The Allen-Bradley MicroLogix 1200 is a compact, fixed I/O programmable logic controller (PLC) from the MicroLogix 1000 family. It was designed for simple, stand-alone automation applications requiring a limited number of inputs and outputs. The “1762-L24BWA” model is a 24V DC input / 24V DC output (sourcing) unit with a built-in power supply.
It is a mature product, and while still supported by Rockwell Automation, it has been largely superseded by newer platforms like the Micro800 series.
Detailed Model Number Breakdown: 1762-L24BWA Ser C Rev I
-
1762:Â The family designation for MicroLogix 1200 controllers and their associated I/O expansion modules.
-
L: Indicates it is a Logic Controller (the CPU).
-
24:Â Specifies the total number of built-in I/O points.
-
20 Discrete Inputs (24V DC)
-
4 Discrete Outputs (24V DC Sourcing)
-
-
B: Indicates the controller has a Communication Port (RS-232 DF1 protocol) for programming and HMI connectivity.
-
W: Signifies the unit has a real-time clock (RTC). This allows the controller to time-stamp events and run programs based on the time of day.
-
A: Denotes the Input/Output type and power supply.
-
A in this context means: 24V DC Inputs and 24V DC Sourcing Outputs, with a 85-265V AC or 85-305V DC built-in power supply.
-
-
Ser C: The Series identifier. Later series (like C) often included minor hardware improvements and bug fixes over earlier series (A, B).
-
Rev I: The Revision level. This indicates a specific engineering revision of the hardware.
