Active inputs 

(no external power supply required) 

Technical data (

acc. EN62053-31, class B) 

Open circuit voltage 

≤ 15 V 

Short circuit current  

< 15 mA 

Current at R

ON

Example with meter pulse and status inputs 

 

5.8  Digital outputs  

The device has two standard digital outputs for which an external 12 / 24 VDC power supply is required.  

 

The power supply shall not exceed 30V DC! 

Usage as digital output 

► Alarm output  
► State reporting 
► Pulse output to an external counter (acc. EN62053-31) 
► Remote controlled output 

PQ3000 

PQ5000 

 

 

 

 

 

1)

 

Recommended if input impedance of counter > 100 kΩ

 

 

Driving a counter mechanism 

The width of the energy pulses can be selected within a range of 30 up to 250ms, but have to be adapted 
to the external counter mechanism.   

Electro mechanical meters

 typically need a pulse width of 50...100ms. 

Electronic meters

 are partly capable to detect pulses in the kHz range. There are two types: NPN (active 

negative edge) and PNP (active positive edge). For this device a PNP is required. The pulse width has to 
be 

≥ 30ms (acc. EN62053-31). The delay between two pulses has to be at least the pulse width. The 

smaller the pulse width, the higher the sensitivity to disturbances.
