Information About 1761-L32AAA

The 1761-L32AAA is an Allen-Bradley MicroLogix controller. This controller is specifically the art of the MicroLogix 1000 series, mainly used for micro and small automation requirements. It is categorized as a compact or “shoebox” controller that comes with an integrated power supply, embedded I/O channels, integrated memory, and a communication interface. Specifically, the 1761-L32AAA has an embedded power supply that internally powers the controller’s circuitry. This embedded power supply requires an external supply voltage of 120 / 240 VAC and accepts a voltage range of 85-264 VAC along with a frequency range of 47-63 Hz. The integrated I/O available to this controller includes 120 VAC / 240 VAC. It has built-in Twenty (20) 120 VAC Digital Inputs, Ten (10) TRIAC Outputs, and Two (2) Relay Outputs. It also has One (1) RS232 communication port that is configurable to communicate using the Allen-Bradley DF1 protocol. The built-in memory available to this controller is 1K Electrically Erasable Programmable Read-Only Memory (EEPROM). This memory is internally partitioned as 737 instruction words and 437 data words. It can be programmed using the Ladder programing language which is one of the recognized programming languages by the IEC 61131 standard. For installation, this controller both supports DIN-rail and Panel mounting. It measures 200 mm (7.87 in) length; 73 mm (2.87 in) in depth and 80 mm (3.15 in) in height. Recommended minimum mounting clearance is 50.8 mm (2 in.) on all sides of the controller.

The 1761-L32AAA is an Allen-Bradley PLC controller classified under the MicroLogix 1000 controller series. The 1761-L32AAA features an I/O count of 32 points. The power supply maximum inrush current for the 1761-L32AAA is rated at 30 Amps for 8 milliseconds. The module has an output type Triac controller with a power supply usage rated at 120 to 240 Volts AC. The 1761-L32AAA comes with the master control relay safety feature. The manufacturer’s recommended storage temperature range for the 1761-L32AAA is -40 degrees Celsius to 85 degrees Celsius. The operating humidity for the 1761-L32AAA is 5% to 95%, non-condensing. The unit comes with a vibration resistance of 5 Hertz to 2000 Hertz on the operating status while in the non-operating mode, the vibration resistance is 5 Hertz to 2000 Hertz. The 1761-L32AAA meets various certifications straight out of the box. These include the CUL Class 1 Division 2 Groups. The 1761-L32AAA is also UL listed and it features CE/RCM/EAC compliance. The unit comes with a terminal screw torque of 0.9 to 8.0 pounds on an inch with the electrostatic discharge rated at EN 61000-2 at 8000 Volts. The isolation rating for the part is 1500 Volts AC and it comes with a memory size and type classified as a 1K EEPROM handling approximately 737 instruction words at 437 data words. These are small in size, and they offer a high level of performance. The 1761-L32AAA fits well in smaller spaces and is powerful enough to accommodate a broad range of applications.

Frequently Asked Questions about 1761-L32AAA
Question: What is the purpose of the 1761-L32AAA controller?
Date Update:12/06/2025
Answer:

The 1761-L32AAA is a MicroLogix 1000 PLC designed for small and micro-level automation systems. It integrates power supply, digital inputs and outputs, communication, and memory in one compact unit. This controller is used for controlling discrete automation tasks in machinery and process systems. It is ideal for standalone machines that require basic control logic. Its simplicity and robustness make it suitable for industrial, commercial, or OEM applications.

Question: What is the input voltage range?
Date Update:12/06/2025
Answer:

The controller accepts a supply voltage of 120/240 VAC. It operates correctly within a range of 85 to 264 VAC at a frequency of 47 to 63 Hz. The internal power supply energizes both the logic circuit and I/O. It draws an inrush current of up to 30A for 8 milliseconds. This allows stable startup even under varying supply conditions.

Question: What communication interface is available?
Date Update:12/06/2025
Answer:

The 1761-L32AAA features a single RS232 serial port. This port communicates using the DF1 protocol and supports peer-to-peer or PC-to-PLC connections. It allows data transfer, monitoring, and programming operations. The interface is commonly used for integration with HMIs or SCADA systems. Communication settings can be adjusted via software.

Question: How is the 1761-L32AAA programmed?
Date Update:12/06/2025
Answer:

The controller is programmed using the Ladder Diagram (LD) programming language. This language conforms to IEC 61131-3 standards. Programming is done through RS232 using Allen-Bradley's DF1 protocol. Compatible software includes RSLogix 500 or Connected Components Workbench (CCW). Programs are stored in non-volatile EEPROM memory.

Question: Is the controller still manufactured?
Date Update:12/06/2025
Answer:

The 1761-L32AAA has been discontinued by Rockwell Automation. It is no longer in active production but may be available through surplus or third-party suppliers. Users should consider migrating to MicroLogix 1100 or 1400 series for support and extended features. Planning for replacement ensures long-term system reliability. Migration tools are available from Rockwell.
