The IDM, hereinafter the device, is part of the MVV device and is intended for dynamic display of scaled values ​​of measured current parameters on single-line digital LED indicators and the percentage value of one of the parameters of the analog LED scale.
They are installed on the outer wall of cells of power plants and substations.
The source of information for devices can be a digital measuring converter (MVV), which supports the RS-485 physical interface and the Modbus exchange protocol (RTU) in slave mode.The IC is used in conjunction with a measuring transducer type. MVV that collects current parameters from MTE 11XX, MTE 12XX.
The exchange rate is 9.6 kbaud.
Configuration for specific display conditions is carried out using mechanical keys installed on the front side of the device display.
With the help of one of the buttons, you can perform a TEST of the device.
The information channel is organized on the RS-485 physical interface with galvanic isolation from the main electronic nodes of the device.
All external connections are made with clamps installed on the device body.
The overall dimensions are:
IDM — 95x70x30 mm. Weight no more than 50 g

IDM mechanical protection level 20
The device is powered directly from the MVV device or from an external DC power supply with a voltage of 5 V and a network frequency (50±3 Hz). The power consumed by the IDM is no more than 1 W.
Operating conditions:
— Ambient air temperature from -20 to +50 ºС;
— Ambient air humidity from 40 to 80% at +25 ºС, without moisture condensation;
— Atmospheric pressure from 84 to 107 kPa.
— the level of influence of constant and (or) alternating magnetic fields of the mains frequency at the place of installation of devices does not exceed 400 A/m.
