Important product changes in hardware version 2 of MT-151 LED Telemetry Module (MT-151 LED V2)

MT-151 LED V2 is a family of new generation telemetry controller for demanding tasks and applications. MT-151 LED V2 model is a professional, industrial design combining functionality of programmable logic controller, data logger, protocol converter and wireless communication interface for GPRS packet transmission over GSM network. Dual-SIM technology ensures superior level of GSM network availability, with redundant channel of data transmission. Ethernet port provides powerful capabilities of integration with other devices and systems of the user.

48 diagnostic LEDs annunciate clearly detailed information about actual status and operation of the module. With compact, robust design, integral GSM modem, attractive technical features and easy to use configuration tools the MT-151 LED V2 controller is an optimal solution for demanding wireless telemetry, control, diagnostic, surveillance and alarm systems.
