MB-LG-4 The Work Time Meter

The MB-LG-4 counter is a four-channel unidirectional work time counter with the implemented function of exchanging recorded data via an RS-485 port in accordance with the MODBUS RTU protocol. The MB-LG-4 module is a four-channel unidirectional counter. Each channel is independent and counts time based on individual settings. The result is presented as a floating-point number and, in parallel, as integer values divided into components in the form of days, hours, minutes, and seconds.
