Products Description

The 1769-L23E-QB1B is an Allen-Bradley packaged controller. This controller is part of the CompactLogix 5370 L2 product category that comes with embedded features, enabling this controller to function out of the box. It has integrated power supply that is operated by nominal supply voltage of 24VDC which supplies the necessary backplane power to the integrated modules of the controller.

In addition, the 1769-L23E-QB1B has built-in 16 channels of 24VDC Discrete inputs and 16 channels of Discrete outputs as well. I/O expansion is allowed by installation of additional Three (3) 1769 Compact I/O modules to custom fit this controller to the application requirement. It is also provided with 512KB user memory which can accommodate up to any combination of 32 periodic or continuous with 100 programs per task.

For controller communication, the 1769-L23E-QB1B feature a single Ethernet port and a USB interface. Both ports support high speed communication, with ethernet supporting 10/100 Mbps transmission rate and an RS232 communication interface that supports DF1, DH485 and ASCII interface. These ports specifically support communication with Supervisory Control and Data Acquisition (SCADA), Human Machine Interface (HMI), and controllers within the same Ethernet and RS232 connections.

For Version 17.01.02, revision 17.012; 19.01.00 revision 19.015; For 20.01.00, revision 20.013.

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. 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.
