Flexible Cable
This cable connects two boards: Communication and Extension Board
3.2 Extension board
The Extension Board contains a set of various I/O interfaces (digital inputs, analog inputs, serial interfaces). Also, this
board can contain a power supply from an external source and a power manager. The power manager allows the device
to automatically switch power to the internal battery when the external power is lost. The main elements of the
communication board are shown in the Figure 2.

Description
Discrete Inputs
The block of discrete inputs consists of 4xDI, which can be configured in two modes: DRY or Open
Drain. The settings are made individually for each input. Depending on the Application, these inputs
can be a pulse counter or a binary input or other.
Line Supervision inputs
These inputs are used for line monitoring (normal / short circuit / open line) or other functions such
as a leaks detector. The functionality of these inputs is determined by the Application.
Analog Inputs
The device contains 4 analog inputs: 2x0-20mA and 2x0-10V
