ABB 6644424A1 Voltage Bus Monitor Assembly Enhanced COM Module and can communicate with SCADADescription: The 6644424A1 is a Voltage Bus Monitor Assembly manufactured by ABB. It is used with the Harmony Rack Power System (MPS3) to monitor the +5VDC, +15VDC, 15VDC, and MCOM voltages on the system bus bar. If any of these voltages are out of tolerance, the assembly will generate a low true signal, PF1. The input current of the assembly is less than 50mA. Key Features: Monitors +5VDC, +15VDC, 15VDC, and MCOM voltages on the system bus bar.
