The SmartBob II Remote Display unit (RDU) communicates with a SmartBob II remote and the master PC via the RS485 network. The units can be attached at any position along the network. The RDU is a listening device that provides two major features to the SmartBob system, a 4 to 20mA current loop output and a remote display or readout of measurements. The current loop output can be used as an interface to share measurement information with a PLC, DCS, or any other device that reads a 4 to 20 mA signal. The LCD display provides readout of distance to product, height of product, and percent of product in the storage vessel.
