About 1764-LRP/B

The 1764-LRP Series B processor is an improved MicroLogix 1500 processor manufactured by Allen Bradley/Rockwell Automation as part of the MicroLogix 1500 product line. This processor is designed to provide memory solutions for various industrial applications. It also offers 14 KB of operator-configurable memory for program data and information. Also, the processor features a program execution time of about 1 millisecond per 1K-word program, counting bit, timer, math, or counter instructions. The Allen-Bradley 1764-LRP processor offers trim potentiometers, a communication toggle push button, a run/program/remote mode switch, and logic processing for any controller system. The processor also acts as the interface for DAT, real-time clock, and memory modules. This processor utilizes a controller assembly which supports up to 8 input and output modules with an extra I/O bank. This processor features Version 4.0 of the RSLogix 500 software for programming purposes.

The Allen-Bradley 1764-LRP Series B processor is an enhanced version of a standard processor, and no isolator is needed to connect the MicroLogix controller system to a computer through the 1764-LRP Series B processor. This processor requires a battery backup as soon as the battery indicator light automatically turns on because the original battery cannot last for more than 7 days. The 1764-LRP Series B processor has Modbus, DH-485, DF1, and ASCII communication ports that are independently-configurable for any supported communication protocol. The processor is intended for use with the Series B or higher devices. The RS-232 port is utilized for the SCADA/RTU communication networks.
