Information About 1764-28BXB
The 1764-28BXB is part of the Allen-Bradley Bulletin 1764 MicroLogix 1500 family, designed as a base controller unit that combines power, I/O, and communication functions. It operates on a 20.4–30V DC power supply, consuming up to 30W. This base unit includes 16 inputs, divided into 8 standard 24V DC sink/source inputs and 8 high-speed 20 kHz inputs, making it suitable for precise motion and counting applications. The outputs include 6 relay channels rated for 24–125V DC or 120–240V AC, along with 4 standard DC transistor outputs and 2 high-speed 20 kHz transistor outputs. The FET transistor outputs are unique to this base model, supporting applications that require fast switching. The 1764-28BXB also integrates an RS-232 communication port for programming, device networking, and peer-to-peer connections, while supporting expansion up to 512 I/O points with additional modules. Its compact design allows for efficient integration in automation systems while maintaining flexibility for scalable applications.
Key Features:
- Integrated I/O: 16 DC inputs (8 standard, 8 high-speed up to 20 kHz) for versatile sensing and counting applications.
- Relay Outputs: Six relay outputs rated for both AC (120–240V) and DC (24–125V) loads, providing switching flexibility.
- Transistor Outputs: Four standard 24V DC outputs and two fast 20 kHz DC transistor outputs for high-speed applications.
- Power Supply: Operates from 20.4–30V DC with a power consumption of up to 30W and maximum load power of 16W.
- High-Speed I/O: Eight 20 kHz inputs and two 20 kHz outputs for motion control and fast counter functions.
- Communication: Integrated RS-232 communication port supporting DF1 protocol for programming and device communication.
- Expansion Capability: Supports up to 512 I/O points with expansion modules, enhancing system scalability.
- Construction: Compact and robust design with relay and transistor output mix, suited for flexible automation tasks.
The 1764-28BXB delivers the scalability, speed, and flexibility required for reliable performance in MicroLogix 1500 automation systems.
