The Allen-Bradley 1769-L18ER-BB1B provides 512 KB of user memory within the CompactLogix 5370 L1 platform. It supports Logix-based automation programming for compatible industrial machine control and process sequencing applications.
The controller includes 16 sinking 24 VDC digital inputs and 16 sourcing 24 VDC digital outputs. These embedded I/O points support direct connections to compatible sensors, switches, relays and other industrial control devices.
Two integrated Ethernet ports support EtherNet/IP communication and linear or Device Level Ring network arrangements. Both ports operate through the embedded switch and share a single controller IP address, with support for up to eight EtherNet/IP nodes.
The integrated POINTBus backplane supports up to eight compatible 1734 POINT I/O expansion modules, providing flexibility to increase local digital or other supported I/O capabilities as application requirements develop.
The controller uses a nominal 24 VDC embedded power supply and supports industrial Secure Digital storage through the 1784-SD1 and 1784-SD2 memory cards. The controller design does not require a battery for program retention.
The DIN rail-mounted, open-style controller has a 100 mm module width, 130 mm body height and 105 mm depth. The documented operating temperature range of -20°C to +60°C supports appropriately designed industrial control cabinet installations.

What is Allen-Bradley 1769-L18ER-BB1B?
Allen-Bradley 1769-L18ER-BB1B is a CompactLogix 5370 L1 programmable automation controller with 512 KB user memory, 32 embedded digital I/O points, two EtherNet/IP ports and support for up to eight local 1734 POINT I/O expansion modules.
How much user memory does 1769-L18ER-BB1B provide?
The controller provides 512 KB of user memory for compatible Logix control applications. Application memory requirements should be checked against the program size, tag configuration and selected controller firmware.
How many built-in inputs and outputs does 1769-L18ER-BB1B have?
The controller includes 16 sinking 24 VDC digital input points and 16 sourcing 24 VDC digital output points, providing 32 embedded digital I/O points in total.
What power supply does 1769-L18ER-BB1B require?
The embedded power supply operates at nominal 24 VDC, with a specified input range of 10-28.8 VDC. External power supply wiring and isolation requirements vary by controller hardware series, so the applicable installation manual must be consulted.
How many Ethernet ports does 1769-L18ER-BB1B provide?
It has two built-in EtherNet/IP ports. The ports are connected through the controller embedded Ethernet switch, share one IP address and support compatible linear or Device Level Ring network topologies.
How many EtherNet/IP nodes does this controller support?
The 1769-L18ER-BB1B supports up to eight EtherNet/IP nodes. The documented controller connection capacity is 256, although node count and controller connections represent different configuration limits.
Can 1769-L18ER-BB1B be expanded with additional I/O modules?
Yes. The controller supports up to eight compatible 1734 POINT I/O modules on its local POINTBus backplane. Expansion module selection must consider supported firmware, available backplane current and field power requirements.
What is the difference between 1769-L18ER-BB1B and 1769-L18ERM-BB1B?
Both controllers belong to the CompactLogix 5370 L1 family and provide 512 KB user memory, but the 1769-L18ERM-BB1B adds integrated motion capabilities over EtherNet/IP. The 1769-L18ER-BB1B does not provide that integrated motion functionality.
What programming software is used with 1769-L18ER-BB1B?
The controller is programmed using compatible versions of Studio 5000 Logix Designer or earlier RSLogix 5000 software. The engineering software version must be compatible with the installed controller firmware revision.
Does 1769-L18ER-BB1B require a battery?
No. CompactLogix 5370 controllers use internal energy storage rather than a conventional memory-retention battery. The controller also supports removable Secure Digital cards for nonvolatile storage.
What are the dimensions and operating temperature of 1769-L18ER-BB1B?
The controller has a 100 mm width, 130 mm body height and 105 mm depth, with an overall mounting height of approximately 144 mm. Its documented operating temperature range is -20°C to +60°C. Adequate cabinet clearance and environmental protection are required.
What should be checked before ordering 1769-L18ER-BB1B?
Verify the exact catalog number 1769-L18ER-BB1B, hardware series, controller firmware revision, 512 KB memory capacity, 24 VDC power requirements, embedded 16-input and 16-output configuration, EtherNet/IP network compatibility, 1734 POINT I/O expansion requirements, SD card configuration, programming software compatibility and installation dimensions. When replacing an existing controller, also confirm the application backup and hardware-series-specific power wiring requirements.
