Modular multifunctional meter, TrueRMS, RS485 SM101C

Multifunctional meter for DIN rail mounting

This is an advanced, modular multifunctional meter designed for precise measurement and monitoring of electrical parameters in installations. The device offers a wide range of functions, from measuring voltage and current, through active and reactive power, to frequency. RS485 communication enables integration with automation systems and remote data reading.

Versatile application and measurement accuracy

The SM101C meter is a reliable tool for both professional installers and end-users who need detailed information about energy consumption and the condition of the electrical installation. Thanks to its high accuracy class (0.5S for active energy), it provides reliable measurement results, which is crucial in billing systems and energy efficiency analysis.

Functionality and communication

The device has 7 analog inputs and 1 digital input, allowing connection of additional sensors and expansion of the system's functionality. Support for the Modbus protocol ensures easy integration with existing building management systems (BMS) or industrial SCADA systems. Compact dimensions (73 x 67 x 90 mm) allow mounting in standard distribution boards on a DIN rail. The IP20 protection class provides protection against accidental contact.
