【英文介绍】

The 1756-M3 module is an extended memory module designed and produced by Allen-Bradley/Rockwell Automation. As can be seen from the product code itself, the module is part of the Bulletin 1756 product line for the ControlLogix system. The ControlLogix environment includes processors, amplifiers, controllers, digital/analog I/O modules, communication modules, and memory modules. The 1756 ControlLogix product family offers electronic keying, enhanced safety features, point-level output of fault states, optimized communication, real-time channel sampling, and isolated and non-isolated module types. The 1756-M3 memory module is used with controllers with memory capacities ranging from 750 KB to 32 MB. The backplane current of these controllers ranges from 1.20 to 1.25 amps at 5.1 volts DC and from 0.014 amps to 14 mA at 24 volts DC.

The 1756-M3 memory module is suitable for the following operating conditions: operating temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and storage temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). In non-condensing conditions, the relative humidity level should be between 5% and 95%. The IEC temperature code for this device is T4A/T4 and the device belongs to the Class A/ Group 1 emission group. The 1756-M3 memory module can withstand 2 G of vibration and 30 G of shock at 10 to 500 Hz. The device weighs about 0.22 kg (7.7 oz) and is mounted in the case like other components of this type. The module includes 6 kV indirect contact discharge ESD immunity and 8 kV air discharge immunity, according to IEC 61000-4-2 standards.
