Series & Revisions

Series B in stock; other series on request.

Series notes: A later series runs the existing program after the processor type is changed in RSLogix 500. An earlier series may not if the program uses features from a newer OS/FRN.

Intended Use

Built for small standalone machine and remote-site control applications. MicroLogix 1400 controllers run pump stations, lift stations, small packaging and OEM machines and remote telemetry panels, with built-in Ethernet, serial ports, a front LCD and data logging in a brick-style unit expandable with 1762 I/O.

Common 1766-L32BXB failures

Failure patterns we regularly see on MicroLogix 1400 controller hardware like the 1766-L32BXB:

Program lost after a power event: memory module (1766-MM1) or internal backup failed
Power supply section failure leaving a dead unit
Embedded Ethernet port dead or dropping connections
LCD blank, garbled or unresponsive keypad
Output relays welded or burned on high-cycle machines (relay-output models)

Repair or replace?

ReplaceReplace the 1766-L32BXB if it will not boot, shows a solid red fault light, or has lost its program. Another MicroLogix 1400 controller takes the same program: download it, match the firmware, and the line is running again. Order the exact 1766-L32BXB. The catalog number sets the 32-point density and 24V DC rating, and a different suffix changes one of them. The 1766-L32BXB is on our shelf now and ships the same day for orders placed before 5:00 PM Central.

RepairRepair the 1766-L32BXB when the fault is in the power section, a port or the status display rather than the processor core, or when the controller carries a firmware revision or validated project you cannot easily re-flash onto a different unit. The two 1766-L32BXB symptoms we see most often are “Embedded Ethernet port dead or dropping connections” and “LCD blank, garbled or unresponsive keypad”. If a replacement is already installed, repairing the failed 1766-L32BXB gives you a tested spare on the shelf for the next failure. Each 1766-L32BXB we repair goes back function-tested with a 1-year warranty.
