Data acquisition and transmission device MIRT-881-WD3

Designation and application field

The data acquisition and transmission device is a product of the super functionality which is used for building of multi-functional automatic systems for commercial accounting of power consumption on its basis with distributed processing and storage of data.

The data acquisition and transmission device is a multi-functional controller of telemetry which performs collecting of telesignalling, telemetering data and command issue of telemetry.

The designation of the data acquisition and transmission device is metering of energy resources, time measurement, time synchronization in meters and collecting, accumulation and transmission of accumulated information to the highest level of information metering systems.

The module design of the data acquisition and transmission device in case WD3 lets set additional communication modules optionally (RF433, RF2400, Lora and so forth). An increasing of discrete inputs and outputs is possible because of installation of additional I/ O modules in the case of the data acquisition and transmission device.

Installation of additional communication modules and I/ O modules is possible without a disintegration of seals.
