The robust and compact process controller is designed to standardisa- Envelope Dimensions [mm] (see datasheet for details)
tion acc. to IEC 534-6 or VDI/VDE 3845 for assembly with linear and
rotary actuators. In addition, the remote version can be combined with Standard Version
Ø50 4 x M8
Bürkert process control valves. The digital electropneumatic SideCon- 4 x M6
trol process controller can be operated by the usual current and voltage
standard signals and can also be equipped with the Fieldbus interface 4x90° 45°
PROFIBUS DPV1. Additional to the digital display the valve opening is
signalled by a mechanical indicator element. The actual process value is 7,5 65
directly supplied to the device as 4-20 mA, PT100 or as frequency signal.
The process controller calculates the position setpoint for the subordi-
nated positioner through the variance comparison. Due to the analogue
feedback all analogue values on the controlling level can be transferred. 25
The parameterization of process controller and positioner can be carried 60
out automatically.
