The WeightechUSA WTX-12D (SKU 40063) connects up to 12 digital load cells simultaneously, with an unlimited number of extra junction boxes on the same circuit. A 12 V, 15 W power supply built into the box powers the digital cells. The box is made entirely of stainless steel with special sealing and rated IP67.
The datasheet does not list applications. As a general-purpose digital multi-cell junction box it is typically used on:
Collects many digital load cells from long platforms on one circuit.
Individual power jumpers per channel help with bus-scan addressing.
Multi-cell vessel weighing, indoors or outdoors.
Stainless-steel, IP67 enclosure with a GORE valve against condensation.
Power supply integrated in the box powers the digital load cells, for greater reliability.
Each channel has its own power jumper, which makes addressing via bus scan easier.
Equalizes pressure inside the box without letting water or oil in, preventing internal condensation and extending service life.
Stainless-steel PG69 cable glands: stronger and safer connections. Also protection against electric shock and very good thermal stability.
