The smart-MAIC D105-10 is a universal DIN-rail pulse analyser that collects pulses from water, gas, heat and other meters together with sensor readings and sends them to the cloud over Wi-Fi. The Wi-Fi antenna is built into the housing, so no extra antennas or cables are needed.

Inputs, connectivity and integration

• Pulse inputs (2) – For water, gas, heat, fuel or electricity meters with a pulse output, e.g. a dry contact or the NO5W magnetic sensor. The pulse value of the meter is set in the cloud.
• 1-Wire input – Up to 5 DS18b20 temperature sensors on one line OR one DHT22 / D280 (temperature, humidity, pressure). Sensors connect directly to the D105 terminals.
• Analogue input 0.1–18 V DC – For pressure (G1/4), level (mH2O), light, pH, TDS and other sensors with a voltage output. Sensors powered from 12–24 V DC need a separate power supply, and their output must not exceed 18 V.
• RS485 (input / output mode) – For Modbus sensors CO2-5000, T4W, T5W, 4in1, D105 Solar or other equipment, e.g. reading inverter data. In the Extended version the D105 can act as a Modbus Server and provide data to a SCADA system or controller.
• Wi-Fi with built-in antenna – 2.4 GHz Wi-Fi through an antenna inside the housing – no external parts. Suits a plastic enclosure or a room with a stable signal.
• Cloud, MQTT, API – Data goes to the free smart-MAIC cloud and via MQTT and API (Standard – every 60 s, Extended – every 5 s). Where there is no Wi-Fi, use the 4G LTE Wi-Fi USB modem.
• Relay (< 50 W) – For remote control of equipment: a small load directly or a contactor coil.

• 2 pulse inputs – water, gas, heat or fuel metering without manual readings
• 1-Wire input – up to 5 temperature points or temperature and humidity from one sensor
• Analogue input 0.1–18 V DC – pressure, level, light, pH, TDS and other voltage signals
• RS485 – Modbus sensors (CO2, wind, soil, solar radiation) or other equipment
• Relay < 50 W – remote control of equipment
• Built-in Wi-Fi antenna – no external parts, a tidy installation in the enclosure
• Cloud, MQTT, API – charts, reports and integration with other systems

• D105-12 – The same analyser, but with an external Wi-Fi antenna and the option of a 3 m remote antenna – for metal cabinets and weak-signal locations.
• D103 energy analysers – Measure electrical parameters (voltage, current, power, energy); the D105 counts pulses and sensor values – for water, gas, heat and environment.
• PQ-4G – An industrial Modbus → 4G module with RJ45 – only a data link. The D105-10 collects data itself and sends it over Wi-Fi.

• Remote reading of water and gas meters in houses and flats
• Rental properties – splitting utility costs between tenants
• Boiler rooms and heat substations – temperature and pressure monitoring
• Server rooms and warehouses – temperature and humidity control
• Greenhouses and farms – air and soil parameters
• Water tanks and boreholes – level and pressure monitoring
• Plastic enclosures and rooms with a strong Wi-Fi signal

• Installation and 230 V connection must be done by a qualified electrician with the power off
• Do not exceed 18 V DC on the analogue input
• Use a separate power supply for sensors rated 12–24 V DC (not included)
• Keep the relay load below 50 W; switch higher power through a contactor
• A metal cabinet attenuates Wi-Fi – check the signal inside the cabinet with the door closed before installation
• Do not run signal wires together with power cables

Quick selection guide

smart-MAIC D105-10 – pulse analyser with built-in Wi-Fi antenna

The D105-10 collects pulses from water, gas and heat meters plus sensor data and sends them to the cloud through its built-in Wi-Fi antenna. Choose it for plastic enclosures and locations with a stable Wi-Fi signal.
