1403-MM05A

The 1403-MM05A, belonging to the Allen Bradley Powermonitor II series, operates as a sophisticated master module for monitoring electrical parameters. It supports up to five current inputs, where the nominal full-scale input current spans from 0 to 5 amperes. The unit is engineered to handle continuous currents with an overload profile of 15 amps without sustaining damage. For brief periods, it can withstand up to 300 amps for one second, emphasizing its robustness under load.

The current input burden is relatively low at 0.05 volt-amperes, highlighting its efficiency in current monitoring. Voltage input ratings are extensive, accommodating line-to-neutral values between 120 volts and 347 volts, with the line-to-line ratings compatible from 208 volts to 600 volts, adding considerable flexibility for integration.

For power supply, the module requires a control voltage between 120-240 volts AC at 50 or 60 Hz, or a DC input of 125-250 volts, ensuring operational adaptability across various power systems. The analog input nominal rating is set from 0 to 1 volts, applicable for both AC and DC signals, allowing further analysis and control capabilities.

The relay contact ratings signify the module's capacity. It supports resistive loads rated at 10 amps for both 250 volts AC and 30 volts DC, along with a maximum of 0.25 amps at 250 volts DC. The inductive relay contact rating stands at 240 volts AC, with a make capacity of 3600 volt-amperes and a break capacity of 360 volt-amperes, showcasing its suitability for multiple operational demands.
