The KB-1 keyboard is designed for calibration, adjusting settings, and switching modes for Mxx, Dxx sensors, and other devices produced by Emag-Serwis Sp. z o.o. It prevents unauthorized personnel from making changes to sensor settings. The keyboard features four functional buttons and a CONSERWIS-type connector used to connect to the controlled device. The integrated microcontroller allows the device to recognize the keyboard, enabling calibration data and other necessary information to be input. The keyboard also has LED indicators to show the mode of operation, calibration stages, or other device-specific states. The keyboard is powered by the device it is connected to.

The explosion-proof mini-control unit MCCD-01 is a measurement and control device designed for use in mining systems for monitoring safety and technological parameters. A typical application of the mini-control unit is in the SMP-NT environmental parameter monitoring system in a mine. The MCCD-01 serves as an interface between analog and binary sensors and the surface part of the system. It ensures continuous reading and processing of analog and binary signals, converts them into digital signals, transmits the processed data to the surface part of the system, and receives configuration and control data from the surface part. It can also be equipped with control outputs for binary control of external devices and electrical circuits. In this case, based on the configuration data received from the surface part and the status of the analog and binary inputs, the mini-control unit can generate control signals according to predefined algorithms.

The MZT 10/60M is designed for power supply and data exchange with sensors located in the underground part of a mine. It has ten linear power supplies, each capable of powering up to four underground sensors (depending on the type). The MZT 10/60M continuously monitors the power currents, voltages, and resistances of the individual lines. To ensure uninterrupted power supply, it is equipped with two independent network power supplies. It can also be powered from a DC source with a nominal voltage of 48V. Two galvanically isolated Ethernet interfaces allow the creation of a redundant network connecting the MZT module to the supervisory system computers. The MZT 10/60M module is designed for mounting in a standard 19″ rack.
