Allen-Bradley PLC-5 / 1771 and MicroLogix
Discontinued Discontinued 2017 · Manufacturer successor: ControlLogix / CompactLogix
PLC-5 with 1771 I/O is Rockwell's 1980s-90s large-controller platform, and MicroLogix 1000, 1100 and 1500 are its small controllers. These systems remain in heavy industry and utilities. Spare processors and I/O modules are the typical urgent request.
What to check before ordering
- Processor series and revision, and memory module or battery fitted
- Series letter of 1771 I/O modules and compatibility with the existing chassis
- For MicroLogix, base unit variant (power supply, I/O count, output type)
- Whether the unit holds a program that is not backed up elsewhere
