The 1769-L33ER controller belongs to the advanced CompactLogix 5370 product line from Allen-Bradley. This Programmable Automation Controller (PAC) is a cost-effective solution for medium-sized applications. It offers the powerful Logix platform capabilities in a modular, rackless design. Specifically, this controller provides an excellent balance of performance and flexibility for complex automation tasks.
The 1769-L33ER logic module comes equipped with 2 MB of user memory for handling substantial programs. It supports a maximum of 32 local I/O modules distributed across 3 I/O banks. This configuration provides significant expansion capability for growing systems. Furthermore, the controller manages up to 32 tasks and 100 programs per task.
Communication is a key strength of this model. The unit features two embedded Ethernet ports that act as a built-in switch. These ports support 10/100 Mbps data rates with auto-negotiation capabilities. They use the EtherNet/IP protocol for seamless integration with HMIs, SCADA, and DCS systems. Additionally, a single USB port serves as a fallback for primary configuration and troubleshooting.
The 1769-L33ER does not require a battery for memory retention. It uses an internal energy storage solution to retain 1 MB of user memory. For non-volatile storage, the controller ships with a 1784-SD1 card offering 1 GB of memory. You can optionally upgrade this to the 1784-SD2 card for 2 GB of storage. The backplane current draw is 500 mA at 5 Volts DC. Its maximum power dissipation is 4.5 Watts.
This controller is designed for demanding industrial environments. Its operating temperature range is from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). The storage temperature ranges from -40 to 85 degrees Celsius. It also operates within a non-condensing relative humidity range of 0 to 95%.
Moreover, the 1769-L33ER demonstrates robust resistance to physical stress. It withstands an operating vibration of 5 g at 10-500 Hz. The shock rating is 30 g for panel mounting and 20 g for DIN Rail mounting. Therefore, panel installation offers superior shock resistance for high-vibration applications.
Proper installation ensures the reliable operation of the 1769-L33ER PAC. You can mount the unit on a standard DIN Rail or directly onto a panel. Unlike larger systems, it does not require an electronic rack or chassis. The system uses electronic keying to prevent incompatible device usage. You can select options like Compatible Module, Disable Keying, or Exact Match.
Wiring must comply with specified standards. Use copper wire rated for 90 degrees Celsius. Solid wire sizes from 22 to 14 AWG are acceptable. For stranded wire, use sizes from 22 to 16 AWG. The controller requires a compatible power supply, such as the 1769-PA2, 1769-PB2, 1769-PA4, or 1769-PB4. The power supply distance rating is four slots.
