HUB-SDM8 1. Introduction The HUB-SDM8 is an 8-channel hub for SDM peripherals and power connectors, and is used to daisy-chain multiple sets of SDM (Synchronous Device for Measurement) devices to a single Campbell Scientific, Inc. datalogger, as well as run multiple power connectors using a 16 AWG wire. The HUB-SDM8 is comprised of an environmental enclosure with eight compression fittings (two larger for 16 AWG power wires) and eight terminal strips.
HUB-SDM8 4. Installation and Wiring A U-bolt is used to mount the HUB-SDM8 to a 1.25 inch NPT pipe. The spring-loaded guillotines are opened with a small flat blade (2.5 x 50 mm) screwdriver (p/n 8125). Orient the screwdriver blade so that the blade edge is perpendicular to the orange separators. Gently insert the small flat blade screwdriver into the square slot located next to the circular wire port until it bottoms out.

HUB-SDM5 The HUB-SDM8 can provide the same function as the HUB-SDM5, which is a 5-channel hub for SDM peripherals. Use the supplied plugs to seal the unused bulkhead fittings to use the HUB-SDM8 to connect multiple SDM devices to a single Campbell Scientific, Inc. datalogger.
HUB-SDM8 7. Maintenance There are no user-serviceable parts in the HUB-SDM8. Make sure that all unused bulkhead fittings are sealed with a plug and that the lid is tightly fastened.
