1764-28BXB1 AB Allen-Bradley PLC MicroLogix 1500 Base Unit 1764 Series Original brand new

1764-28BXB1 AB PLC MicroLogix 1500 Base Unit 1764 Series Original brand new

System Overview
A basic MicroLogix 1500 system consists of a base unit that provides 24 or 28 built-in basic I/O, a built-in AC or DC power supply, and a processor module that slides into the base unit. You can supplement the I/O built into the base unit with up to sixteen digital and/or analog input and output 1769 Compact™ I/O modules (depending on current draw and power dissipation). Add an optional memory and/or real-time clock module or an optional Data Access Tool to enhance system capability.
