Can I use the digital and relay outputs of PM5000 for low level switching input? Can I use the digital outputs to control electromechanical relays which have high inrush current when closing?

Dear all,

Is there any IEC or other standards for the electrical function of power meters?

Now I want to use the digital and relay outputs of PM5000 for PLC input application, generally the PLC inputs need low level switching input, and the rated current is lower than 10mA, but there is no parameters clarifying the Minimum load of the outputs in the technical documents of PM5000 and other meters, so is there any reference?

The load capacity of PM5000's digital outputs is low ( 20mA and 125mA),we know there will be a high inrush current when energizing AC electromechanical relays and contactors,  so can I use these outputs to control electromechanical relays and contactors? Will it be safe for the controlling and the meter's outputs?

Thanks!
