For the switch valve feedback line, which is better: using two ZR-DJYVPR1x2x1.5 cables or one ZR-DJYVPR2x2x1.5 cable? At the site, the primary instruments are connected directly to the DCS; there are no junction boxes. How should the spare wires for the instruments be arranged?

Choose ZR-DJYVPR2x2x1.5; it saves both on terms of construction difficulty and cost. What is a spare cable used for? If all connections are made directly without using junction boxes, then there is no need for a spare cable

It doesn’t matter, right! But for backup, put the connector inside the repeater, the one you mentioned.
