Module MSP-2.1 is an Ex-component, and is designed to be built into wearable mining devices (e.g. lamps) and work as part of the system of zonal positioning of miners and transport SPGT-41.
Structurally, the modules consist of an electronic board covered with a heat-shrinkable tube with an adhesive sublayer covering all components and printed conductors. For connection of external intrinsically safe circuits in the module MSP-2.1 four wires (power supply circuit, control circuit and control circuit of third-party devices) are taken out.
