The Allen-Bradley 1769-L32E CompactLogix Controller is a powerful controller. The package also contains a built-in Ethernet/IP port, enabling the controller to efficiently transmit in sync with distributed I/O modules over an Ethernet network. The Ethernet communication modules enhance the configuration and data gathering functions of the controller and offer a greater degree of data exchange and control. System-shared tags can also be broadcasted and received over these networks. The I/O modules can be mounted on the rack in either a single-bank or a multi-bank system. The single-bank system can have a maximum of 8 I/O modules between the power supply and the end cap, whereas the multi-bank system can have a maximum of 8 I/O modules on either side of the additional power supply. The Allen-Bradley 1769-L32E controller can provide for up to 6 tasks and 16 I/O modules. It is equipped with a fully isolated RS-232 port. With a user memory of 750 kiloabytes and a serial port, this controller is both versatile and highly effective. When configured in user mode, the serial port can also be used to interface with ASCII devices. The 1769-L32E controller is user-friendly and allows for priority levels ranging from 1 to 15 to be assigned to specific tasks that are to be performed by the system. The controller also has a Channel 0 push button that can be used to activate its default communication mode. A 1769-BA battery is provided with the controller and can be used for durations ranging from 9 months to 26 months depending on the operating temperature and frequency of usage.

The Allen-Bradley 1769-L32E is a Programmable Automation Controller (PAC) module. This is a modular controller that is included in the CompactLogix 1769 series. Modules in this series serve as a migration platform for legacy PLC modules. It features one RS232 port and one Ethernet port for connectivity. The RS232 port transfers data at the rate of 19.2 Kilobytes per second but does not support handshaking. The port is also configurable as an ASCII protocol interface which allows the processor to connect to devices such as barcode scanners. This processor supports up to 16 Compact I/O modules. The number of modules can be increased using up to 3 additional I/O expansion banks that are connected using two expansion cables. The module has an internal memory capacity of 750 Kilobytes. The non-volatile memory capacity may be added to this processor using CompactFlash cards. Supported models include the 1784-CF64 and 1784-CF128 memory cards. The processor has a replaceable internal battery module with part number 1769-BA that is used to retain the user data stored in volatile memory. This processor module has a current draw of 850 milliamperes at an input voltage of 5 Volts Direct Current. The rated heat dissipation is 6.5 Watts. The module can be mounted using a DIN rail mount or by using panel mounting. The 1769-L32E has a shipping weight of approximately 2 pounds. The dimensions are 8 x 8 x 5 inches.
