MT-058 H v2 – battery-powered telemetry module

MT-058 H v2 is a modern battery-powered telemetry module designed for monitoring, logging and remote data transmission from dispersed infrastructure sites. The device has been designed primarily for use in locations where there is no access to a mains power supply or where connecting to the mains is difficult.

The built-in LTE Cat. M1 / NB-IoT modem ensures energy-efficient data transmission, enabling many years of autonomous operation. A standard set of alkaline batteries allows for operation for up to 5 years, whilst an optional lithium battery pack allows for up to 10 years, depending on the device configuration and operating conditions.

The module is equipped with 5 binary inputs, of which inputs I1–I2 can also function as high-speed counter inputs with a frequency of up to 250 Hz, and 1 analogue input (0–5 V DC) with a resolution of 12 bits. This enables it to interface with, amongst other things, water meters, flow meters, pressure sensors, alarm signals and other measuring devices.

In addition, the MT-058 H v2 features a 1-Wire port, compatible with the DS18B20 temperature sensor, and can optionally also work with a temperature and humidity sensor. An expansion board is also available, increasing the number of inputs by 4 binary inputs, 2 analogue inputs (0–5 V) and 2 PT1000 inputs.

The built-in data logger enables measurement results to be retained even during temporary loss of connectivity. The FLASH memory allows for the storage of up to 20,480 records, and the device can additionally store up to 2,048 MQTT records. Logging can take place at a time resolution of up to 1 second.

• Up to 10 years of autonomous operation – up to 5 years with a 4.5 V / 7.8 Ah alkaline battery pack or up to 10 years with an optional 3.6 V / 13 Ah lithium battery pack.
• Energy-efficient LTE-M / NB-IoT communication – designed for the reliable transmission of small data packets with minimal power consumption.
• MQTT with SSL encryption – secure integration with SCADA systems, IoT platforms and cloud solutions.
• 5 binary inputs, including 2 counter inputs up to 250 Hz – compatible with, amongst others, pulse counters, water meters and flow meters.
• 1 analogue input 0-5 V DC – 12-bit resolution and ±0.5% accuracy, enabling connection to, for example, pressure transducers.
• 1-Wire port – supports connection of an external DS18B20 temperature sensor.
• Optional temperature and humidity measurement – temperature range from −20 to +60°C and relative humidity from 0 to 100% RH.
• Expandable inputs/outputs – optionally 4 additional binary inputs, 2 analogue inputs (0–5 V) and 2 PT1000 inputs.
• Data logger – up to 20,480 records in FLASH memory and up to 2,048 MQTT records.
• Automatic alarm reporting – transmission of event messages without having to wait for a periodic connection.
• Programmable alarm thresholds, hysteresis and analogue signal filtering – facilitate local detection of abnormal conditions.
• IP68-rated enclosure – resistant to submersion to a depth of 2 m for 24 hours, suitable for demanding environmental conditions.
• Additional protection for the electronics – the device’s circuit board is coated with a layer that enhances resistance to moisture, dust and environmental factors.
• Remote configuration, updates and diagnostics, plus a USB-C port for local configuration.
• Optional MIM card mounted directly on the device’s circuit board, enhancing the solution’s reliability compared to a traditional removable SIM card.
• SMA connector enabling the use of an external GSM antenna.
• Support for external 7–24 V DC power supply, allowing the device to operate in installations using, for example, a battery and a solar panel.

MT-058 H v2 HeatSens – a solution for district heating

The MT-058 H v2 HeatSens variant has been designed for remote monitoring of district heating infrastructure and installations requiring temperature control. Support for temperature sensors via 1-Wire, the option to expand with PT1000 inputs, an analogue input for measurement transducers, and an optional adapter for reading data from heat meters allow the module to be used as a standalone component of a monitoring system for district heating nodes and networks.

Thanks to its battery operation, IP68-rated waterproof housing and LTE-M/NB-IoT communication, the device can also be installed in remote, damp locations or areas lacking the telecommunications and power infrastructure typical of conventional telemetry controllers.

Applications of the MT-058 H v2

• District heating and HVAC – remote monitoring of temperature, system parameters and alarm conditions, as well as integration with PT1000 sensors and heat meters.
• Water supply infrastructure – remote reading of water meters and flow meters, pressure monitoring, flood detection and control of dispersed sites.
• Remote meter reading – recording pulses from measuring devices and periodically transmitting the collected data to a master system.
• Monitoring of sites without a constant power supply – wells, chambers, pumping stations, telecommunications cabinets, industrial sites and environmental installations.
• Alarm and security systems – signalling of enclosure or cabinet opening, exceedance of limit values, flooding and other events requiring rapid notification.
