SmartBob AO with 4-20 mA Output to a PLC The SmartBob AO level sensor analog output for use by facilities that prefer an analog output to measurement data. A simple push- button user interface built into the SmartBob AO circuitry is used to configure the settings for each SmartBob AO. Once setup is complete, measurement data is sent directly to a PLC, with all settings for the bin saved in the non volatile memory of the Continuous Bin Level Monitoring The SmartBob AO with built-in 4-20 mA output can easily replace any 4-20 device by simply installing the SmartBob on the top of the bin and wiring the sensor to the existing 4-20 input. When the SmartBob AO measurement data is sent directly to a PLC, it eliminates the need for a C-100 or RSU control console or eBob software, as the programming interface and controls are built in to the SmartBob AO circuit board. There is one analog output per SmartBob, with this one-to-one relationship requiring a dedicated connection from each individual • Simple user interface to • Measures bins timed intervals with four different • Initiate measurements external start input current loop Each SmartBob AO requires a dedicated connection to the PLC.

Simple Setup & Configuration The SmartBob AO level sensor requires standard 115 VAC or 230 VAC power. There are two current source options for supplying power. The recommended option is to use an isolated 4-20 mA current loop which uses the PLC to provide power. Alternatively, a non-isolated 4-20 mA current loop can utilize the SmartBob sensor to provide power for the loop.
