SBR II AO | Smart Bob

The SmartBob AO with built-in 4-20 mA output and integrated keypad 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 takes a measurement, it automatically transmits an updated analog signal containing the measurement data to a PLC. The SmartBob AO can be programmed to initiate a measurement utilizing an internal timer to take readings at a predetermined time interval or an external start input can be used to take a measurement immediately, should one be needed. Two configurable relay outputs can be used to alert to measurement status or high, low, or error alarms.
