Allen-Bradley 1756-0BV8S is A Series ControlLogix memory board. It can only be installed in ControlLogix 5550 controllers, such as 1756-L1, 1756-L1M1, 1756-L1M2, and 1756-L1M3 controllers. The memory board has 512 KB of extended memory and has an open chassis type rating. Note that only one memory board can be installed on a controller. You are advised to install the memory board into the chassis using a grounding wrist strap and a #2 Phillips screwdriver.

The 1756-0BV8S memory board operates at a temperature of 0 to 60 degrees Celsius. It also has a storage temperature range of -40 to 85 degrees Celsius. The relative humidity of the memory board is 5% to 95%, and there is no condensation. It also has a vibration of 2 g (from 10 to 500 Hz), a working shock of 30 g and a non-working shock of 50 g.

The memory board also has 1 set of Class A radiation and ESD immunity for 6 kV indirect contact discharge and 8 kV air discharge. The radiated RF immunity of the 1756-0BV8S memory board is as follows: At 10 MHZ 200 Hz 50% pulse at 100% AM 1890V/m, at 10 Hz 200% pulse at 50% AM 100V/m, at 900 MHZ 10V/m, A 1 KHZ sine wave ranges from 80 to 2000 MHZ at 80% AM, and a 1 KHZ linear wave ranges from 80 to 2.2 GHz at 1% AM.
