Product Description
The Allen-Bradley 1756-L83EXT is a ControlLogix-XT 5580 series controller featuring 10 MB of user memory (expandable to 2 GB with optional non-volatile memory). It operates with a current draw of 1.2A at 5.1V DC and 5.0mA at 1.2V DC, dissipates 6.2 Watts of power (21.2 BTU/hour thermally), and provides 50V continuous isolation for its USB and Ethernet ports to the backplane. It withstands a 1000V AC test for 1 minute. Weighing 0.394 kg, this chassis-based module operates between -25 and 70 degrees Celsius (specifically in Series C XT chassis) and can be stored between -40 and 85 degrees Celsius. It tolerates 5-95% non-condensing humidity, 2g vibration (10-500 Hz), and 30g shock (operational and non-operational). This open-style controller uses wire category 3 for USB and category 2 for Ethernet, and is certified to CSA, CE, RCM, Ex, IECEx, FM, cULus, KC, and EAC standards, supporting relay ladder logic, structured text, sequential function chart, and function block diagram programming.
Is Your Device Showing These Signs?
The Allen Bradley 1756-L83EXT ControlLogix controller commonly requires repair due to power supply failures, resulting in system downtime. Issues include corrupted firmware requiring reflashing, damaged communication ports affecting network connectivity, and memory module failures leading to program loss. Backplane connector damage prevents proper module communication, and CPU overheating necessitates thermal paste replacement and fan maintenance. Resolving these problems restores optimal PLC performance and prevents further system instability.
