Telemetry module MT-025 is a new proposition of the INVENTIA company in the segment of economic solutions. Thanks to its very attractive cost to feature ratio, the new construction is well suited for use in small sites remote monitoring and control systems. It allows monitoring, diagnosis and control of remote devices via text messages (SMS) or/and using data packet transmission over GSM provider network. As option we prepared MT-025 to operate with LTE 450 bands. It provides robust connectivity with increased coverage and deeper signal penetration.

Configurable text messages with a fixed or variable content (e.g. containing current measurement value) are convenient way to provide information to the monitoring center or directly to the defined staff phone numbers. Alarm messages can be generated on binary inputs and binary outputs state change, when measured analog values crosses alarm threshold, by timer and counter flags. Communication via GSM provider network enables secure and reliable communication with higher-order applications (SCADA, database, cloud based systems) allowing to expand the capabilities of the monitoring system using remote communication with difficult to access or distant sites.

MT-025 module has 4 optoisolated binary inputs, which can generate alarm messages to notify supervision.

The binary inputs can be configured as pulse inputs. The inputs can be used with S0-pulse interface (option). MT-025 module is also equipped with 2 configurable analogue inputs for measurement of current (4-20 mA) or voltage (0-10 V). The device allows also direct connection of temperature sensors using 1-wire interface (1 channel), configuring it in reading mode readings of a single thermometer or a bus supporting up to 4 temperature sensors. Additionally, the module has four relay outputs. Built-in data logger with capacity of 28 000 entries allows storing the measurements in the module memory.
