A-B 1756-L65

The Allen-Bradley 1756-L65 belongs to Series B of the ControlLogix controllers. ManufacturedbyRockwell Automation/Allen-Bradley, the controller has an inbuilt RS-232 serial port. It also has a32 MB user memory for both data and logic as well as 478 KB of I/O memory. If users like, theycan install a non-compulsory nonvolatile memory storage with the 1756-L65 controller. On theother hand, there is only a 128 MB CompactFlash memory card that can be installed on the1756-CF128 model. It comes with a battery which is replaceable but only when required. Theonly battery which is compatible with the 1756-L65 controller is a 1756-BA2 lithiumbattery. Some of the ControlLogix chassis that are compatible with the 1756-L65 controller include the1756-A7, 1756-A4, 1756-A17, 1756-A13, and the 1756-A10. The Allen-Bradley 1756-L65 has 4000maximum analog I/O and 128,000 maximum total I/O. The 1756-L65 controller has a current draw of 14 mA at 24 Volts DC and 1200 mA at 5.1 Volts DC. The controller has a power dissipationof 3.5 Watts and 11.9 BTU/hour thermal dissipation. Additionally, it has 30 Volts DC constant isolation voltage. This Allen-Bradley controller has been type-tested for 60 seconds at 720 Volts DC
