1764-24AWA Functional Description    

The MicroLogix 1500 Base Unit 1764-24AWA Allen-Bradley is a Bulletin 1764 base unit that forms the core of MicroLogix 1500 programmable controllers when paired with 1764-LRP/LSP processors. This modular unit features 12 embedded 120VAC inputs and 12 relay outputs (with 2 isolated relays), supporting up to 512 I/O points via expansion. Its 85-265VAC wide-range power supply (70VA consumption) ensures compatibility with diverse industrial power systems, while DIN rail mounting minimizes panel space.

Designed for small-to-medium automation, the Controller Base Units Allen-Bradley 1764-24AWA supports local expansion with eight 1769 Compact I/O modules or 16 modules in remote banks. The relay outputs handle 8A per common (1440VA break capacity), though inputs 0-11 lack adjustable filtering (20ms fixed response). Status LEDs provide real-time I/O monitoring, and the unit meets UL, CE, and Class I Div 2 safety standards.

The AB 1764-24AWA MicroLogix 1500 System includes an RS-232 port (DF1 protocol) for HMI/SCADA connectivity and supports DeviceNet/EtherNet/IP via adapters like the 1761-NET-ENI or 1769-SDN scanner. Its Channel 0 port enables flexible network integration, while the 1761-CBL-PM02 cable simplifies programming.

With 7K-12K user memory (backed by a 1747-BA battery), the Allen-Bradley 1764-24AWA In Stock delivers 1ms/K program execution speed. It accepts 1764-MM1/MM2 memory modules and an RTC clock, ensuring data retention and time-stamping. Ideal for cost-effective inventory management, this base unit maximizes I/O flexibility while maintaining compact dimensions.
