About 1756-L55
The 1756-L55 module is a processor module commonly used in ControlLogix industrial environments. This processor module is designed and produced by Allen Bradley/Rockwell Automation and is considered a high-quality and top performing component. The ControlLogix 1756 series offers various models of controllers and memory boards manufactured according to industry standards and regulations in North America and Europe. This means that the 1756-L55 processor module meets the requirements of different IEC 60068 ratings in terms of temperature, humidity, vibration, and impact resistance.
The 1756-L55 processor module does not have any user memory, but it contains a 1756-BA1 battery. The backplane current of this module is 1.23 to 1.25 amperes at 5.1 volts DC, and 0.014 amperes at 24 volts DC. This device has an isolation voltage of 30 volts (continuous) and a basic insulation type with RS-232 communication ports. In addition, it should be mentioned that this type of module has been tested to withstand a voltage of 707 volts DC for a duration of 60 seconds. The power consumption of the 1756-L55 module is 5.6 to 5.7 watts, and the heat dissipation per hour is 19.1 to 19.4 BTU. The shell of the device is open and its operating temperature range is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). The storage temperature range is -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The 1756-L55 module weighs approximately 0.35 kilograms or 12.5 ounces. In addition, the product has a T4 IEC temperature code and uses 1756-CP3 or 1747-CP3 serial cables.
