DLC3010 Digital Level Controller Specifications
Available Configurations
DLC3010 Digital Level Controller:
Mounts on caged and cageless 249 sensors. See
tables 4 and 5 and sensor description.
Function: Transmitter
Communications Protocol: HART
Input Signal
Level, Interface, or Density: Rotary motion of torque
tube shaft proportional to changes in liquid level,
interface level, or density that change the buoyancy
of a displacer.
Process Temperature: Interface for 2- or 3-wire
100 ohm platinum RTD for sensing process
temperature, or optional user-entered target
temperature to permit compensating for changes in
specific gravity
Output Signal
Analog: 4 to 20 milliamperes DC (
J direct
action—increasing level, interface, or density
increases output; or
J reverse action—increasing
level, interface, or density decreases output)
High saturation: 20.5 mA
Low saturation: 3.8 mA
High alarm: 22.5 mA
Low Alarm: 3.7 mA
Only one of the above high/low alarm definitions is
available in a given configuration. NAMUR NE 43
compliant when high alarm level is selected.
Digital: HART 1200 Baud FSK (frequency shift keyed)
HART impedance requirements must be met to
enable communication. Total shunt impedance
across the master device connections (excluding the
master and transmitter impedance) must be between
230 and 1100 ohms. The transmitter HART receive
impedance is defined as:
Rx: 42K ohms and
Cx: 14 nF
In point-to-point configuration, analog and digital
signalling are available. The instrument may be
queried digitally for information, or placed in Burst
mode to regularly transmit unsolicited process
information digitally. In multi-drop mode, the output
current is fixed at 4 mA, and only digital
communication is available.

Note: At effective proportional band (PB)<100%,
linearity, dead band, repeatability, power supply
effect, and ambient temperature influence are
potentially derated by the factor (100%/PB)
Operating Influences
Power Supply Effect: Output changes <±0.2% of full
scale when supply varies between minimum and
maximum voltage specifications.
