Allen-Bradley 1756-L65 is a B-series ControlLogix controller. The 1756-L65 has a built-in RS-232 serial port, as well as 32 MB of user memory for data and logic and 478 kb of I / O memory. You can also use this controller to install optional non-volatile memory. However, only 128 MB CompactFlash 1756-CF128 memory cards can be installed. The 1756-L65 also has a replaceable battery, but it can only be replaced when needed. The battery compatible with this controller is only the 1756-BA2 lithium battery. ControlLogix chassis compatible with this controller are 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17.
The 1756-L65 has a maximum analog I / O of 4000, a maximum digital I / O, and a maximum total I / O of 128,000. It consumes 1200 mA at 5.1V DC and 14 mA at 24V DC. The 1756-L65 consumes 3.5 W and dissipates 11.9 BTU / hr. It also has a continuous isolation voltage of 30V. The controller was also type tested at 720 V DC for 60 s.
The 1756-L65 controller has an operating temperature range of 0 to 60 degrees Celsius and a 1756-L65 storage temperature range of -40 to 85 degrees Celsius. The 1756-L65 also has an upper ambient air temperature of 60 degrees Celsius and a non-condensing relative humidity range of 5% to 95%. The controller has a vibration of 2 g at 10 to 500 Hz, an operating shock of 30 g, and a non-operation shock of 50 g.
Like other ControlLogix 5560s, the 1756-L65 also has three main controller tasks, namely 100 programs / tasks, 32 tasks and event tasks: all event triggers. Available communication options for this controller include DeviceNet, ControlNet, EtherNet / IP, Remote I / O, Data Highway Plus, SynchLink, and third-party process and device networks. The 1756-L65 controller also has serial port communication. These ports include ASCII, DF1 radio modem, DF1 full / half duplex, Modbus and DH-485 via logic. The 1756-L65 has support for up to 250 controller connections. ability.
It should be noted that given that the same project has been loaded into these controllers, the scan time of this controller may be slower than other ControlLogix 1756-L6x controllers.
