EX20xx, EX30xx Safety Information Please observe the following when using the product: This Panelmeter left our factory in perfect technical condition. To preserve this state and ensure safe operation, the user must observe the safety instructions and warnings. Electronic components and accessories do not belong into child hands.
EX20xx, EX30xx 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.

EX20xx, EX30xx 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.
EX20xx, EX30xx 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! Measure Range 0..19,99 mA 0..199,9 mA 0..
EX20xx, EX30xx Sample schematics For EX2072, EX2073, EX2074, EX2075, EX2076 and EX3072, EX3073, EX3074, EX3075, EX3076: For EX2030, EX2031, EX2032, EX2033, EX2034: 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). Copyright BECKMANN+EGLE GmbH, All Rights Reserved. Page 8 Internet: www.bue.
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.
