3283C Rev W
Product Name **3283C Rev W** Allen-Bradley 16-Channel Analog Input Module (Legacy PLC/SLC Compatibility)
Model Interpretation:
- “3283C”: Allen-Bradley’s legacy product code for high-density analog input modules, part of the 3200 series I/O family designed for PLC-5 and SLC 500 platforms.
- “Rev W”: Revision identifier (“W”) specifying hardware updates—including improved signal filtering, extended temperature tolerance, and enhanced compatibility with later SLC 500 firmware versions (e.g., Rev 15+).
- The designation aligns with Allen-Bradley’s legacy naming convention for analog I/O, where “3283” denotes 16-channel functionality and “C” indicates standard industrial voltage/current input support.
2. Product Description
The 3283C Rev W is an industrial-grade analog input module engineered by Allen-Bradley for high-precision acquisition of analog signals in legacy PLC-5 and SLC 500 control systems across manufacturing, food & beverage, and water/wastewater industries. As a critical front-end component for process monitoring, its core functions include:
- Capturing 16 independent analog input signals from field devices (e.g., pressure transducers, thermocouples, flow meters) with 12-bit resolution, supporting both voltage (0–10V DC) and current (4–20mA DC) input types.
- Filtering electrical noise via configurable hardware filters (10Hz–1kHz cutoff) to eliminate interference from nearby motors or power lines, ensuring stable signal transmission to the PLC
