1766-l32bwa_a_110_240v_ac_power

Product Overview

Allen-Bradley 1766-L32BWA is a 32-point controller within the Rockwell Automation MicroLogix 1400 series, featuring 110/240V AC power supply and relay outputs. As a compact programmable logic controller, 1766-L32BWA integrates a processor, embedded I/O, communication ports, and a backlit LCD into a single unit, targeting small machinery control and standalone automation applications where panel space is limited and AC power is readily available .

The I/O configuration of 1766-L32BWA comprises 20 digital inputs and 12 relay outputs. The input group is subdivided into 12 fast 24V DC inputs and 8 standard 24V DC inputs, with the high-speed channels supporting up to 100 kHz operation for pulse counting or encoder-based position feedback . The 12 relay outputs provide dry-contact switching suitable for direct interface with contactors, solenoid valves, and indicator lamps, eliminating the need for external interposing relays in many AC or DC load applications .

A significant distinction of the MicroLogix 1400 platform is its communication architecture. 1766-L32BWA provides an isolated RS-232/RS-485 combo port, a non-isolated RS-232 port, and an embedded 10/100 Mbps EtherNet/IP port . The Ethernet interface supports not only EtherNet/IP messaging but also web server functionality, email capability, Modbus TCP/IP, and DNP3 over IP, enabling 1766-L32BWA to serve as a capable edge controller in modern networked architectures while retaining the serial connectivity required for legacy devices and HMI panels .

Rockwell Automation lists 1766-L32BWA as Active Mature, indicating continued availability and support though not the primary focus of new development . For existing MicroLogix 1400 installations, this status means the controller remains a viable spare-part and maintenance option, while new designs would typically consider the Micro850 or CompactLogix families.
