The 1404-M405A-ENT was designed and produced by Allen Bradley, and it is a component of the Power Monitor 3000, which is part of the wider Power Monitoring and Management Products product line. Power monitor 3000 modules are intended to help both power users and power providers. It is comprised of a master module that aids in metering and native RS-485 connection, as well as a display module that displays settings, data, and instructions. It also has extra ports for connecting other devices if necessary. Aside from that, it displays various devices and applications for energy and power use control and monitoring. It is a microprocessor-based module for power monitoring and control. It is a microprocessor-based module for power monitoring and control. Load profiling, demand management, cost allocation, distribution system monitoring, emergency load shedding, and power system control are all possible applications. It is capable of replacing several classic transducers and meters. The master module has microprocessor-based operations and is responsible for power connection terminations. It also has control outputs, status inputs, an RS-485 communication port, and a display module. The display module is in charge of providing an economical and easy means of setting for the master module in order for it to run well. The display module has two (2) highly visible LEDs, as well as four (4) operator buttons. Buttons are used to browse through the menus of settings, data, and instructions. The LED Indicators on the 1404-M405A-ENT power monitor 3000 are six (6) bi-color LEDs. The three (3) LEDs on the left side of the 1404-M405A-ENT power monitor 3000 module provide information about the connectivity options, which include RS-485. The three (3) LEDs on the left side offer varying indicators depending on the communication option selected.
