Product description: Tinycontrol tMPC-04 - 4-channel Modbus RTU pulse counter
The tMPC-04 is a compact module enabling the integration of pulse meters with automation and monitoring systems based on the Modbus RTU protocol. Four independent pulse inputs allow for simultaneous monitoring of multiple meters, and measurement results are provided as pulse count, calculated consumption, and estimated power. The default configuration allows for immediate start-up without additional settings , while advanced parameters can be conveniently configured via the USB port. The module works with Tinycontrol LK3.5+ and LK4 controllers and other devices supporting Modbus RTU communication via the RS485 bus .
