Manual Integrator Supercal 531 06-06-2011 31
6.2.5 Combined module
RS-232 interface with three relay outputs and four freely programmable outputs 0...20 mA, 4...20
mA, 0...10 VDC or 2…10 VDC.
The optional combined module with RS-232, three relay outputs and four freely programmable
outputs 0..20 mA, 4..20 mA, 0..10 VDC or 2…10 VDC combines at the same time:
The communication over the serial interface RS-232 (with a control system or all kinds of con-
troller or remote readout systems) with the transmission of status messages, alarm and/or er-
rors as relay output
the connection of the integrator Supercal 531 via the four freely selectable outputs to readout
or control systems required e.g. for building management applications.
The instantaneous values of the analogue output signals are active and need an external current
supply. The combined module of the Supercal 531 always requires mains voltage supply.
6.2.5.1 The RS-232 interface
Please see specification of module RS-232 with two relay outputs (point 6.2.3, page 28).
6.2.5.2 The relay outputs
Each output is galvanically isolated and contains 3 switching contacts.
6.2.5.3 The analogue outputs
They require an external current supply. Each current circuit can be set up individually as an ac-
tive, galvanically isolated analogue current output or analogue voltage output.
