The 1761-L32BWA is a MicrolLogix Programmable controller manufactured by Allen Bradley/Rockwell Automation and part of the MicroLogix 1000 series. This unit supports sinking or sourcing configuration and has a power supply of 120 – 240 volts AC. The 1761-L32BWA controller also supports DIN rail mounting as well as mounting with screws. It features 24 volts DC input type and has up to 20 input points and a 12-point relay output built with an AC Power Supply. Other features of this module include a small and economical design, approximated dimensions of 7.87x2.87x3.15 inches, and it also offers several benefits to the operator. When connecting to a peer-to-peer network, the controller uses the RS-232 communication port. It also has a DeviceNet Interface, which is cheap, quick, and reliable to use, ensuring that the controller is installed and put I operation within the shortest time possible. Allen Bradley 1761-L32BWA MicroLogix programmable controller is affordable and small enough to fit in small spaces. Besides, it is a powerful module and can accommodate various types of applications. This controller is flexible and can expand according to the needs of the user. It is designed to help the operator to achieve high-level control in different applications. These controllers come with a preconfigured 1-kilobyte program with a data memory that makes the configuration process easy. Additionally, this unit supports fast processing and allows for a typical output time of approximately 1.5 milliseconds for 5000 instruction programs. It uses the RS-232 communication port to connect to a PC, and it enables the user to program the module, download and upload. The 1761-L32BWA controller also supports monitoring using multiple protocols.

The Allen-Bradley 1761-L32BWA is a PLC controller from MicroLogix 1000 controller series. The controller has 20 DC inputs and 12 relay outputs, and its size is 7.87 x 2.87 x 3.15 inches. The DC inputs can be configured as sinking or sourcing types. A portion of these points can be used for high-speed applications up to 6.6 kHz using a high-speed counter. The program is entered into memory using an external programming device. In case of power down, the controller keeps the last used program in EEPROM to continue the operation without losing its data. The relay outputs are a standard type with restrictions for maximum currents that are not equal for DC and AC operations. For 24 VDC switching, make/brake currents are maximum 1.2 Amps and 2 Amps if the load needs continuous current. If 120 VAC is used for output switching, then make/break currents are respectively 15 Amps and 1.5 Amps, and continuous current has a maximum value of 2.5 Amps. The 1761-L32BWA has embedded communication ports that can be used for RS-232, DH-485, or DF1 protocol. The controller is also able to connect to advanced communication networks, including the EtherNet/IP network, through the 1761-NET-DNI. The controller should be operated in an environment of 0 to 55 degrees Celsius (32 to 131 degrees Fahrenheit) for horizontal mounting and 0 to 40 degrees Celsius (32 to 104 degrees Fahrenheit) for vertical mounting.
