Why Choose the ABB M4M 20 PROFIBUS Network Analyser?
The ABB M4M 20 PROFIBUS is a versatile three-phase network analyser and panel-mounted power meter designed for accurate electrical measurement, energy monitoring and basic power-quality analysis in industrial and commercial installations. As part of the advanced ABB M4M 20 network analyser series, it combines comprehensive electrical measurements with PROFIBUS communication for integration into automation and energy-management systems.
The M4M 20 PROFIBUS provides PROFIBUS DP-V0 and Bluetooth communication, allowing electrical data to be incorporated into industrial control and monitoring architectures while supporting convenient local commissioning. Its colour graphical display provides clear visualisation of measured parameters, while two digital outputs add flexibility for signalling and energy-management applications.
With a wide 48–240 V AC/DC auxiliary supply, support for 1 A and 5 A current-transformer secondary circuits and a compact 96 × 96 mm front-panel format, the M4M 20 PROFIBUS is well suited to switchboards, distribution panels and industrial control systems. ABB order code 2CSG251131R4051 identifies this PROFIBUS-enabled M4M 20 variant.

Connected Electrical Monitoring for Industrial Systems
Network analysers such as the ABB M4M 20 PROFIBUS provide detailed visibility of electrical distribution systems by measuring key electrical and energy parameters. Monitoring voltage, current, power, frequency, power factor and harmonic distortion helps operators assess system performance, investigate abnormal conditions and identify opportunities to improve energy efficiency.
PROFIBUS DP-V0 connectivity makes this M4M 20 model particularly suitable for industrial environments where electrical measurements need to be integrated with PLCs, supervisory control systems and established PROFIBUS networks. Bluetooth connectivity complements the wired industrial interface by supporting convenient local commissioning and interaction with the analyser.
