MT-331 Telemetry module is a modern unit equipped with a quad band modem uBlox SARA-U201. MT-331 is keeping the aluminum housing and attractive price of the economical family and offers resources and possibilities that are available in advanced telemetry devices. Configurable modes of inputs/ outputs allow to prepare resources for the specific needs of the application. Except 2 dedicated binary inputs the user can configure additional 4 inputs (also as counter mode) and additional 2 binary inputs (instead of analogue). In control applications that require outputs the user can configure 4 channels. Measure functions can be realized by 2 configurable analogue inputs, mode 4-20mA or 0-10V. Built-in Li-ion battery keeps power on in case of loss of the main power supply. Supply output provides a stabilized voltage for external circuits and measurement sensors, also in energy saving mode.
MT-331 Telemetry module is a green line, energy efficient module compatible with renewable energy sources. Energy saving mode supported with internal built-in LI-ion battery allows to connect external batteries as main supply. Device can be also be supplied directly from solar panels. In energy saving mode the module “goes to sleep” (as in batteries family modules MT-7xx) and wakes up according to configured schedule or occurrence of some events.
Except standard SIM cards (Subscriber Identification Module) the MT-331 uses a built-in MIM card (Machine Identification Module) which is soldered in. Depending from preferences user can use:
a. Only MIM card, without SIM
b. Only SIM card, without MIM activation
c. SIM and MIM card (mobile network redundancy).
Module is equipped with flash memory reserved for capacity of 28,000 records data logger with maximal resolution of 1 sec. When actual value of register will be saved with 5 minutes period, the logger can store measured data of 96 days.
With MT-331 module we supply free of charge applications: MT-Manager and MTC for remote and local configuration, resources monitoring and firmware actualization, MT-Data Provider (OPC server, relation data base data saving engine) for communications environment for Microsoft Windows. These applications allow easy integration with popular SCADA systems,available on the market.
Similar to previous MT-30x family the MT-331 is equipped with stylish aluminum housing with DIN rail connectors. Though the MT-331 is derived from the economical inVentia modules series it has got 3 years warranty, like in professional series, and we are sure it will be useful in many professional applications.
