Above all, the system is suitable for controlling and monitoring
temperature and other quantities, e.g. at machines in the plastics
processing and textile industries. Modular design offers the following
advantages: simplified project engineering, ordering and wiring,
easy new installation or retrofitting. Thanks to compact dimensions,
up to 32 controllers, even of different types, can be mounted to
a single rack. The 4-channel controller modules and the master unit
with control panel all function autonomously.
Master Unit:
* Configurations administration for all control
loops
* Display of actual value and setpoint, alarms and error conditions
* RS232 / TTY serial interface (20 mA)
Controller modules:
* Input: 4 thermocouples, types L, J and K with switchable reference
junction or Pt100 / Ni100, or 10 V or 20 mA standard signal, free
liniarization possible
* Control: two position / three position / step / continuous action
/ power controller / limit transducer
* PDPI algorithm with self-optimization
* Alternate setpoint, summated setpoint can be activated
* Outputs: 4 open collector outputs per relay for heating / cooling
or more / less and MIN-MAX alarms
Auxiliary power: Power supply via appropriate power pack: 110/230
VAC
