Manufacturer: Rockwell Automation
Brand: Alan Bradley
Part Number/Catalog number: Model 1756-L55M13
Series :ControlLogix
Module type: Processor module
The Allen-Bradley 1756-L55M13 is an A-series ControlLogix 5555 controller. While this particular controller has no non-volatile memory available, it does have 1.5 MB of data and logic memory and 208 KB of I/O memory available. The 1756-L55M13 controller weighs 0.35 grams or 12.5 ounces. It has no case type rating because it is an open controller.
It also supports the following communication options: DeviceNet, ControlNet, Ethernet/IP, Universal Remote I/O Serial, Data Highway Plus, Modbus via ladder routine, SynchLink, and DH-485.
The backplane currents of the 1756-L55M13 are 0.014A (24V DC) and 1.23A (5.1V DC). Its thermal dissipation is 19.1 BTU/hr, while its power consumption is 5.6W. It has a basic insulation type and a continuous isolation voltage of 30V, and has also been tested to withstand 707V DC for 60 seconds. The 1756-L55M13 controller has conducted RF immunity of 10V rms and 1 kHz sine wave 80%AM in the 150 kHz to 80 MHz range.
The storage temperature of the controller is between -40 and 85 degrees Celsius and the operating temperature is between 0 and 60 degrees Celsius. The non-condensing relative humidity ranges from 5% to 95%. It has a vibration of 2 g at 10 to 500 Hz, a working shock of 30 g and a non-working shock of 50 g.
The controller has a replaceable battery, but only when needed, and is only compatible with the 1756-BA1 lithium battery. It can only be connected using a 1756-CP3 or 1747-CP3 programming cable. The 1756-L55M13 controller can be used in a redundant controller system, but it needs to be in the same ControlNet network.
