The Allen-Bradley 1766-L32BXB is a part of the MicroLogix 1400 Programmable Logic Controller series. It features EtherNet/IP, online editing capabilities, and a built-in LCD that has enhanced network capabilities. The LCD also features a backlight for setting network configuration and viewing the controller and I/O status. The 1766-L32BXB controller requires 24 Volts DC input power and has battery-backed RAM. It supports 32 digital I/O points which are 12 digital fast 24 Volts DC inputs, 8 digital 24 Volts DC inputs, 6 relay outputs, 3 fast 24 Volts DC outputs, and 3 normal 24 Volts DC outputs. It has a dimension of 3.5 x 7.08 x 3.43 inches and a weight of 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. The 1766-L32BXB uses RSLogix 500/Micro programming software (Version 8.1 and above) for programming. For installation, it has Panel or DIN-Rail mounting options and an open enclosure. It is suitable for use in clean, dry, industrial environments with circuits that do not exceed Over Voltage Category II. The 1766-L32BXB controller has various enhanced features like an Ethernet port with DNP3 protocol support and email capabilities. It also has 2 Serial ports with DH485/DF1/Modbus RTU/DNP3/ASCII protocol support, up to 6 embedded 100 kHz high-speed counters (on DC controllers), and a 20 KB memory for user data.
