The Allen-Bradley 1756-L1M1 is a versatile ControlLogix 5550 controller featuring 500 Kbytes of data and logic memory supplemented by 150 Kbytes of I/O memory, housed in an open-style enclosure. Notable for its adaptability, it can fit into any slot within a chassis and operates efficiently within a temperature range of 0 to 60 degrees Celsius, supporting a non-condensing relative humidity level between 5% and 95%. Primed for robust performance, it endures vibrations up to 2.0 G from 10 to 500 Hz and has an operating shock capacity of 30 G peak for 11 milliseconds. The controller draws a backplane current of 950 mA at 5.1V, offering a module power of 5.33 W, and requires a 1756-BA1 lithium battery for smooth operation, while programming is facilitated via the 1756-CP3 serial cable.
