Manual Integrator Supercal 531 06-06-2011 28
6.2 Optional communication modules
The two free module connection points in the integrator base part can be used to retrofit the below
mentioned optional communication modules without infringing the validity of the calibration. See
„The modular concept“ (point 3.1.), page 13
After installation of the modules, they are identified automatically within 30 seconds by the Super-
cal 531.
All optional communication modules can be read out and parameterised over the optical interface.
Due to the numerous retrofitting possibilities, the Supercal 531 allows a comprehensive transmis-
sion of the recorded data and the integration in many different process control systems and appli-
cations.
6.2.1 Analogue module with two outputs
6.2.1.1 Analogue modules with two outputs 4...20 mA
The optional analogue module with two outputs 4...20 mA enables the connection of the integrator
Supercal 531 to read-out or control systems required for e.g. building management applications.
The analogue module provides instantaneous values as analogue output signals. These outputs
are passive and require an external power supply. The power supply is coverd over the out puts
(9…24VDC). If equipped with an analogue module, the Supercal 531 must always be mains volt-
age-supplied.
Analogue module with two outputs 4..20 mA
An analogue module can always provide two of the below mentioned instantaneous values as gal-
vanically isolated analogue signal for each circuit:
Flow
Power
Temperature high
Temperature low
Temperature difference
Flow additional meter A1
Flow value additional meter A2
Up to two optional analogue modules can be operated in the integrator Supercal 531 at the same
time.
