The JP 8Z is a distribution adaptor for the JM Series. The adaptor is utilised when home run wiring is desired. The JP 4MED master station and each JP 4HD sub master station will connect to this adaptor using CAT-5e/CAT-6 cable. The JP 8Z can surface mount using the mounting holes or with the W DIN11 mounting rail. One or two PS-2420 UL power supplies are used, depending on how many sub master stations are connected.
