It offers 1K words of user memory (approximately 737 instruction words and 437 data words) stored in non-volatile EEPROM, ensuring data retention without a backup battery. With 20 AC digital inputs and 12 relay outputs, it supports both 24–125V DC and 0–240V AC output voltage ranges. Communication is handled via an integrated RS-232 port using the DF1 protocol, with optional connectivity through DeviceNet Interface (DNI) modules for expanded networking. The unit measures 7.87 x 2.87 x 3.15 inches, supports both horizontal and vertical mounting, and requires clearance for airflow. Despite being discontinued, the 1761-L32AWA remains widely used in legacy automation systems. Key Features: I/O Capacity: 32 I/O points with 20 AC digital inputs and 12 relay outputs. Memory: 1K EEPROM memory (737 instruction words, 437 data words) for program storage. Input and Output Ratings: Inputs rated for 120V AC; outputs rated for 24–125V DC or 0–240V AC. Communication: Integrated RS-232 port with DF1 protocol, expandable with DeviceNet Interface for networking. Power Supply: Operates at 120/240V AC with 19 VA (120V) or 25 VA (240V) consumption. Safety Features: Includes a master control relay; suitable for Class 1, Division 2 hazardous locations with enclosure. Mechanical Design: Compact dimensions (7.87 x 2.87 x 3.15 in.), supporting horizontal or vertical mounting with airflow clearance. Environmental: Operating temperature range of 0–40 °C, shock tested to 9 g peak acceleration for 11 ms on three axes. The 1761-L32AWA delivers dependable performance and basic automation functionality, making it a durable choice for legacy MicroLogix-based systems.
