Overview
The Allen-Bradley 1760-L12DWD is a microprocessor-based Pico Controller from the 1760 series, engineered for small-scale industrial control applications. This 12VDC unit provides eight discrete digital inputs and four relay outputs in a compact, DIN rail-mountable footprint, making it an economical choice for equipment that requires simple but reliable automation logic without the overhead of larger PLC systems.
Key Features
- Embedded I/O: 8 digital inputs (12VDC) and 4 relay outputs in one integrated controller unit
- Analog Input Capability: Inputs I7 and I8 support analog signals (0–10VDC), expanding application flexibility
- Real-Time Clock: Built-in real-time clock for time-based control logic and scheduling
- High-Speed Counter: Inputs I1–I4 can function as high-speed counter inputs (≤1 kHz) for pulse-rate measurement
- Ladder Programming: Programmed via ladder diagrams using onboard keypad or PC interface with 1760-CBL-PM02 cable
- Compact Design: Small form factor (71.5 × 90 × 56.5 mm) reduces panel space and system cost

Typical Applications
The 1760-L12DWD excels in compact control scenarios including conveyor control, pump sequencing, fan speed control, lighting management, door and window control systems, and machine start/stop logic. Its low cost and minimal wiring requirements make it ideal for retrofit installations and small production equipment where a full-scale PLC is unnecessary.
Compatibility & Replacements
The 1760-L12DWD is programmed and operated using standard Allen-Bradley tools. Note: This controller was discontinued as of March 31, 2017, with the Rockwell Automation–recommended engineering replacement being the MICRO810. For legacy system maintenance, this unit remains available through authorized surplus distributors. Input I/O modules from the 1760 Pico Expansion series can be added to extend functionality. Consult the Pico Controllers User Manual (Publication 1760-UM001D-EN-P) for integration details.
