Overview
Controller Processing and Memory
The 1769-L24ER-QB1B supports up to 32 controller tasks, with a maximum of 100 programs per task. Its 750 KB user memory provides storage for controller logic and application data. This configuration allows users to organize control routines into separate tasks and programs according to application requirements.
Communication Interfaces
The controller provides two Ethernet ports and one USB port. The Ethernet interfaces support EtherNet/IP communication, while the USB port provides a local connection for controller configuration and maintenance.
In addition, the supplied specifications identify DeviceNet as a communication option. However, they do not specify the required interface hardware or connection method. Therefore, confirm the DeviceNet configuration before selecting this controller for an existing network.
Expansion and Power Requirements
The controller supports up to four local expansion modules, allowing users to extend its I/O configuration. It draws 1.54 A at 5 VDC and 0.95 A at 24 VDC, with a maximum power dissipation of 12 W.
Meanwhile, the embedded power supply accepts an isolated 24 VDC input. The controller supports DIN rail or panel mounting, providing two installation options for control cabinet layouts.
