The new telemetry controller MOBICON MT-156 HM

Inventia.online > News > The new telemetry controller MOBICON MT-156 HM

The new model MT-156 HMI is a telemetry controller for multichannel temperature measurement designated for heating, refrigeration, air conditioning systems, boiler rooms, server rooms and other facilities that require monitoring of many PT1000 temperature sensors. The module allows connection of up to 10 PT1000 sensors and is equipped with a graphical OLED display, M-BUS port, Ethernet port and serial ports enabling, among others, communication with wireless, battery-powered temperature and humidity LoRa sensors.

The MT-156 HMI controller comes standard with a modern 3G modem. Dual-SIM technology provides access to two independent GSM networks, providing redundancy of transmission infrastructure. Rich and diverse I/O resources, along with available serial interfaces and an Ethernet port, ensure the free integration of external devices, sensors and access to the controller from external systems, using the Modbus RTU and Modbus TCP protocols. Detachable terminal blocks, divided into segments, facilitate installation and service works. Ten PT1000 inputs give the possibility of direct connection of standard resistive sensors, ensuring simultaneous temperature measurement at many points. An additional RS-232 serial interface with 5 VDC / 500 mA DC power supply enables connecting a LoRa radio sensor hub (model IOT-RG-01) or any device in the RS-232 standard requiring a supply voltage in the range from 0 to 5 VDC. The MT-156 HMI model is also equipped with an M-BUS port. Data exchange with external energy meters or heat counters does not require an external converter. The high performance of the bus allows you to connect up to 16 M-BUS slave devices.

The MT-156 HMI unit, like other MOBICON series telemetry controllers, provides functionality typical for programmable logic controllers (PLC), i.e. support for a local user program (control algorithms, data processing, calculations). The user program code can be written in one of three available editors: text, MTprog conditions sheet and ladder diagram, which are supplied with the free MT Manager utility software. The dozens of logic and arithmetic functions available in the program editor are supplemented with the ability to define up to four PID controllers with the valve control option. The user program and telemetric module configuration parameters are stored in the internal flash memory. It is important for some industrial applications that it is possible to secure the controller’s configuration and program with a password and to provide a lock before reading them to protect intellectual property.

In addition to the measurements and control functions, MT-156 HMI enables data logging by collecting data records according to a defined configuration in the non-volatile internal memory of the controller. Measurement data can be additionally stored on an external SD memory card. The memory card can also be used to create a backup copy of the module’s configuration as well as to locally update the firmware.

MT-156 HMI is equipped with a graphic OLED display. Using a convenient display menu, the user can easily present text, any register, or marker from the internal memory of the controller, a configured graph or diagram. Using the dedicated menu, in addition to changes in the values of outputs and internal registers of the controller, you can also change the name of the module giving the unique identifier of the object. Service screens were also designed so that the user can enter basic configuration parameters without a computer connection, i.e. the PIN number for the SIM card, or select the GSM operator’s network type (2G/3G).

The function of restoring factory settings of the device is also available from the menu screen.

The MT-156 HMI telemetry controller, like the other units of the professional MOBICON family, is covered by a 3-year manufacturer’s warranty.
