Hi every one

I am going to use 7PA30 as TCS for a long trip circuit (nearly 2 km). becuase of exeptional scheme of the trip circuit, the main coil of 7PA27 (Trip relay) is included in the trip circuit to be supervised.

now i am :

1- how big is the current injected by 7PA30?

2- can this current cause the coil of 7PA27 to be energized?

I have read the manual for 7PA27 and it is writen that the pickup voltage is 69-77 volt (for supply voltage 110VDC). but i can not calculate the voltage that will be used on the coil beacause I couldn't find amount of current injected by 7PA30 in it's manual.

thanks in advance for your kind solution
