1. Designation of the module
The MT-703 (or MT-703 HC) module is a specialized telemetry device. It is optimised
for use in the simple measuring or alarm systems, which do not have network power
supply.
The module features compact design and low energy consumption from integrated
batteries. It is also capable of continuous counting of pulses on binary inputs, local
logging of measuring results and spontaneous transmission of information in case of
pre-defined alarm conditions. That’s why this device may be used in many applications
which require a periodical checking of parameters and a long term battery operation.
The module is manufactured in two versions which differ in capacity of internal battery
set (MT-703 model with standard battery and MT-703 HC model with doubled battery
capacity).
The typical range of applications of MT-703 module are water-sewage systems,
especially in measuring the water flow by means of water meters with potential-free
contacts as well as monitoring the water level in reservoirs and wells.
We suggest that you should study the operating description and configuration of the
MT-703 module as well as the examples of applications and instructions regarding
optimization of power consumption, given in the appendixes.
