Model 3005 Analog Board for the Siemens Digital Level Sensor Providing for single analog output The Model 3005 is designed to provide a single analog output from Siemens digital level sensors (DLS). It provides a 4-20mA signal output for the total fluid level of the tank. As an alternative to the Model 1000 terminal unit, it is intended for use when an analog signal for the tank level is required and where only one or two tanks are on location. The Model 3005 replaces the fuse board in the explosion-proof housing on top of the Siemens DLS and provides the same electrical protection. The Model 3005 requires 24 VDC and controls power to the level sensor. It powers the sensor on a programmed schedule, polls for the level value, powers the sensor down and outputs the analog signal. The configurations for the Model 3005 are stored in the digital level sensor EEPROM, allowing for easy board replacement if required.
