MT-121 Telemetry module is designed to perform various tasks of industrial, process and building automation. CODESYS combines advanced technical features with easy to use environment. Module is equipped with embedded data logger, protocol converter and wireless communication interface for packet transmission over 2G/4G networks. Dual-SIM technology ensures transmission reliability by access to 2 independent 2G/4G networks
Industrial design, galvanic isolation, carefully adjusted technical parameters and easy to use configuration tools are important advantages, which makes MT-121 an optimal solution for demanding wireless telemetry, control, diagnostic and surveillance systems. Module can be powered with two redundant direct voltage sources (11-30 V). Analog output allows smooth control of an external device. Ethernet port allows connection with extensive network of peripheral devices supporting Modbus TCP.
