Description

Digital panel meters EX with and w/o illumination. The modules of the EX series were specially designed for build-in situations of housings and panels. Simple mounting and no need of galvanic separated support-voltage, those meters with high voltage and current precision are the real alternative for analog meters. They are useful in all areas where it is necessary to deliver reliable physical Data to operator. Measure and test engineering, solar technique and electronics, as well as machine- and apparatus engineering are typical area of application.

Functions

The modules of the EX-Series offer following functions:

Measure

digital snap-in instrument oft he EX-series are designed to measure directly electrical and non-electrical physical metrics.

Reading

Digital-Instruments are used to avoid parallax error of analog instruments, to have a far higher resolution and ability to view the values from further distances.

Initial Operation

Please check the wiring before switching ON.

Maintenance, proper disposal

Please consider as well following advices:

 For cleaning do not use carbon containing cleaners, nor benzine, alcohol or similar.



Damages caused by disregard of advices from instruction manual lapses warranty

claims.

Specifications

Auxiliary Voltage

The instruments do not need galvanic separated auxiliary voltage (common ground). (does not apply for EX2030 to EX2034!)

Polarity

The instruments display polarity automatically

Decimal point

The position of the decimal point can be adjusted by option..

Exceedance of range

Exeedance of range are displayed by a single 1 or -1 (Overflow display).

Lightning

The modules of the series EX30xx have an built-in green-yellow LED-light(12V).

Mounting

Snap-In mounting for fixing and simple finish for housings and panels.

Housing color

The housing color is black.

EX-Voltage Modules (Voltmeters)

Modules of the EX Series were specially designed for use in front panels and housings. Due to ease of mounting and no need of a galvanic separated auxiliary voltage, these exceedingly precise meters are a true alternative to conventional analog meters. Thus they are very useful in all applications where it is important to obtain reliable physical data to users.

Specialities (sample schematic)

Current measuring with voltmeters (only with EX2068 / EX3068)

Basically current measure is as well possible with voltage meter modules. For such, a so called „shunt-resistor“ is necessary. This option is already integrated in the current meter modules. To use Voltmeter modules use below schematic to avoid damage tot he modules. Important: The Measure-resistor (Shunt) has to be connected in the ground wire of the load!

Voltage measuring (only with EX2068 / EX3068)

Measuring with separated ground wire! The voltage drop in the measure wire can be up to 300µV, depending the length. This is resulting in a displacement of the zeropoint. With below schematic this effect can be avoided.

EX-Current Modules (Currentmeters)

Modules of the EX Series were specially designed for use in front panels and housings. Due to ease of mounting and no need of a galvanic separated auxiliary voltage, these exceedingly precise meters are a true alternative to conventional analog meters. Thus they are very useful in all applications where it is important to obtain reliable physical data to users.

Connection Sample

(Supply Voltage has to be separated from Measure Voltage)

The modules EX2077 and EX3077 are not equipped with an integrated Shunt. Thus is valid the same schematic as for „Current Measuring with external shunt“ (Specialities page 7).

EX20xx, EX30xx

Adaption and Adjustment

Vehicle and Vessel Installation

The maximum input voltage of the modules is up to 30V. Whereas in vehicles with 12V on-board voltage occasionally higher voltages appear (mostly short term), but may result in damage of the module. The use of a so called VDR (voltage depending resistor) parallel to the supply voltage at the module will avoid damage. Those components are available at standard electronic distributors, sample type: EPCOS Type S05K17.

The EX30xx from production >01/2015 already include a overvoltage and reverse voltage protection circuit !

Supply Voltage for the Illumination of the 30xx

The illumination supply voltage of the modules EX 30xx is designed for 12V; the current consumption is about 7mA. Shall the modules be used with other supply voltage (i.e. 24V), a series-resistor need to be applied. Rv = Uv / Ib with Uv = (applied supply voltage - 12V) and Ib = current consumption illumination = 7mA, thus at a supply voltage of 24V the series-resistor shall be 1,7kOhm. Whereas the used value can be between 1 und 2 kOhm, depending the desired brightness).
