The Allen-Bradley 1766-L32BWAA is a MicroLogix 1400 Programmable Logic Controller. It comes with the EtherNet/IP network, online editing capabilities, and a built-in LCD with enhanced network capabilities. There is also a backlight on the LCD to set the network configuration and view the controller and I/O status. The 1766-L32BWAA controller requires 120 to 240 Volts AC input power and it 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 Volts DC inputs, 12 relay outputs, and 6 analog (12 bits) I/O points with 4 inputs, 2 outputs. It can be expanded with as many as seven 1762 expansion I/O modules. It has dimensions of 3.5 x 7.08 x 3.43 inches and it weighs 2 pounds.

For communication, the 1766-L32BWAA 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. For installation, it has the panel or DIN-rail mounting options with an open enclosure. It is suitable for use in a clean and dry industrial environment with circuits not exceeding Over-Voltage Category II.
