1761-L32BWA

The 1761-L32BWA is a Programmable controller manufactured by Allen Bradley, a division of Rockwell Automation. The 1761-L32BWA is classified under the MicroLogix 1000 series. The 1761-L32BWA mounting methods support DIN rail or screw mounting. The 1761-L32BWA features up to Twenty (20) discrete input points and Twelve (12) relay outputs. This controller has built in AC Power Supply. This Allen Bradley programmable controller features a small and economic design. The unit measures only 7.87 x 2.87 x 3.15 inches. It is capable of connecting in peer-to-peer connection, through the integrated RS232 port. The 1761-L32BWA is an affordable controller small enough to fit into tight spaces and is a powerful module with the ability to accommodate several application types. The 1761-L32BWA has the ability to expand as the user’s needs continue to change. It helps the user to achieve high-level control in different applications. The MicroLogix 1000 controllers come with different advantages. These controllers feature a preconfigured 1KB program with data memory that eases the configuration process. The unit also supports fast processing, allowing for a typical throughput time of about 1.5 milliseconds for the 5000-instruction programs. The 1761-L32BWA features a built-in EEPROM memory that has the ability to retain all of the user’s ladder logic and data in case the controller loses power or eliminates the need for a battery backup or a separate memory module. Through the RS-232 communication channel that is provided on the module, the 1761-L32BWA supports simple connectivity to a PC. This allows the user to perform program uploading and downloading and supports monitoring with multiple protocols.

The 1761-L32BWA is a MicroLogix controller. This is a compact controller that is suitable for use in automating simple machine and process control requirements. The 1761-L32BWA is manufactured by Allen-Bradley that is a Programmable Logic Controller (PLC).

This PLC unit is capable of handling up to Twenty (20) discrete inputs. These input channels support sinking and sourcing configuration and may be provided with voltage signal of 24VDC. Discrete inputs represent the state of field devices such as switches and relays. It also has Twelve (12) contact outputs with ratings of 24-125VDC / 120/240VAC. Discrete outputs are used to energize external loads to implement control.

Though the integrated RS232 communication port, the controller may be used to communicate with DF1 protocol enabled devices such as Human Machine Interfaces (HMI), Supervisory Control and Data Acquisition (SCADA), protocol gateways and communication protocol converters. This communication port may also be configured with DH485 communication. For connecting to a DH485 network, the Allen-Bradley 1761-NET-AIC may be used.

This controller is capable of implementing PLC instructions such as Bit logic, Timers, Counters, Flip-Flops, Comparator instructions, Math Operations, Data Handling, Program control, Register manipulation and Messaging instructions.

Alternatively, this PLC device may also be configured using the MicroLogix 1000 Hand-Held Programmer (HHP).
