The 1766-L32BXBA is a MicroLogix Programmable Logic Controller (PLC). This controller features is a compact controller type that is a cost-effective electronic device for implementing automation of small applications in various industrial applications. This controller also supports expansion where up to Seven (7) 1762 MicroLogix I/O expansion module may be installed. This controller is also equipped with multiple communication channels, allowing simultaneous communication with multiple partners such as Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA), Distributed Control Systems (DCS), OLE for Process Control (OPC) servers, protocol converters, gateways, database, reporting tools and other industrial applications. This embedded discrete I/O of this controller amounts to 32 I/O which comprise of Twelve (12) Fast 24VDC, Eight (8) Normal 24VDC, Six (6) Relay, Three (3) Fast DC, and Three (3) Normal DC outputs. As indicated by the letter ÒAÓ in the part number, this controller has embedded Two (2) Voltage inputs and Two (2) Voltage outputs. The analog input channelÕs compatible voltage range is 0-10VDC with resolution of 12-Bit unsigned integer. The embedded channels do not support loop power which means an external power supply must be installed to power the connected devices. Analog inputs are converted to a 12-bit unsigned integer, which is also known as raw data. This raw data is further conditioned using analog scaling instructions and saved in data formats such as Engineering units, Raw/Proportional, Scale for PID, and Percent Range. Analog inputs support 2-wire, 3-wire and 4-wire transmitters. The analog outputs channels are also 12-bit resolution channels with output voltage range of 0-10VDC. Use the analog outputs to control modulating devices such as control valves and Variable Frequency Drives (VFD). The integrated communication channels of this module include an isolated RS232/RS485 combo port, non-isolated RS232 communication port and Ethernet Communication port. Supported protocols by the Serial communication port are DF1 Full and Half duplex, DNP3, MODBUS RTU, ASCII and DH485 while with Ethernet, MODBUS TCP, DNP3 and Ethernet I/P are supported. The internal memory of the controller amounts to 20KB, backed-up by 1746-BA battery to retain the memory. The internal memory is allocated for 10KB user program and 10KB Program data. The controller has a battery to indicate battery charge. If the battery is drained, it must be replaced with active power supplied to the controller otherwise, the contents of the memory is erased. This controller also has a memory for data logging amounting to 128KB and 64KB for recipe. To prevent unwanted erasure of the program due to the battery being drained, install a 1766-MM1 memory module with 20KB memory as well. This memory module is a non-volatile memory that does not require a battery to retain its contents. The 1766-L32BXBA is also installed with a real-time clock. This component allows implementation of scheduled logic processing which is the typical approach in scheduling actuations of devices and equipment of the controlled process. This is typically implemented in the manufacturing, HVAC, Water and Waste Water applications with the primary intention of distributing equally the runtime of the equipment and devices aside from automated start-up and shutdown.
The Allen-Bradley 1766-L32BXBA is a MicroLogix 1400 Controller. This controller is designed for Power Supply input voltage of 24VDC with embedded Twelve (12) Fast 24VDC, Eight (8) Normal 24VDC, Two (2) Voltage inputs, Six (6) Relay, Three (3) Fast DC, Three (3) Normal DC outputs and Two (2) Voltage output channels. This controller has One (1) isolated RS232 / RS485 combo port, One (1) non-isolated RS232 communication port and One (1) Ethernet communication port.

F.A.Q for 1766-L32BXBA

Q: 1. Does this controller use battery to retain the contents of the controller memory? A: Yes, the battery is installed to the module. It has a replacement part number of 1747- BA.
Q: 2. How can I set the IP address of the controller?A: The IP address may be configured using BOOTP DHCP configuration tool.
Q: 3. How many expansion modules can I install with this controller?A: Up to Seven (7) 1762 MicroLogix expansion I/O may be installed with this controller.

The 1766-L32BXBA is a MicroLogix 1400 controller that has a total of 32 embedded discrete I/Os. Not included in this I/O count are the integrated analog input and output channels which are Two (2) Voltage input and Two (2) Voltage output. Analog channels are only present with controllers that ends with ÒAÓ or ÒAAÓ such as the 1966-L32BXBA. With the embedded analog channels, the controller is capable of manual and automatic control of analog control loop without installing an expansion module.
