You could do $related = get_post_meta( $post->ID, 'relationship_field_name.id', true ); (no third argument, or set third argument to it's default of false if you need to get multiple items back)

or .ID if it's a post type or user, see more variations you may want to be cognisant of for the ID field's exact name or capitalization here: http://pods.io/docs/code/pods/find/#additional-information

Ohh, this is great thanks!
