Model 3005 Analog Board product sheet

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.
