The Allen-Bradley Company introduces the model 1769-L33ER, which is a 5370 CompactLogix controller. This CompactLogix is dedicated to creating communication with the controls or any other device that needs it, all this through an Ethernet port. As for its composition, this model has 2M of memory in its internal structure. It also has a non-volatile memory card of 1GB that can be expanded to 2MB. Moreover, the 1769-L33ER CompactLogix 5370 controller has a draw current of 5 Volts DC at 560 milliamperes across four (4) power supply modules and has a maximum power dissipation of 4.5 Watts. As for its support, it can work with up to sixteen (16) I/O modules with a maximum of three I/O banks connected by proper expansion cables. This model can be mounted using either a DIN rail or panel mounting, and It has a 500 milliampere @ 5 VDC back-plane current draw and maximum bus insulation of 30 Volts.

The 1769-L33ER CompactLogix 5370 controller weighs 0.31 Kilograms (0.68 Pounds). This model can operate in temperatures from 0 to 60 degrees Celsius and has a -40 to 85 degree Celsius storage temperature. As for humidity, its resistance range is from 0 to 95%, and you can use various power supplies such as the 1769-PA2, the 1769-PA4, and the 1769-PB4. It also comes with a single USB interface which is suitable to serve as a backup communication protocol. This type of USB interface can be used in general for primary configuration and troubleshooting purposes.

The 1769-L33ER is a compact Logix controller made by Allen-Bradley. This controller is included in the CompactLogix 5370 L3 controller series. It offers connectivity with controllers or other devices using an integrated dual Ethernet port that supports auto-negotiation features and offers a data transfer rate of 10/100 megabits per second. The port may serve as an embedded switch. Up to 32 nodes may be connected at a time, a USB port is also provided. The provided integrated user memory capacity is 2 Megabytes. An additional non-volatile memory storage is provided by the included optional memory card with a data storage capacity of 1 gigabyte. This is expandable up to 2 gigabytes. The controller is able to support up to 16 I/O modules with the capability to connect up to 3 I/O banks using expansion cables. The module has a current draw rating of 560 milliamperes at 5 Volts Direct Current across 4 power supply modules. The module is rated for a power dissipation of 4.5 Watts at maximum. The module has a maximum bus isolation voltage of 30 Volts. Supported power supply modules include the 1769-PA2, 1769-PA4, and 1769-PB4. The module may be mounted using a DIN rail mounting or by using a panel mounting. The weight of the module is approximately 0.31 kilograms (0.68 pounds). This controller can connect to I/O modules via DeviceNet using a 1769-SDN module.
