1763-L16DWD | Allen-Bradley MicroLogix 1100 Controller, 12/24VDC, 16-Points

The 1763-L16DWD is a programmable logic controller (PLC) used for industrial automation and process control applications. It belongs to the MicroLogix 1100 family and integrates both discrete and analog I/O for versatile use. This controller enables monitoring and control of input/output devices, such as sensors, relays, and actuators. It supports high-speed counting and analog signal processing, making it suitable for complex control tasks. With built-in Ethernet and RS-232/485 ports, it allows for flexible communication and integration with HMIs, SCADA, and other controllers.

The controller operates on a DC voltage supply, specifically in the range of 12 to 24 Volts DC. This allows for flexible integration in both mobile and stationary control panels. The low-voltage requirement makes it compatible with battery-powered or industrial-grade power supplies. The device also handles inrush currents of up to 15 Amps, which should be considered when designing power circuits. Proper voltage regulation ensures optimal operation and prevents input faults.

The 1763-L16DWD has 10 digital inputs (including 4 high-speed counters), 2 analog voltage inputs (0–10 VDC), and 6 digital relay outputs. This combination provides basic yet flexible control for monitoring and actuating devices. The high-speed inputs support encoder signals and fast counting applications. Analog inputs allow for process monitoring such as pressure or temperature via 0–10 V sensors. The relay outputs are electrically isolated and support a range of voltages. This mix of I/O makes it ideal for hybrid systems with both analog and digital signals.

Yes, the 1763-L16DWD supports expansion using MicroLogix 1762 I/O modules. You can connect up to four expansion modules to increase the I/O count. These can include additional digital inputs/outputs, analog inputs/outputs, and specialty modules. The modules connect directly to the right side of the base controller. Expansion enables the device to adapt to growing system requirements. It provides modular flexibility without needing to upgrade to a larger PLC.

No, the 1763-L16DWD controller has been officially discontinued by Rockwell Automation as of April 30, 2022. It is no longer available for sale, and customers are encouraged to transition to alternative products. The recommended replacement is from the Micro800 controller family, which offers modern features and broader scalability. Although discontinued, technical documentation and limited support may still be available for legacy installations. Users should plan migration strategies to ensure long-term system reliability and compatibility.
