Today we are covering the Allen Bradley 1764-LRP Series C PLC. This is a MicroLogix 1500 Processor with RS-232 communication port and 14 KB words user memory. Time based or event triggered data logging.

This 1764-LRP enhanced controller provides 14 KB words of user configurable memory for program and data. An optional memory module can be installed to back up the program and data. A backup memory and real-time clock module, or the real-time clock only module can be installed separately instead of a memory.

It can also be connected to the DH-485 network using an Advanced Interface Converter (1761-NET-AIC), to an Ethernet network using an Ethernet Interface, or to a DeviceNet network through the DeviceNet Scanner module. The controller can also be connected to Modbus SCADA networks as an RTU slave.
