Specification

SEODescription

The Allen-Bradley 1761-L16BWA, part of the MicroLogix 1000 series, is a compact PLC designed for small-scale automation. It features 16 built-in I/O points (8 digital inputs and 8 relay outputs), supporting direct connection to expansion modules like the 1762 series for additional I/O flexibility. The unit operates on 24V DC and functions within a temperature range of 0°C to 55°C, making it suitable for industrial environments such as packaging, material handling, and HVAC systems. Communication interfaces include RS-232 and DH-485 protocols for integration with HMI devices or SCADA systems. Its key advantages include rugged construction, easy programming via RSLogix Micro, and cost-effectiveness for basic control tasks. However, limited memory and lack of Ethernet connectivity may restrict scalability in complex applications. The 1761-L16BWA excels in reliability for standalone operations where space and budget constraints exist.
