TINYCONTROL tMPC-04 - Pulse counter with Modbus interface LK3 & LK4

The tMPC-04 is a 4-input pulse counter designed for use with any meters with pulse outputs. It communicates via Modbus RTU to provide pulse counts, calculated energy and estimated power. Other measures can also be measured, e.g. flows from water or gas meters. Conversion to these units is based on user-entered coefficients (e.g. pulses per kWh), the default is 1000 pulses per unit.

Default setup

• Modbus Slave ID: 1
• Pulse Conversion Factor: 1000 pulses per unit (e.g., imp/kWh) for all 4 inputs

If these settings match your energy meters, the device is ready for immediate use.
