Telemetry module MT-221 allows wireless integration of measuring devices, PLC controllers, inputs/outputs systems, operator panels (equipped with a RS-232/485 communication port or Ethernet port) through 2G/LTE network. CODESYS combines advanced technical features with easy to use environment. Module can operate as local Master querying periodically an external device for user defined recourses. MT-221 creates mirror of the external resources in the memory and detects alarms, state changes and fulfilled logic conditions incorporating raw and calculated values. Received data can be locally analyzed based on user program. The module can work with master system directing data packets with queries or commands to its defined serial port or Ethernet port.

Module can be powered with two redundant direct voltage sources (11-30 V). In addition to communication and computing functions, MT-221 module allows you to record large amounts of data.

Industrial design, galvanic isolation, carefully adjusted technical parameters and easy to use configuration tools are important advantages, which makes MT-221 an optimal solution for demanding wireless telemetry, control, diagnostic and surveillance systems.
