Analog output to Analog input wiring

Dear everyone,

I've come up to a problem i need your help with.

On the job we need to transfer an analog output signal from another plc to our remote io station, a network connection is not possible.

My question is how do i connect the 2 wire 4-20mA output signal to my siemens  6ES7134-6HD01-0BA1 input card?

is this possible or do i need an isolating amplifier?

Thanks for your help!
