About
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-L32BWAAÂ 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 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.
The 1766-L32BWAA controller comes with an Ethernet port that 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, up to 6 embedded 100 kHz high-speed counters, and a 20 KB memory for user programs and data.
