The SDI-12 Terminal Bus Kit (pn 33815) makes it easier for you to connect wires from multiple SDI-12 sensors into one set of terminals on a data logger. The 33815 uses six DIN-rail mountable (pn 27479) 6-wire terminal blocks. The 33815 jumpers two connectors together at a time (pn 32918). This setup allows up to 11 SDI-12 sensors to be connected to one set of terminals on a data logger.
