ILUDEST® Single Case Controllers
Comprehensive range of microprocessor operated units for various control modes/functions.
The indication and modification of all set points and actual values is done via touchscreen LCD. With
optional Ethernet interface for the communication with a PC and CAN-BUS for the connection to other
controller types.
[DC/U]³ DISTILLATION CONTROL UNIT
With the following functions:
controlling of heating capacity (puls-package principle, 0-100 %)
adjustment of: reflux-/withdrawal ratio from 0:999…999:0 (s) total reflux, total withdrawal
display of sump and head temperature
possibility to preselect safety limit values, reaching of the same will lead to a total shut down of the
distillation process
[SU]³ SAFETY UNIT
For the connection of an existing heating mantle, a heating bath or any other heating element (max.
capacity 3.0 kW), whereby the power supply of the used element – an acoustic as well as an optical
alarm will be released simultaneously and a relais output is activated – will be interrupted in case of:
deficiency of cooling water supply
violation of 2 temperature limits (Pt-100)
violation of the minimum level for the reboiler content (response level value can be adjusted full scale)
[TA]³ TEMPERATURE DISPLAY
Digital indicating instrument for the connection of up to 8 Pt-100 PRTs (Platinum Resistance
Thermometers, Pt-100 sensors).
[VC]³ VACUUM CONTROLLER
Digital on-off controller with set-point adjustment and display of the actual value. Measuring- and
control range might be adapted, following the process requirements and the used pressure sensor
type.
[LC]³ LEVEL CONTROLLER
For the connection of an ILUDEST level indicator. With one of the following switch outputs (standard
option):
230 V, 16 A
24 V, 1 A
potential-free contact
[RT]³ REFLUX TIMER
reflux-/withdrawal time adjustable: 0:999...999:0, total reflux, total withdrawal temperature range:
0...350.0 °C accuracy: +/- 0.1°C (to reach the best accuracy, the controller can be calibrated with the
corresponding Pt-100 sensor)
[LS]³ POWER CONTROLLER
With the following functions:
power setting in 1% steps (0...100%)
additional analogue input for control voltage (0…10 V = 0…100%)
[DP]³ DIFFERENTIAL PRESSURE CONTROLLER
For display of column differential pressure
To „adjust“ a constant column load
To adjust the optimum separation efficiency of the column
with possibility to adjust the controller parameters (PID-controllers); thus, offering an optimum in
adapting the controller to the requirements of the existing plant and process, respectively.
measuring range: 1...50 mbar (as required)
control range: 1...50 mbar (as required)
ACCESSORIES
UNI-TOP
ILUDEST® program for data evaluation in WINDOWS™, for the data transfer from one of the controllers
described above via the interface RS 232 to an existing PC, for visualisation and data logging.
