web server and email capabilities. It has 2 Serial ports with DH485/DF1/Modbus RTU/DNP3/ASCII protocol support. It has up to 6 embedded 100 kHz high-speed counters (only on controllers that have DC inputs). It also has 20 KB memory for user programs and data.

Frequently Asked Questions about 1766-L32AWAA
Question: What is the main function of 1766-L32AWAA?
Date Update:11/06/2025
Answer:

The 1766-L32AWAA is a compact Programmable Logic Controller (PLC) designed for small to medium automation tasks. It provides integrated digital and analog I/O, supporting both local and networked control. This controller allows real-time monitoring and execution of control logic using ladder programming. It's ideal for applications requiring mixed signal types, such as HVAC, packaging, and OEM machinery. Its built-in web server and Ethernet port enable remote diagnostics and management.

Question: How many digital inputs does it have?
Date Update:11/06/2025
Answer:

The controller features twenty (20) embedded digital inputs rated for 120V AC. These inputs can detect ON/OFF states from field devices such as pushbuttons, limit switches, and sensors. The input signals are optically isolated for increased protection and reliability. These are grouped internally and processed via a scan cycle to update input status. This design enables fast, reliable detection for discrete control logic.

Question: How much memory does it have?
Date Update:11/06/2025
Answer:

The controller includes 20 KB of non-volatile user memory. This space is shared between ladder logic instructions and associated data, including tags, timers, and counters. It is sufficient for most small and mid-size applications. The memory is retained using a battery, preserving programs and data in case of power loss. This ensures reliable startup after downtime or maintenance.

Question: Does it have a built-in real-time clock?
Date Update:11/06/2025
Answer:

Yes, the 1766-L32AWAA comes with a built-in real-time clock (RTC). This allows the controller to execute time-based instructions, such as scheduling, logging, or time stamping. The RTC supports daylight saving adjustments and battery backup. This feature is essential for operations that depend on time triggers. It adds versatility to the control program and supports time-sensitive automation.

Question: Is the 1766-L32AWAA still in production?
Date Update:11/06/2025
Answer:

Yes, the 1766-L32AWAA is currently in production and widely supported by Rockwell Automation. It remains part of the active MicroLogix 1400 product line. This means spare parts, accessories, and firmware updates are still available. Users can rely on ongoing availability and documentation for integration and support. However, for future-proofing, newer platforms such as Micro800 are recommended.
