Allen-bradley 1764-28BXB lrp micrologix 1500 base unit
Allen-Bradley 1764-28BXB LRP MicroLogix 1500 Base Unit
This unit was pulled from a working system and is in very good condition.
The MicroLogix 1500 is the most expandable member of the MicroLogix family. In fact, it can handle many applications that traditionally called for larger, more expensive controllers. With its removable processor, base units with embedded I/O and power supply and expansion through 1769 Compact I/O the MicroLogix 1500 packs all of the best features of a modular system into a low-cost, small footprint.
* Application flexibility and versatility with Compact I/O means a small footprint and expansion to over 500 I/O points
* Large onboard non-volatile memory
* Real Time Clock (RTC) capabilities allow time scheduling of control
* Program portability allows user programs to be uploaded, downloaded and transported via Memory Modules
* Built in PID capabilities
* Data Access Tool (DAT) for data monitoring and adjustment
* Eight latching (pulse catch) inputs
* Four event interrupts

The enhanced MicroLogix 1500 processor (1764-LRP) provides 14K words of user-configurable memory for program and data.
You can create long-integer data files (32-bit signed integer, 2 billion) for use with math and embedded high-speed I/O instructions. You can also create floating point data files, each of which can contain up to 256 IEEE-754 floating point data elements.
The MicroLogix 1500 processes a typical 1K word user program (including bit, timer, counter, and math instructions) in approximately 1ms. Programs are created using Windows-based RSLogix 500 programming software. Programs written for other Allen-Bradley MicroLogix and SLC 500 controllers can be easily modified for use with the MicroLogix 1500 controller.
Two built-in 3/4-turn analog trim potentiometers with a digital output (range from 0 to 250) allow quick and easy adjustments of timers, counters, set points, and more. The optional Data Access Tool (catalog number 1764-DAT) adds the functions of 48 electronic push buttons, 48 electronic digital trim potentiometers, and two function keys. Trim potentiometer and Data Access Tool data is available to the user program through built-in function files.
The MicroLogix 1500 processor supports backplane messaging, which allows the processor to read or write data to other devices on DeviceNet. PCCC and CIP messaging are supported. Processor memory includes function files that store user-specified configuration data for system resources:
* Selectable Timed Interrupts
* Event Input Interrupt
* High-Speed Counters
* Pulse Train Output
* Pulse Width Modulation
* Base Hardware Information
* Trim Potentiometers
* Communication Status
* Programmable Limit Switch
