The Allen-Bradley 1766-L32BXBA is a MicroLogix 1400 Controller. It combines EtherNet/IP, online editing capabilities, and a built-in LCD with a high I/O count and enhanced network capabilities into one controller. It also features a backlight on the LCD for setting network configuration. The 1766-L32BXBA controller requires a 24 Volt DC input power and has battery-backed RAM. It supports 32 digital I/O points with 12 digital fast 24 Volt DC inputs, 8 digital 24 Volt DC inputs, 6 relay outputs, 3 fast 24 Volt DC outputs, 3 normal 24 Volt DC outputs and 6 analogs (12 bits) I/O points with 4 inputs and 2 outputs. It can connect to up to seven 1762 expansion I/O modules for further expansion.
It has measures 3.5 x 7.08 x 3.43 inches and weighs 2 pounds. For communication, it 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 and an open enclosure. It is suitable for use in a clean, dry, industrial environment with circuits not exceeding Over Voltage Category II. The 1766-L32BXBA controller’s Ethernet port provides DNP3 protocol support as well as a web server and email capabilities. Its 2 Serial ports have DH485/DF1/Modbus RTU/DNP3/ASCII protocol support. It has up to 6 embedded 100 kHz high-speed counters (only for controllers with DC inputs). The 1766-L32BXBA also has 20 KB of memory for user programs and data.
