The Allen-Bradley 1769-L23E-QB1B compact controller is an PLC with a built-in power supply and a 512 KB memory that runs on the RSLogix5000 software. The 1769-L23E-QB1B controller does not support compact flash cards but it can communicate with other machines through a single Ethernet/IP port and through an RS-232 (DF1 or ASCII) serial communication port. It is an embedded compact Logix controller with 16 DC inputs and 16 DC outputs. The 1769-L23E-QB1B module expansion setup can include up to 3 Allen-Bradley 1769 modules and its size can only be limited by the amount of current that each additional module draws. It has an embedded 24 Volts DC power supply and a 1000 milliamps BUS current at 5 Volts DC. The 1769-L23E-QB1B controller has a request packet interval (RPI) speed of approximately 1.0 millisecond of scan time across 1 to 4 modules. It comes with an Allen-Bradley 1769-BA replaceable battery.
At 24 Volts DC, the Allen-Bradley 1769-L23E-QB1B compact controller has a drawn current of 700 milliamps and it dissipates 7 Watts of power. Devices can be connected to the 1769-L23E-QB1B through the Allen-Bradley 1756-CP3 or 1747-CP3 serial cables. Additional embedded features of the 1769-L23E-QB1B drive include 16 inputs and a 24-Volt voltage category. It operates at 10 to 30 Volts DC at 30 degrees Celsius (86 degrees Fahrenheit). Additional embedded features include an input impedance of 3 kiloohms, a maximum inrush current of 250 milliamps, an off-state voltage of 5 Volts DC maximum, and an off-state current of 1.5 milliamps. The 1769-L23E-QB1B compact controller also has embedded output features which are a 16-unit output, an output delay time of 0.1 milliseconds, and a maximum leakage current of 1.0 milliamps at 26.4 Volts DC. The current across each module of the 1769-L23E-QB1B controller is rated at 4.0 Amps at 60 degrees Celsius (140 degrees Fahrenheit). The 1769-L23E-QB1B controller has an approximate weight of 0.91 kilograms (2 pounds) and it can be mounted on a DIN rail or on a panel mounting base.
