Operating time counter with Modbus RTU output, 4-channel, 1 module MAX-MB-LG-4LO

Precise working time measurement with the possibility of integration with automation systems

The MAX-MB-LG-4LO working time counter is a reliable device designed for precise measurement of the working time of machines and equipment. The four-channel design allows monitoring the working time of several independent elements in one module, which is particularly useful in production plants, workshops or HVAC systems. MODBUS RTU communication enables easy integration with SCADA, PLC and other automation devices, providing remote data reading and process control.

Versatile application and easy installation

The device mounted on a DIN rail takes up only 1 module, which saves valuable space in the control cabinet. A wide range of input voltage (9…30 V DC) ensures compatibility with various power sources. The counter is ideal for both professional installers and end-users looking for a reliable solution for monitoring working time.

Functionality and reliability in every detail

• Four independent channels: Allow simultaneous measurement of the working time of four different devices or processes.
• MODBUS RTU communication: Provides easy integration with automation systems and remote data reading. Results are presented in FLOAT (hours) and INT (seconds, minutes, days) format, which facilitates data analysis.
• Reset input: Allows manual or automatic resetting of the counter to start a new measurement.
• Time filter: Eliminates interference at the counter input, ensuring measurement accuracy even in harsh industrial conditions. Short pulses are ignored, preventing false readings.
• Power failure memory: Ensures data retention even in the event of a temporary power loss.
• Configurable counting input: Possibility to choose input activation with high or low voltage signal and circuit closing or opening.
• High accuracy and reliability: Ensured by a solid construction and high-quality components.
• Wide counting range: Up to 1314000 hours – sufficient even for the most demanding applications.

The MAX-MB-LG-4LO counter is an excellent choice for anyone who needs a precise and reliable tool for monitoring the working time of machines and equipment and integrating with industrial automation systems. IP20 protection class ensures safe use in an industrial environment.
