About 1769-L23E-QB1B
The Allen-Bradley CompactLogix controller with catalog number 1769-L23E-QB1B is a CompactLogix Packaged controller. This controller offers cost-effectiveness as the embedded functions allows the controller to function a complete Programmable Logic Controller (PLC) capable of discrete automation. It has a compact assembly that allows it to be fitted in tight spaces while the modern connectivity ports allow the device to be integrated to a much larger control system network. The 1769-L23E-QB1B memory has 512 Kbyte integrated volatile memory which is maintained by a battery with catalog number 1769-BA. This battery has status indicator that allows the user to be notified when replacement is necessary. This battery has variable life expectancy depending on the temperature and usage of the controller. If the controller is always OFF, battery life range from 9 months to 14 months. A controller supplied with power 8 hours per day and 5 days per week, battery expectancy lasts from 12 month to 18 months. If the controller is operating 16 hours per day, 5 days per week, battery life is further extended to an expectancy of 16 months to 26 months while no battery drain is expected when the controller is always ON. From the first existence of low battery indicator, it takes 8 days for the battery to completely drain if the environmental temperature is 60 C or 140 F and 25 days if operating temperature is 25 C or 77 F. The controller is embedded with discrete Input and Output channels only however, it supports up to Two (2) 1769 Compact I/O modules for local expansion. It also supports Distributed I/O architecture using Allen-Bradley Distributed I/O devices such as Point I/O and Flex I/O product families over Ethernet. The embedded input amount to Sixteen (16) 24VDC sinking input channels, compatible for interfacing binary operating devices such as mechanical and electrical switches, pushbutton devices and other similar operating devices. The embedded output channels are Sixteen (16) 24VDC sourcing output channels capable of driving 24VDC loads such as solenoid actuated devices, relay coils, Pilot lamps, buzzer, sire, horn, valves and other filed instruments. This control actions may be designed in manual or automatic mode, depending on the defined user logic. It support offline and online programming as well as provided with maintenance and commissioning tools for fast engineering of the controller. The RSLinx is used to define the communication settings of the embedded One (1) Ethernet communication port and One (1) RS232 communication port that supports ASCII, DF! Full Duplex, DF1 Half Duplex and DFI master and slave as well las DH485 communication protocols.F.A.Q for 1769-L23E-QB1B
| Q: 1. Does the 1769-L23E-QB1B include embedded analog input and high-speed channels? | A: No, only 24VDC discrete input and output channels are available with the 1769-L23E- QB1B. |
|---|---|
| Q: 2. What are the communication ports embedded with the 1769-L23E-QB1B? | A: The 1769-L23E-QB1B includes One (1) RS232 and One (1) Ethernet communication port. |
| Q: 3. How many 1769 Compact I/O modules does the 1769-L23E-QB1B support? | A: The 1769-L23E-QB1B supports installation of up to Two (2) 1769 Compact I/O channels |
PDFsupply Tech
The 1769-L23E-QB1B is a CompactLogix packaged controller that features a total of 32 I/O channels composed of 16 24VDC inputs and 16 24VDC outputs. This controller is capable of performing Discrete automation out of the box with support for expansion. Compared to the 1769-L23E-QBFC1B with embedded analog channels, use the 1769-L23E-QB1B if the existing application requires discrete automation only.
