The 1404-M805B-ENT-02 module is a master module for the PowerMonitor 3000 systems from Allen-Bradley. Master modules contain the microprocessor-based monitoring functions, status inputs, and control outputs, a port for the display module, and an integrated RS-485 interface. The 1404-M805B-ENT-02 module can be configured from the optional display module or from an external device. The RS-485 port can be used for communicating with Modbus RTU master moduless, PLC-5, SLC 500, or ControlLogix processors, and third-party devices. The 1404-M805B-ENT-02 module supports the 3-phase metering, setpoints, pulse input conversion, data logging, I/O, sag/swell detection, harmonics measurement, oscillography and the transducer/energy meter modes. The 1404-M805B-ENT-02 module supports 5 current inputs. The communication options available on the module is the Ethernet network. The revenue accuracy class of the 1404-M805B-ENT-02 drive is Class 0.2. The module comes with a 24 Volts DC power supply.

The operating temperature range for the 1404-M805B-ENT-02 module is from -40 to 140 degrees Fahrenheit. The storage temperature range is from -40 to 185 degrees Fahrenheit. The range for the relative humidity is from 5 to 95%. The operating vibration rating is 10 to 500 Hertz at 2 g. The operating and nonoperating shock rating is 30 g for 11 milliseconds duration. The control power range is 18 to 50 Volts DC with a maximum load of 15 VA. The accuracy of the voltage sense input is ±0.05%. The accuracy of the current sense inputs is ±0.05%. The accuracy of metering update rates is between 40 and 90 milliseconds. The accuracy of the frequency measurements is ±0.05 Hertz. The accuracy specifications are valid at 77 degrees Fahrenheit at a 50/60 Hertz unity power factor.
