3.2  Principle of operation

SU 600 is a universal single signal conditioning instrument with inte-

grated level switches and display for continuous sensors. At the same 

time, it can serve as power supply unit for the connected sensor.SU 

600 is designed for connection of any 4 … 20 mA sensor. The instru-

ment is suitable for carrier rail, panel and surface mounting.

The SU 600 signal conditioning instrument can power connected 

sensors and process their measurement signals. The requested 

measured variable is shown on the display and also outputted to the 

integrated current output for further processing. The measurement 

signal can thus be transferred to a remote indication or a superor-

dinate control system. Two level relays for control of pumps or other 

devices are also integrated.

Wide-range power supply unit with 20 … 253 V AC/DC for worldwide 

use.
