1775-M58

Within the Allen Bradley PLC 3 series, the 1775-M58 functions as a vital memory module that ensures efficient data management in industrial control applications. This memory module supports a capacity of 32K words, making it suitable for various operational requirements. Users can easily monitor the module's function through three LED status indicators that display red and green colors to signal operational states.

Powering the module necessitates a supply voltage between 5 and 15 volts DC, which is obtained directly from the backplane. The backplane current is rated at 2.6 Amperes, making it important to consider during system design. This device is installed using a standard slot mount method, ensuring secure and straightforward integration into the system.

The 1775-M58 can adapt to a frequency input range of 47 to 63 Hertz. It is equipped with two types of battery backup: a lithium battery providing up to one year of backup power and a rechargeable nickel-cadmium battery that can sustain power for approximately 120 hours. This dual-battery feature enhances reliability, ensuring data is preserved even during power interruptions.

This memory module also accommodates expandable data tables, supporting both integer and status data, which is crucial for efficient data handling. The module operates effectively up to an altitude of 1,000 meters (3,300 feet) above sea level. Its programming interface utilizes ladder logic, and its operational temperature can range from 0°C to 60°C (32°F to 140°F), allowing for use in various environments.
