【英文介绍】

The expanded memory module, known as the 1756-M2 memory module, is used in a variety of applications in harsh industrial environments. The device is part of the ControlLogix 1756 product family from Allen-Bradley/Rockwell Automation. ControlLogix systems can be constructed from a variety of high-performance components, such as processors, controllers, memory boards, and different analog and digital modules. The ControlLogix modules are installed in the case, and they communicate via ControlNet and EtherNet/IP networks. The available ControlLogix controller has a data and logic memory capacity of 750 KB to 32 MB and a backplane current of 1.20 to 1.25 amps at 5.1 V DC.

The 1756-M2 extended memory module comes with 1 MB memory capacity and an open housing. According to the specifications provided by Allen-Bradley, the device operates in a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and has a storage temperature of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). In addition to this, the 1756-M2 module has moderate vibration (2 G at 10 to 500 Hz frequencies) and shock (30 G) tolerance, and can operate in environments with a relative humidity rating of up to 95% (non-condensing). The 1756-M2 module supports emission class A (Group 1) with temperature code class T4A/T4. The device is designed to meet the requirements specified by standards such as UL, CE, CSA and C-Tick standards. According to IEC 61000-4-3, the ESD immunity of 1756-M2 devices is 6 kV (indirect contact discharge) and 8 kV (air discharge).
