The Allen-Bradley 1766-L32BWA is a part of the MicroLogix 1400 Programmable Logic Controller series. It combines the features of previous MicroLogix 1100 controllers, such as EtherNet/IP, online editing capabilities, and an LCD with enhanced features. It also features a backlight on the LCD for setting network configuration, viewing the controller and I/O status, monitoring, and manipulation. The 1766-L32BWA controller requires 120 to 240 Volt AC input power and has battery-backed RAM. It supports 32 digital I/O points that consist of 12 digital fast 24 Volts DC inputs, 8 digital normal 24 Volt DC inputs, and 12 relay outputs. It can be expanded with up to seven 1762 expansion I/O modules. It has dimensions of 3.5 x 7.08 x 3.43 inches and a weight of 2 pounds.
For communication, the 1766-L32BWA has an isolated RS-232/485 port, an Ethernet port, and a non-isolated RS-232 port. It also has an embedded real-time clock to provide a reference for applications that need time-based control. It is programmed with RSLogix 500/Micro programming software (Version 8.1 and above). For installation, it has Panel or DIN-Rail mounting options with an open enclosure. It is suitable for use in a clean, dry industrial environment with circuits not exceeding Over Voltage Category II. The 1766-L32BWA controller has various enhanced features that its predecessors lack. The Ethernet port provides DNP3 protocol support as well as a web server and email capabilities. It has 2 Serial ports with DH485/DF1/Modbus RTU/DNP3/ASCII protocol support. It has up to 6 embedded 100 kHz high-speed counters (only for DC controllers). It also has 20 KB of memory for user programs and data.
