Description

Allen‑Bradley 1769-L33ER CompactLogix 5370 PAC Controller, 2MB, Dual EtherNet/IP with DLR

Product Description

The 1769-L33ER is Rockwell Allen‑Bradley CompactLogix 5370 series mid-range programmable automation controller (PAC). It is equipped with 2MB user memory, dual built-in EtherNet/IP ports supporting DLR (Device Level Ring) fault-tolerant ring network, one USB programming port and an SD card slot for program backup. It can drive up to 16 local 1769 Compact I/O modules with 3 expansion banks and supports maximum 32 EtherNet/IP nodes. It executes sequential logic, analog closed-loop regulation, alarm handling and tag communication tasks. It communicates with local I/O via CompactLogix backplane, connects HMI, remote I/O and upper SCADA through the dual EtherNet/IP port. It adopts compact DIN rail integrated design and is widely used for medium-sized skid and process automation projects.
